down pipe

I made mine out of two 4 inch 90*s

how hard was that just the 2 90*s and a piece of straight 4" and how do you connect it to the hc1?

I 2nd gen one will fit with minor "tweaking" of the firewall... And by "tweaking" I mean hitting it with a hammer....

If you are still running the H1C I would not waste my time or money on a 4" DP. The aftermarket bolt on 3-3.5" pipes are more then enough.

Whats up Tbone! Aint been on here for a few. And i agree with not needing a 4 in if you got a stock turbo.

I just welded it to the factory flange.

Check out Diamond Eye, they have turbo back 4in kits.

I have a 4 incher on my truck that will be for sale soon. How quick do you need it?:rocking:Rocky
