I noticed that some mufflers are made to decrease interior resonance but I want the oppisite. I want to hear my engine while I am driving it. I have a stock 350 engine with factory exhaust setup. I heard that flowmasters 80 are can be heard loudly in the interior. How about pypes violator muffler?

 

how would an muffler affect engine sound? Honestly i aint going to try to help here as all would be pointless.

 

No, what I mean is that some people hate having a loud car becuase it interferes with listining to the radio or playing music, but I don't care about that. I just want a really loud car and a muffler that I can hear loudly while inside the car.

 

then just run open headers/manifolds

 

I heard that running open headers or manifolds will damage exhaust valves because of the massive decrease in back pressure

 

Well have you not considered the others around you? Plus you gotta keep in mind of sound regulations and what not. If you want fairly loud look into an GMMG catback along with some hooker headers/y-pipe and an magnaflow cat. Or instead of GMMG, Borla is pretty loud when you step on it.

I would seiously put an lot of though into your exhuast setup, loud doesnt mean good. And you wont always want loud ALL the time, like magnaflow's catback is quite on idle but screams up top. Again, please reconsider.

 

I really only want a deep throaghty/ gurgling sound at idle as can be heards from old school cars from the late 60's to early 70's. I found that no muffler gave a little gurgle but not much so was thinking that maybe using pypes muffler and run dual tips will help.

 

Please get something that is going to sound good, not just loud. There was this idiot at my highschool with a 93 sierra with a 350, he had a cherry bomb welded on backwards which basically made it to where the baffles didn't do anything.... It was loud but sounded atrocious. Remember, horsepower makes noise, not the other way around.

 

Im kinda confused are you looking for purely just an muffler, do you want just an catback, or do you want to do full exhuast? (headers,y-pipe,cat,catback)

The gmmg is supposely sound alot like the muscle cars of the 60's but they are outrageous on price, an magnaflow cat back can be found for 300 up. Which is btw VERY free flowing and has an very deep, also 60's muscle car like tone.

Admittly not as loud on idle/cruise but this is in most cases an benifit but they SCREAM when you step on it. the magnaflow catback along with magnaflow cat and hooker 2055's will really wake up the 350 and the car will most defintly be louder with headers and whatnot then just an muffler or catback of same model, plus an higher lift cam will also help with the sound.

 

Thanks for all the help but I am lookinng solely for a muffler. I don't have enough momey to spend on an entire system since Im rebuilding a 383 stroker at this time.

 

do you have an competly stock system on there right now? How are you expecting for the car to breath?

 

Fab up a simple dual exhaust setup using any muffler of your choice and have the exhaust dumped before the rear axle with turn downs, facing about 45 deg downward angle to the sides of the car.

You will hear that very nicely inside the car

On a regular catback, flowmaster 80 did have some interior drone/noise around the 2000-2600 rpm range. But every catback configuration seems to have this to a degree.

If you put a dynomax bullet, or ultraflo, or a magnaflow straight-thru type muffler in the I-pipe section, you will have good interior exhaust note.

 

this would have gotten you less defensive responses. Huge different between a deep sounding exhaust that makes you feel good about your car, and a " loud " one that offends and sounds like poop. Makes me think of those little cars people pay money to sound like motorcycles..

On the considering people around you note, hate to see a sweet car be shunned because its so loud.

Hope you found/ find something you like . On mine its suposed to be an edlebrock setup, but most my firebirds/ cameros came with nice deep sounding stock when nothing is leaking. Replaced mine with a " tuned exhaust on an 82 in high school. Thing sounded amazing, it was laying in a pile of exhaust set ups on a place that used to have a ton of camero parts.
And my opinion if it drowns out ur radio, you need new speakers or your exhaust is broke lol. I mean should always be able to hear/ fell your engine on a manual though.

 

With manifolds and a cat the sound will be limited of course.

I have experienced the annoyingly loud exhaust on a hour drive and that was it for me, it was "fixed" as soon as I could. This was shorty headers with a dynomax turbo muffler where the cat goes dumping off right there in a 305 Z28. Yeah it sounds great ripping down the street but that's it, on long trips it makes your ears ring for a good hour after. Just putting the muffler where it was supposed to be fixed it for me.

I think the "old" sound people refer to is glass packs. Personally I think those sound like garbage.

If the rest of the exhaust is stock it doesn't matter what you put back there it isn't going any faster. The most annoying muffler I've owned was the flowmaster that came on the car. It was embarrassing honestly it sounds rowdy but was an incredible turd.

 

What???? I can't hear you!

 

Do what I did, use solid motor mounts, build a fully welded exhaust and hang it off the motor & tranny using solid mounts. It'll make a hell of a ruckus, you can feel the cylinder firing LOL I'd bet I could diagnose an ignition problem with my ***

 

Once you decide on a muffler and if its not loud enough for you, you can have a "cut out" put on the pipe just after the cat. You can open and close it as much as you want manually or you can get a electric one that runs on a switch. You said loud and that should do it. And the manual ones are inexpensive.

 

Nothing's going to be loud if you retain the factory crinkle-bent intermediate pipe.

Also, like others have said, "loud" sounds like *** on a stock motor. Nothing you do to a stock TPI 350 exhaust is going to make the car sound like a 60's muscle car. The TPI doesn't have the camshaft or the compression to make those kinds of sounds... nevermind the completely different exhaust scheme.

That said, swapping the stock muffler for a different aftermarket muffler CAN improve the quality of the sound. I'm running a Thrush chambered muffler (single in/single out) on my GTA with the stock intermediate pipe. It's not loud, but it sounds great. I had a Pypes Violator on there temporarily and it sounded a little different, but wasn't much louder.

 

The type of muffler and location can greatly impact the interior resonance however. you can have a car thats relatively quiet on the outside but resonants like an SOB on the inside making you think the car is much louder than it is. My flowmaster 80 had some loud interior resonance when around that magical 2000-2500 rpm zone but it really wasnt all that loud compared to a gutted cat chambered tube setup on the same motor.

 

Go with the flowmaster 1 chamber mufflers loud as hell and noisy inside. Put it this way when I put my 11month old daughter in the back seat she falls asleep from all the vibrations from that muffler.

I also have videos on you tube you could check out. Search for kingbikerhead or elmazeton805 and go through the videos.

If you don't have emissions testing, you can replace the catalytic converter with a piece of straight pipe or take it out, hammer the internals out, and then reinstall it. One step further would be to cut the stock muffler off completely and install a cherry bomb muffler where the cat used to be, with the exhaust ending before the rear end. This was one of my first 'mods' to make it sound like I had a fast car.

 

Get a 90 degree bend the same diameter as the pipe after the cat, a hole saw and saws all. Cut your intermediate exhaust pipe just before the rear seat dip. Using the hole saw, cut a hole in the floor. Now, attach the 90 degree bend to the intermediate pipe pointing inside the car. Now it'll be loud inside and not outside to bug everyone else. Might want to crack your window to let in fresh air.

 

HA HA HA, I Agree! Thats a good one. IROCSTANGS should of followed his first instinct(tread #2).

 

this. but leave the window closed for more dB's y0! if you open it all that siqq sound will escape.

 

Buy a $30 cutout and have an exhaust shop weld it in near the front of the exhaust system (like, under the passenger seat, for example). This will get you what you want, but then you can also "turn it off" and go back to how it was before when you want to.

 

get a cam and it'll rumble. if you dont have a cam it's not going to sound good or old. that's my opinion. i run headers no cat all mandrel bent to the rear no muffler and a cam so i know loud and good. on my truck i had some old headers and cut all the tubes before the collector. it would shoot flames at the ground when i drove. it got annoying having the floorboards and everything vibrating off the exhaust. thats why now i go out the rear with no mufflers on both my truck and camaro now, less vibrations and less in my head

 

get a thirdgen with rotted out floorboards and cut your exhaust off where the cat usualy sits

 

oh yea, you could take out the carpet and roll the windows down

 

Just before the cat, you can install a motorized cut-out system with a turn down pipe. At the flip of a switch, you can adjust when you want a fully open exaust system, or legal exaust systems.






These are the pieces you'll need: one cut-out motor, out cut-out y-pipe, and one turn down pipe. They all come in different sizes. When you order, dont get confused with 3" inside and 3" outside diameters. Here is more or less how the mod will look like,

 

thats usually the results of a big cam

 

I also vote for cut out, and pull all your sound insulation out.

 

I did hooker headers true duals to a pair of spin tech drag mufflers and it sounds pretty bad *** I know my nieghbors hate it.. I have a comp 292 magnum cam too though

 

yeah a big cam will give you that rough uneven sounding idle.

 

hearing my car keeps my foot out of the gas. in which i save gas and sometimes im lucky to hit 12 mpg. here is an exhaust that will help you out. sinister 4in exhaust.
