i just bought a 1998 z28 with pacesetter longtube headers, no cats, offroad y pipe and slp loudmouth 1, but my parents are making me replace the entire system so its legal and not so loud i was looking online and found complete header kits from MAC http://www.lmperformance.com/562/1.html it looks like a good deal and was wondering what you guys think. and also it looks like i would have to by the MAC cat back system since the y pipe is 2 1/2 inches so it would match. right now i have a 3 inch y pipe, are there kits like the one i linked that come with a 3 inch y pipe but still have cats?

 

It's hard to find a whole package like that. Usually you mix and match or buy them separate. It seems like a good deal also!

 

thanks
