ok so i recently sold my 3'' dp. and now i have a CA header i'm going to order the 2.5'' dp with high flow cat, and now i need to know which exhaust to go to. magnaflow, or gmpp? keep in mine the gmpp is a 2.25'' exhaust and the magnaflow is a 2.5''. gmpp sounds so tempting due to price.

 

Magnaflow. I don't like the GM stuff too much, though stage 2 pwns. I would go Magnaflow.

 

neither go custom, its way cheaper

 

X2!!!

 

i say gmpp. good stuff. not too flashy and simple.

 

just for reference i had mine custom made.

my custom catback ran me less than 250 total parts and labor. 2.5'' catback with dynomax ultra flo muffler and dynomax ss resonator.

and for bragging rights i got my DP used for 140 shipped, and my GMPP manifold for 160 shipped. $550 full exhaust FTW

 

My pacesetter header was $168. My custom 3" exhaust was ZERO!!!! (My dad does business with the muffler shop )

 

So you think we should go and get out own custom cat-back exhaust? How long does it take to make and is it the same quality as any aftermarket cat-back?

 

I have the GMPP exhaust and love it.

 

I've got the GMPP and I love it as well. After a few hundred miles the sound mellows out, and it sounds great.
