Is there a hp increase in getting the whole magnaflow catback? I love the sound of them but i want to keep my stock z28 exhaust tips. So i guess my question is where can i get just the muffler? Thanks in advance

That's what I just did and i plan to have the muffler installed this week.

Third down on the page, they have both the stainless and aluminized one. The muffler is the biggest bottleneck in the system, getting the catback over the just the muffler won't give you much more power.

the catback will net more overall power due to the 3" I pipe and and over the axel piping then just the muffler alone but not much. but many people have swapped muffler only and had great results.

some1 is having a GP on the magnaflow muffler alone...check sponsor special and group purchase section.

the catback is better becuase of the pipe sizes but hey its a magnaflow

EDIT: Damn it JRP you beat me to it! lol

Thanks for all of the help on this. I saw the group purchase for 70.00 but i was wondering if it was for the stainless muffler. Thanks again
