Up pipes and manifolds
 

Looks for a set up for exhaust manifolds and up pipes add a lil horse power and torque lower egts maybe a lil quicker spool up just your guys experice and reviews wat you liked how'd it work with your setup??

Sinister has cool looking ss up pipes with slip joint instead of bellows, wondering if anyone tried em?

I saw some steed speed manifolds that combined with a matching set of up pipes suposley adds 92hp and 110 lbs tq but it's $1100 just for the manifolds n prob 500-600 for the up pipes not worth it in my book

I've got them. They are nice. Welds are done well, look like they will flow a whole lo better than OEM. Very hefty and great quality. I haven't noticed any gains though. And from what I read some people have no problem installing them, others do. I had issues installing them. If I ever did it again. I would make sure the pipes are pulled out as far as the slip joint would allow. I had issues with the pipes not connecting to the manifolds. Seemed to short but I got them seated after messing with them for a while.

I see sinister now makes a cool looking stainless header setup for the 6.0.:jump:
