I do not want to double post everything but you can see pics of the exhaust here

https://www.thirdgen.org/techbb2/sho...hreadid=249030

I went with a single out the left side cherry bomb exhaust. Everything from the cat area back is welded and then I used jb weld to cover the seams n any pin holes.

Well since the new exhaust it pops real loud once heated up. Like clock work almost. every 1-2 sec it sound like someone hits the frame with a hammer.

I am about 99% sure its the new exhaust.
The sound showed up after installing it.

Not even sure of anyone can help but maybe someone else dealt with this after a new exhaust install that was welded.


I may have to stuff some insulation or something in n around the pipe to see if it helps.
That or turn up the radio. But I really enjoy the new sound of my car / muffler. The single exit on the left is neat. Even neater is rattling the windows of slow people in the left lane as I pass them in the right.

 

Of course there's somebody under there. You can see their feet in one of the pics...

It's probably heat expansion of the muffler and/or exhaust. It may subside after whatever is popping finally breaks free, or it may continue for the rest of its life.

 

haha ok had the same thing happen with my volvo for one to much back pressure and the popping you are most likely hearing is a backfire. i had the same thing after you pound the gs and the car is slowing down you hear pop pop pop then all of a sudden a bang?

 

From the linked thread: "It will even do it 2-3 times after the car is shut off."

I assumed the car wouldn't backfire when it isn't running.

 

The dam thing still does it. Its for sure heat related as it wont do it cold. But dam its driving me nuts. I am thinking though its my aluminum heat shield. As its not a steel pin.

Thinking.........

That before with the large type stock muffler the heat shield is heated evenly as almost out of sight as the muffler covers it. But with the cherry bomb its is only heating a small part of the very center of the heat shield making it heat n cool funky making that sound.

Id just remove the sucker but hot exhaust n the gas tank don't mix. Maybe I can bend or wrap it around the exhaust some, get it closer so that the whole thing heats up.


just thinking out loud

 

OK I pin pointed the noise. Its the right side of my cool tip. You can see how the back are open to keep them cool. I finally just started touching parts till I found the pat making the noise. Not sure how just that one piece can do it but its it. Anywhere else you touch the pop feel soft but grab just that part and you fell it dead on.

Even after the tips were cool enough to touch by bare hand it did it every 5-6 sec. Its fricking lame to a point. Not sure how to correct it as everything is welded. Though the other tip might do the same thing if it wasn't touching the body seam. Might try jamming a piece of metal in there to suck the heat away. Who knows but mans it frickin strange. not to mention loud and annoying.

 

Ok I was wrong again. It is the right side tip but it is the one touching the body seam not the left. So I will assume again that the right tip touching the body is cooling it off strange making it pop.

But it sucks as I can't really move it. The exhaust is very tight against the body. I used a c clamp to pull the exhaust hanger and the pipe together tight and then welded the hanger one.

Maybe there is a place for exhaust clamps, as once welded. its stuck.

 

ive always wondered why certian cars make that sound!

 

I sure wish someone else had dealt with this. its driving me nuts. I have tried many things so far. jamming wood in between the body n tip, stuffing insulation in and around the tip. I can't even get the sound muffled a tad.

 

is that one of those $18 cherry bomb glasspacks??? i have one of those and i noticed that when it heats up that it starts to ping. like when i had it off my car and i had a torch in it it got hot and made that ping sound...idunno if that's it for u but it's a thought

 

my damn Flow Bastard is now poping every time i shift.. almost sounds like a damn back fire... only started doing this in the last 2 months too... i frickin hate it..

im going with magna flow next.. just a muffler replacment, i already have a 3" cat and 3" piping all the way back.

 

If I hadn't stepped on and broke my torch tip I was thinking of heating it up as much as I could and then dousing it with cold water.

try and shock it well. Ive taking two long drive and ten threw water on it and it did **** it off well. Make lots of awful noise and it did 20mins worth of pins n pops all at once.

Be neat if I could get it red hot though.

 

LOL cherry bombs POP.

It's just what cherry bombs do.
If you don't want poping, get rid of the cherry bombs.

 

I have / had cherry bombs on several different cars and never heard a peep from them. I have one on my Buick wagon. been there about 3 years.

 

Well water quenching has fix things up. I no longer hear loud pop n pings while driving. Only when the car is shut off you just hear the normal sounding tings n such but real soft and low.

Before even after the car was off I could hear it 20' away in the house.

But the water trick has been working. Its nice to just drive around and listen to my exhaust. Its real nice. They say it can't be done but a V6 can sound like an 8. No winny sound even all the way up to 5000rpm, the down shifts are mean and low with that nice grumble.

If you want your 6 to sound like an 8 with out fancy resonators a cherry bomb is the way to go.

Trust me.

 

or add two mor cylindars!









sorry, you had to know that that was coming though man!

 

I would gladly listen to your moronic V6 bashing if you could show me one V8 that you can drive like you stole it and still get 26-27mph in the city.

Ya can't. I would not take a chevy V8 if you gave it to me.
Though I might take it but would sell it.



Had a V8 Camaro, been there, done that, boring.

 

wow

not v6 bashing. i've had several. i liked them. but i go much faster with my v8. 25-27 mpg city? well, i can't say that any of my v6 cars got that kinda mileage. i got that on the highway. my 13 second v8 gets 20-22 with a holley sitting on top with 3.73's out back.

you need to settle down man. in no way shape form or fashion was a attempting to bash the v6. heck, if you go to my cardomain site, you will see a whole page dedicated to the almighty 60*v6. but man, i got tired of trying to be different. being different doesn't win races.

so yeah, i was just frickin' joking about that whole deal.

 

Well you will need to control your funny bone. You will find most V6 owners around here are easily offended as most of this board is anti V6.

You can barley ask question about your car in the V6 section with out getting bashed, let alone anywhere else.

Ask about some speakers and mention you have a V6 and 20 people will reply to just tell you how that money is better spent on a V8 then new speakers.

Try it out some time. They will ignore your question and just blab how you shouldn't do anything to a V6 [paint, tune up, rebuild, turbo, spray] but jam a V8 in it.

 

hence the reason i am no longer apart of the v6 crowd, i got easily offended too. there is no need for the defensiveness though man. i get so tired of people defending the little v6. if you want to do a big power v6 build up, go for it man, but i don't want to waist the money nor the r&d time as noone up to this point makes a mass produced performance line for the sad little motor. it just makes sense man, big motor equals big easy power. that's what wins races, not nice paint or big speaker. unfortunately, MOST OF the v6 crowd is all about looking like they are fast, not actually being it. not saying you are or that everyone is, but a lot of them are. man, i was there just two years ago! I KNOW ALL ABOUT IT!!!

TAKE THIS AS:
A general statement made towards the v6 populasin general coming from a former v6 owner/tuner.

DO NOT TAKE THIS AS: A statement related to those who are not try to make there v6 "the fastest 60* on a quest for respect" or a direct attack towards you and yours.

if you have any further disagreements or immature attacks towards me, please pm me.

 

your missing out then. !4 sec cars that are good on gas are fun.

There is already a turbo kit aboutto hit the market but we have many turbo guys, a few blowers and lots of spray.

find a 14sec car thats good on gas and it must be ****?

well not if its American made. lack of innovation and small minded ness make people think you must have 5 liter plus to go fast.
3 liters is more then plenty if done right.

 

i didn't buy an f-body to have a car good on gas. i bought it cause they look good and go fast if built right. if you bought one for gas mileage, more power to ya. the fact that i get 20+mpg in my 13 second car is just a plus.

 

LIAR, i remember an old thread , you were gonna get a 305 from a buddy of yours, You seemed happy as a pig in ****. Even bought a manifold for it.

 

I'll give you another challenge,


take $6000 and a 68-80 SBC
using stock iron heads, block and intake.
You can mod them as needed And you must get 500+ hp
without out spray or other froms of turbo like devise.

Just a carb and mostly modded stock parts

Then put it in a 3800lb car and do 10s in the 1/4


It will never happen with a SBC

So why build one???



BTW a SBB can do all those above. New aluminum intake and heads should be cast this summer by TA performance. 750+ hp will happen in a SBB.

 

If the sbc is limited to mainly stock heads,block and intake then why is it that your pos sbb isnt?

Hate to brake it to you but there are sbc's that have broke the 750 you speak of.

How do you v6 guys come up with these ideas? Do you guys drink some "special" water or something?

You people talk about running 11's with a 60* v6 with some home made turbo put on it and cry like babies when someone disagrees with the gains you'll get. YET you bad mouth a SBC!?!?!?!!?

I think you'd be better off selling what your smoking.

 

its because of the little dog big dog syndrome .....if 90% of them were given a chance to put a v8 in thier car they would in a heart beat for sure but instead they stand all defensive and get all mad when someone like me says something like ........THERES NO REPLACEMENT FOR DISPLACEMENT........i mean its only common sense and i dont car what thier arguements are its the truth no matter what you have to say i can put the same parts on my sbc and out run your 6 ....if you turbo i can turb if you spray i can spray if you use a blower well you get the hint its gonna get chewed up and spit out no doubt about it .......

 

wait, what is a sbb? why on earth would you build a sbc with $6000 with a stock block, head, intake? am i the onhly one that thinks that his "challenge" makes absolute no sense? this is the most useless argument i have ever been a part of. you will never be able to make the power from a 60* that you will from a sbc. just like you won't from an sbc as you will from a bbc. anything you do to the 60* will make more power on a sbc. just like that with the sbc>bbc.

take a 60* with a set of custom aluminum heads, custom grind cam, forged bottom end, big turbo, the works.

then, take the same money, build a sbc with all the same, tell me it won't make more power! if you wanna talk about mpg. make sure that the sbc is fuel injected just like the 60* would be. then just tune it for the street with your prom tuning crap. mpg is just all about how heavy your foot is!

you can make more power with a streetable motor with the same amount of money.

oh, and if you make all that power out of your little v6, then your little v6 tranny (manual or auto) is going to need beefing up or replacement. while you have that out, just put in a v8 tranny instead. than all you have to do is change your motor mounts, which is much easier than fabbing up some crazy turbo kit for your v6.

 

sbb= small block buick. Yes his other car is a buick

 

sbb = Small block buick. I have no clue about what a 350 buick has to do with a 350 chevy or a 2.8 V6.

No kidding the small block chevy market is so huge it would be moronic to use stock iron heads and intake on a $6000 Budget

I'm with you there, so what if a small block chevy can't make 500hp with stock heads, block, and intake! If you put 6G's into a 350 and 6G's into a 2.8 with all of your stipulations (stock heads, intake, block and no power adders) the 350 will make more power.

 

 

Back on subject, my friends cars exhaust made the same noise. Did it forever.

 

LOL man thats funny ...LOL...

 

when a car looks like that, a cherry bomb is the only appropriate option
