Does Edelbrock's Catback exhausts and mufflers sound any good? How do they perform?

 

They're really deep like flowmasters but flow alot better, there is another similar cat-back called Random Technologies which makes Cat-Backs.

 

mitch, got any pics of your car? maybe a cardomain site? Sounds like we have identical cars. Mines got 48k miles...

 

Yes we have identical cars, My dad is buying a digital camera soon and ill take pictures of it then.

 

Alrite make sure you get a cardomain site and let me know then!!

 

I have an edelbrock catback and LOVE it. Its my origional mod back in 99 and its the only mod I have never changed. Its very deep sounding throughout the RPM range + its VERY quiet at like 60mph on the highway which is nice too. I'll always keep mine.

 

if i buy their catback will the split rear duel exhaust go up and angle downward like my stock exhaust or will it come straight out?

 

Stock. I also like that they have a lifetime replacement warrenty on the muffler. Muffler is stainless. Its going on 7 years on my car and I have a spot or too of surface, but nothing an sos pad can take care of. As for the pipes, theres not a spot on them.

 

are their any sensors i have to worry about when i take off my old exhaust and converters?

 

Nope, no sensors or anything....I have the Edelbrock cat-back
also, with a Walker hi-flo cat, and it is fabulous. Very throaty
and mean sounding.....

 

Awesome

Even though i'm going to have stock manifolds How much horsepower/ torque could i expect from my:

Edelbrock Cat-Back Exhaust
Dynomax High Flow Converter?

 

probably 10hp or so......... Just enough that you will probably notice difference but, not much more is my opinion......

 

really? I expected around 20 hp 30 ft/lb of torque because someone took a exhaust from a tpi 305 Camaro and it gave them 8 hp and 20 ft/lb of torque

 

I mean no disrespect but no way can he expect that little hp. Any decent catback system will give you about 25hp additional to the engine crank and around 15hp to the wheels.

With a high flow cat converter you could expect another 5hp, so that makes it around 20hp.

One of the big issues with the TBI cars is it's form of restrictive exhaust..any after market exhaust will perform the same gains, it just depends on the type of sound you want.

From what I hear edelbrock sounds very nice on the TBI cars, I was going to order one but decided it would be cheaper and I would get more flow if I went with my own custom set up.

So as of now I am running a bullet muffler 3 inch in and out single tail pipe, I'll be ordering my 3 inch i-pipe within the coming weeks. But in all honesty, the Edelbrock is good enough and allows just as much flow as a bullet does.

Good choice!

EDIT: M1tch, if you are dead set on an Edelbrock cat back that's your choice, but I wouldn't rule out Hooker catback either, I heard some of them on a TBI based car and they sound really good. They're a bit cheaper than Edelbrock as well and they offer the 3 inch i-pipe just as Edelbrock does. But again choice is up to you

 

Yea I heard hooker performs well. Whats the difference in between Edelbrock's and Hooker's mufflers? Or are they about the same?

Lastly, What does H.O mean when im looking for exhausts? On Jegs it says one Hooker exhaust is for 305 H.O tpi. Then another says 305 non H.O..

Sorry for the questions, just trying to make the right choice.. Thanks

Edit: this is the Edelbrock cat-back im getting its the first one on the list.

You want to get the NON H.O. since your car is an LO3...as far as the differences between the hookers and the edelbrock....minimal if at all.

Both systems feature 3 inch i-pipe diameters, its just that the hooker system costs less. Both systems are just as durable as one another, its just the sound that differentiates the both of them.

Sounds like you want the Edelbrock, and if thats what you want go for it. I have several edelbrock products on my car now and I am happy with them, I may still buy the catback if I decide not to pursue with my own set up, but thats highly unlikely seeing as how I love the way my car sounds as of now. Again it's a matter of preference, whichever route you choose to take is the best one. I am just making suggestions not making the decisions for you

EDIT: On that note, if possible I was wondering if Edelbrock sells their i-pipes seperately. That may be a good purchase for me...

 

So the Edelbrock exhaust im getting will fit? The exhaust will pretty much fit any thirdgen camaro right?

 

It'll fit no problems, those Edelbrock catbacks include the stock hangers so it'll bolt on with no questions asked...

 

Thanks!

 

They do.

 

I would forever be in your debt if you could link me to a possible sit that sells them. I wanna look at my choices for an I-pipe and not just stick to the ones summit gave me...


Pretty please

 

HO is for high output, non HO is for a standard engine. Early years the HO would have had a three inch exhaust and the standard was smaller at 2 1/2 I think. Later cars had dual cats on the HO. Probably should crawl under there and measure your pipes to be sure what to order as you may run into problems in the front matching up to the pipes.

 

Summit Racing sells them. I check about a year ago and needed a new I pipe. I called Edelbrock and they gave me a Part number for the I pipe AND over axle pipe. I poped it into summits site using the EDL-***** whatever number edelbrock gave me and it came up. It I remembor corectly both pipes were around 70 bucks.

Sorry, but I do not have the part numbers anymore.

 

bah, no worries, the information you have given me is enough. I'll be sure to give Edelbrock a call and get that part number so I can order those i-pipes.

70 bucks isn't bad, I take it 3 inch piping? Or 2.5 inch?

Anything bigger than 2.25 inch is good enough for me

 

Listen guys, I would love to think a catback and high flow cat will net you 20 WHP but i am skeptical. I'm surprised no one else has alerted you to the notion that you may only get 5 WHP out of a catback (dont know how much more a high flow cat would net). I can't say with certainty that you will get 'this much HP' from a catback, but i have done alot of reading, and alot of people believe a catback will only get you about 5 WHP. Reason being is that yea LO3 exhausts are really restrictive, so by adding a 3 inch catback and cat you will open it up alittle bit, but the manifolds and y-pipe are still choking it, and the exhaust has to go before them before it can even get to the cat and catback.

Maybe if he went with an aftermarket exhaust with the same stock piping diameters he could expect that much...

Truth is, it really depends on what kind of gain you will see. I have seen several guys adding on a cat back off a stock TPI to their TBI cars and gaining as much as 7hp more and about 20 ft lbs of torque...I have also seen one dude put in a catback exhaust, with an open element air filter and he got about 13hp total...

It depends on the type of tune your car is in. The least, and I mean absolute worst he can expect from a catback gain is 10 hp. Many people will say its not worth it, but this is a very good starting mod on LO3 cars. It doesn't take much to turn around on the air and fuel delivery system. He can expect up to 15hp just as much as the next guy.

As far as the high flow cat, thats a rough estimate, getting a high flow cat in my opinion really won't make a seat of the pants difference. I think the most you could gain out of a measley converter is 5hp...I'll be running straight pipes on my car anyway so it doesn't hurt me

 

Don't get me wrong, i love my car and im putting a high flo cat, a catback (either GMMG or hooker depending on how much $$ i have), and an open element on my car in the spring. If my car will respond to my mods with 20+ HP i'd be estactic. The only true way to tell is to dyno and thats not really an option for me. I'm not trying to discredit any of what your saying, but we do need to point out the fact that the car will still have its HORRIBLE stock manifolds and y pipe which is still gona limit it. So if a catback can net Mitch (and myself for that matter) 15HP, then hell yea thats awesome...if not..oh well--im still gonna put one on.

 

I 've had my edelbrock system for two years. I went from a dual cat to a 3" single cat. I didn't feel any difference. I been thru several brands. Flowmaster, Borla (dual tips exits out the driver's side) I had my wife video the camaro takeing a quick acceleration. I don't know how to post a video, to me it's the closest sound to a mustang.

 

This might disapoint some people..

I went to some place called Big Al's Muffler & Brakes.. my dad told me to go there because he got his exhaust tips welded on there for his Camaro SS.

They gave me a deal on a 3" catback exhaust, flowmaster 80 series muffler, flowmaster tips, and a magnaflow high-flow catalytic converter for $475 installed.

Now thats a good deal. Some places were trying to charge me $400 with just a flowmaster muffler and tips. BS

I couldnt pass up the deal.. Btw it sounds good

____________________________________________________

I know people have been dissing flowmaster but I'm sure it flows WAY better than it ever did before

 

OMG! HOW COULD YOU! WHY FLOWMASTERS AUGH! THEY SUCK!!! I am just kidding by the way, that's a bank deal on the exhaust system. If the car sounds good now, you should wait another couple of weeks for the flowmaster 80 muffler to "break in" then it'll sound almost twice as deep (atleast this is what I have been told) I've been trying to find a muffler shop that actually sells catback exhaust systems in my town, but believe it or not, there is none. And I believe every muffler I called wanted 250 dollars installation for a catback, which in theory isn't "terrible"

Flowmasters are just fine for the time being, down the road you may want to switch em' out but. Nothing is wrong with em' I don't own one, so I cannot comment on one but I have heard quite a few of them on some cars and they sound nice and bubbly.

Hope your happy with that.

 

seriously it gets deeper? hell yea then

 

come on mitch when you gona post some pictures of that badboy? I dont care if you gotta go shoplift a digital camera...JUST DO IT!!!

 

If people stopped egging my car out of jealousy i might be able to get pictures when my dad gets the camera.. I think I might have to get out my Mossberg 835 and light up some people
