Opinions on MAC Performance exhaust
Hey guys, I'm just wondering what your Opinions are on the MAC Performance exhaust systems. Any input would be great, I'm looking at the whole setup, including the headers. Thanks for the help!

I have the exhaust,and I like it except I find the 3 1/2 inch tips a bit too big for my taste...

I am impressed with the quality of their 4th gen headers, and their flow path mufflers sound bad ***.......:hail:

I know nothing about their headers, but the cat back system is loud as hell and sounds awesome. Easy install, fits better than stock. Easily removed, because of the way it assembles. Ever do a fuel pump with a muffler that's rusted to pipe? Enough said. Unlike Iroc4ever I think the 3" slash cut tailpipes look bad-azz. I just got my chrome tails in last week and can't wait to install them. Highly recommend the cat back!

MAC makes great products. Check with your local laws though about exhuasts. One of our members put it on his car and it was so loud that he kept getting tickets. Just ta warn you. But other than that, good exhausts.

mac is the shizzle as far as what it costs and what you get. the mufflers from mac are alot like a flowmaster except they actually flow, I was really amazed by some of the gains I saw on our dyno back when we had it. mac makes a pile of cool stuff for our cars. They are one of the few companies that decided to not just simply "skip over" the 3rd gens. Take a look for thier website and remember the prices listed there are much much higher than mac dealers sell for...
