v6 cat back exhaust

6banger96 · October 16th, 2007, 11:00 PM

hi, i put a mac dual cat back exhaust on my car and every now and then the piping rattles against the axle. is this just because the piping is larger than the stock exhaust? does anyone else have this problem? is there any way to stop it? thanks

i have another question. i have mac shorty headers and flow tubes, and am going to get a mac h pipe. with this setup will the mac pro chamber h pipe for the 96-98 gt bolt right up to my 96 v6? or will i have to go with the off road hpipe thats made for the v6?

for the first question. take some pics of the undercarriage. could be that they didnt bend the pipes right.

I had the same problem with an MRT exhaust. There are 2 things you can try. Loosen the pipe (after it is cooled) and try and seperate it alittle. I moved mine about 1/4 inch off the suspension and still had plenty of clamping area. Also you can take your largest socket and place it under the tight spot. Heat up the pipe and make a dimple/bend in the pipe. After doing those 2 things I had no more rattling problems.

I had the same problem with my exhaust after I had it installed, it was because one of the hangers wasn't right.
