OK. I have a Mac O/R H-Pipe that is just too loud for a daily driver. If I don't sell it, would swapping the Mac H piece the mid-pipe with the stock do anything if at all fit?
i think he wants to know if putting his cats on that midpipe would take away from performance.......
dunno, thats how i interpeted it
+1There is not realy any performance gain by just changing out the H-section. Its the stock cats that will kill the power. you could go to a catted h-pipe, they come with high flow cats. and are quieter. But if you are gonna use the stock cats you might as well put the stock mid pipe back on.
