Stock V6 to Z28 muffler swap

[camaro_fred]

Hi:

I know this subject isn't new in this group, but I haven't found the answers to some questions.
I want to replace my V6 stock muffler (single out) by a Z stock muffler.

Questions :
_ Are the brackets compatible (location)?
_ Are all 4th gen mufflers same shape (I mean, could I use any year from 1993 to present)?
_ What increase in noise will I get?
_ Will sound be deeper and/or louder?
_ How much HP gain can I expect? (my car is stock )
_ Are the pipe dia. compatible?
_ Is the Z muffler steel or stainless steel?

Any help will be greatly appreciated,

Fred

YES

Not much IMHO

_ Will sound be deeper and/or louder?
I don't think ther ewill be much if any difference. it's teh air that is pushed through it ath make sthe difference and you are not increasing that any.

_ How much HP gain can I expect? (my car is stock )
0 that I know of

_ Are the pipe dia. compatible?
I think the V6 is .25 smaller

_ Is the Z muffler steel or stainless steel?
Steel I believe

Yes you will notice a deeper/louder sound, but not by much.

I bought a TA muffiler with the ovel tips for mine, full cat back and it didnt fit.
Many things are in the way, the 3" pipe wont meat up with the 2.25", it would also require 2 adapters one ontop of another which would also make it less sturdy and takes up 9" of space,(I tried it) It also required that the rear axle be droped and the pan hard arm is very tight back there.
I have yet to find anything that I like yet so I still have the singel out muffiler too.

not true. of course you have to adapt the 3" to the 2.25" that is stock on our cars, but a welder can do that no prob. the rear axle doesn't have to be dropped and the panhard rod doesn't get in the way whatsoever. and the 9" of space you are talking about...wtf? how do i know? i have one on my car and watched the guy put it on from already stock v6 car. he had absolutely no problems and downsizing the 3" pipe to fit on the 2.25" took less than 2 minutes. i dunno how you had those problems, but they are completely compatable. maybe next time you should take it to an exhaust shop.

I have a Z catback on mine and am quite happy with it. You won't mistake it for an aftermarket muffler (Flowmaster, Borla, etc), but it did make a nice change in sound. It didn't do much for power, but I still run the stock air intake. As was said, a welder should be able to mate the different size pipes. When mine was done, the guy used a sleeze made from scrap pipe to fit around the smaller pipe and inside the larger one. It helped to fill the gap and made a nice strong weld. Don't let the shop try to bend and crimp the larger pipe around the smaller one. If you were trying to adapt the system using reducers and clamps I could see how you might need the kind of space that Chrisz24 is talking about, but I would suggest getting it welded up.
For my car, the front hanger, the one just behind the axle, was the same as my stock system. But the driver's side hanger wasn't, so we welded on a tab to the driver's side pipe and used the stock strap instead of the newer style rubber block and hook that was on the new exhaust.

If you want to put a one piece catback on the car, like the late model V8 systems are, you do need to drop one side of the axle and the panhard. That is actually what the guy who I bought my system from did, because he was putting on a used Corsa that had arleady been welded together and he didn't want to cut it. But when I took the system in to get installed, the welder just cut the system right before the muffler and rewelded them once it was on the car.

He asked, I responded, and your post served what purpose? Also note that I was talking about an entire catback, and stated that it didn't do anything for power because I still run a basically stock car. If you want to argue that catbacks cannot free up power, I would really like to know why thousands of people seem to think otherwise??

if i didn't think catback systems added anything, i would have said so.

:rolleyes:

my point to you WAS that although the stock z28 catback may not be doing much for you, no catback system is going to do much more for you. you might see a 2-3 hp difference between a stock z28 catback and a really nice aftermarket one--and that gain is next to nothing.

chill dude.

That is true, and also why I said I had a stock car, just like the thread starter. I didn't say another system would give me more, I said this one didn't give any. If you had posted: <blockquote>quote:</font><hr>my point to you WAS that although the stock z28 catback may not be doing much for you, no catback system is going to do much more for you. you might see a 2-3 hp difference between a stock z28 catback and a really nice aftermarket one--and that gain is next to nothing. <hr></blockquote>in the first place, I wouldn't have said another word. But instead you wanted to be cute, so I responded. [img]smile.gif[/img]
