Well, I bought an AFE filter from Merrick, and stole some exaust piping from him. It's REALLY loud, high ideling at 1,500rpm gives a very, very loud whistle, more so than the stock truck gave at 15psi.

Looks pretty good

Hey nice work! you might want to cut that tube a bit shorter to reduce turbulance where the rubber elbow makes the 90*

John Rodriguez

I plan on it, it was just a sort of "cut... oh right about there" type of deal. But I'll probably take out the 5" and take off 1.5" and paint it black today.

Looks good, so why paint it black? Seems like black would absorb more heat.

You need to put a heat shield between the turbo outlet pipe and that filter .... compresssed air makes alot of heat ... that's why it feeds an intercooler.

If you do cut it like in half, I'll take the other section off your hands... ...I have been looking to do this but cant locate that size pipe anywhere.

John Rodriguez

You should be able to get it at any muffler shop, or at least, a big-rig repair center. I'll tell you this though, that's a 5" pipe, you need a 6" pipe for stock fitment on the elbows. I just cranked the clamps down with a cordless drill and tadaa . If you really want a peice, I think the shop has another 2' of it left I'm sure they'll let you have for shipping costs. Lemme know if you really want it, I'll ship it to you

That's very similar to what I'm planning to do except I'm going to use a BHAF instead of an AFE filter. I also plan to build my own "torque tube" with some 4" intake tubing and some 90 degree elbows.

HdPower, you can get everything you need at Air Flow Systems. They're kind of expensive though.

By the way John, that pipe you have looks more like a 4" pipe than a 5" pipe. The stock plastic piece that fits in there is 5".

Thanks JR...I will check with the big rig places down here didn't even think to look there ,and by the way I do appreciate the offer.

I'm a little confused (easily done) do I need to look for the 5 inch pipe or the 6 inch??

And Hoss, thanks for the link...there are a couple items I may order from them (clamps, hoses) .

Hoss

The factory plastic piece is 5". I don't think you could get the elbows to go around a 6" piece of pipe.

You need something like THIS , but I'm not sure this particular one is long enough. I think you need a length of about 8 inches.

John Rodriguez

Sorry about that guys, it must be that great pain medicine I'm taking for my teef

nickleinonen

the factory piece is 5.5"od... 5" exhaust pipe seens to work, but that's asking a lot of the rubber elbows to "shrink" down 1/2" to seal well...

Hoss

In that case THIS is what you'd need. I could have sworn I measured it at 5 inches, but I must admit that I did this by eyeballing it against a tape measure. I didn't take the elbows off and actually measure the true diameter.

If that's the case, then maybe the pipe John used IS 5 inch pipe...and he just needed 5.5 inch pipe.
