What long tubes you guys running on your trucks that are 4x4. I've heard that some of them have to be modified around the driveshaft etc. I'm looking at the Pacesetters and just wondering if they'd have to be bent any.

PS longutbes, had to slightly flaten drivers side of Y pipe. I have a 6'' lift though and the front drive shaft is dropped 5 ''. Other than that, no problems.
Tri Y Thorley headers. [ I know not a true long header ]
welded flanges on the cat bolted to collectors.
Cut up the stock Y moved it back about 1 inch.
Where did you get your Tri Y's, I wanted to look into a set of these. I heard you can get a lot more bottom end out of these over true long tubes. I'd rather have a lot of bottom end since i tow all the time.Quote:

Im running Pacesetter Long Tubes on mine. Plenty of clearance. I did not get the y pipe I had mine custom fabricated.
Dad gum it....I've heard the PS LT's won't fit SSS, Denali, Escalade AWD.

I'm going to put a hybrid sticker above or below my 6.7L stickers when I do them.
I put a Cam in about the same time. With both I dropped a second in the 1/4 mile with my Interceptor gauge.Quote:

thanks fellas.
I dont need the pump fittings either....you had to build your Y-pipe though? I could probably do that, but i want to try to keep my stock exhaust whole so i can put it back to stock if i need to sell it.Quote:

So your stock Y is beyond easy repair.
Stock is stainless--hard to bend etc--but should last.
Hope this helps.
that helps a lot! I'll get ahold of my salvage yard guy and see if he can get me a stock y pipe to cut up.Quote:
