Exhaust question

[6.5SmokeStack]

OK heres the questions, does the exhaust flow better going through the regular exhaust pipe under the bed or up through a 5" y pipe kit to 5" stacks? Because I was thinking of doing the exhaust from the new turbo down pipe to a turn out before the wheel

If the exhaust ends under the bed or in stacks seems to me equal, but there's no need bigger than 4" in diameter. The important thing in exhaust is the downpipe. The factory one looks like a truck rolled over it. Get a aftermarket 3" downpipe and the rest as you like.

That's what I did for mine. It dips down under the gap where the frame arches up for the front spring shackle, then another 45* brings it out about 9" in front of the rear tire. No muffler! PM me and I will give you the Heartthrob #'s for the down, front extension, and the 45* els. You can have Walt order for you, he's a Heartthrob dealer, or go factory direct. (I did the last in SS and polished it out. When I put a 4"-5" tip on, ka-bling!):D
