Anybody know anything about sounds, performence, and so on about Mac exhaust?(muffler or cat-back sys.)Thanks!

------------------
92 Firebird
305TBI, Full exhaust, air intake, 16" wheels, Tbi spacer

 

I would like to know the same thing

 

any help?

 

THEY ROCK! Excellent Fit and sound way more beastly than Flowmaster does. Definitely woth getting!

 

Does anybody know of any fitment issues for the MAC catback system on an '82 Z28 305 4bbl?

Im pretty sure I have it narrowed down to this system

any help would be greatly appreciated, thanks!

 

my car had this on it when i got it, i love the way it sounds.

 

Has anybody installed this on an '82 Z28 with 305 4bbl and 4spd manual transmission? (or similar vehicle)

MAC lists this cat back system (MAC Part# TK8691) to fit '86-'92 What kind of problems (if any) should I expect?

Thanks, I just bought this car, so im new to the forums, pics will be posted as soon as I give her a full doll up.

Any help will be greatly appreciated!

 

I guess the cat may be a different size or something, that could be the difference.

 

Does anybody else have some input on this? It would definitely help in my purchase decision. If this would be a nightmare to install, I will have to consider something else

 

They are no nightmare to install, they go in the same place as all the stock exhaust componets. I have them on my car i like them, and they sound great, though with my application it seems to be a tad bit restrictive. I eventually would like to try and make a true dual set up with mac flow paths which would flow better than a y-pipe this will be a nightmare to install. IMO mac cat backs are a good choice.
