I just saw these. And there 2.5" collector with a tru x pipe which is better suited for the 5.3 I think. Anybody using this setup? Hows the fit?

 

I just checked their site. Dont see anything like that.

 

Stainless Works - 1 3/4" x 2 1/2" Long Tube Headers w/out Cats - 2007-2013 Silverado/Sierra 1500 - CT09HDROR | JDP Motorsports

Just one site I found but theres others. Looks like its made to order?

 

Scratch that, sorry for the misleading info. Found out their for a 6.2 and im about 99% sure its a different exhaust port :/

 

2007-2013 Silverado/Sierra 1500 4.8L/5.3L/6.0L/6.2L - Stainless Works - Long Tube Headers

Stainless Works long tube headers without cats for the 2007-2013 Silverado and Sierra 1500 4.8L/5.3L/6.0L/6.2L V8 features 304 stainless steel CNC mandrel bent 1 3/4" primaries, 2 1/2" slip fit collectors, welded o2 bungs, o2 extenders, and x-pipe with 2 1/2" off road lead pipes to fit the Stainless Works dual exhaust system.



Reading helps.


I would imagine that setup would work great.

 

I think im going to order it monday, or atleast talk to SW. It just seems perfect for the 5.3 but I havent heard of anyone using it.

 

Feel free to contact us with any questions you have! We're available by phone from 7:30 a.m. to 4:30 p.m. EST Monday through Friday

 

Not trying to sway you away from SW but have you looked at Speed Engineering as well?

 

Sure have! Running their headers now. Im doing an all out ( kinda) 5.3 build and Im not sure if 3" duals would be too big or if 2.5" too small. Shooting for 400 rwhp.

 

If you want peak HP then 3" duals. If you want more grunt down low, single 3". Even a single 3" won't start to be a major restriction untill well north of 400hp.
