I went with the Pace Setter shorties gained about 5 hp not gonna lie. The MPGS went up alittle bit. Those combined with the Magnaflow Hifolw Cat and the new Bosch o2 sensor and the cold air intake. Probably gained 10 hp total. I spent a lot of money for that little of a gain but I am impressed.

 

Do you have a dyno readout to prove these gains or is this just speculation of the butt dyno?

 

No dyno but I know the power differences in my truck been driving it too long.

 

cood update ! i love my longtubes def a diffrence in power for me !

 

I got a pair of Pacesetter shorties for free and had them JetHot coated. I think the headers are mostly for looks than any power gains. I could not tell a difference.

 

With just shorty headers, the Y-pipe becomes the next major restriction.

 

are long tube headers still able to work with the cat ?

 

+1 to Overstreet. I was looking under there yesterday. I don't see how long tubes would work with the transfer case and all on that side.

What aftermarket Y pipe are you guys recommending?

 

If you don't have emissions testing, Jegs (and others...) offer an "off-road" y pipe, that flows MUCH better than stock. (no cat.) If you have to have the cat, get a single in, single out, and splice it in there. (y-pipe has provisions for pre-cat O2)

Still need to run all the exhaust down the passenger side. I haven't looked real closely, but, I don't think there is room for a pipe down the drivers side...... and I hear rumors that having the O2 in just one pipe causes some issues.

 

Long tubes wont work, there would be too much heat on the tranny and transfer case. The stock y pipe dosent look like much of a problem to me. Its no different than a aftermarket setup. I coukld be wrong though. But I am happy with what I got it works for me.
