Y-pipe for N/A trucks

[wbw189]

I had an email reply from Auto-Jet today. They are still carrying the 3" Y-pipe for the IDI motors for $129 + shipping. I am thinking this plus a PSD takeoff exhaust as a decent kit.

Have fun,

That seems expensive, I had one put into mine to get rid of the factory tee collector, and it wasn't near that much. I agree with you though, a true Y with a larger system makes a good exhaust.

Sweet, didn't know this was available.

Have one on my truck (the y pipe) and have had great luck with it. Fit well, functions well and seems to be holding up well. Just an FYI, the down pipes are NOT 3". They are large, forget what size now, and were substantially bigger than what was on my truck (had true duals when I got it, made of like 1 7/8's pipe). Anyway, has worked well for me. Kind of hate to take it off to turbo my truck when I get to that point.

Mines holding up well, too.

Mine is holding up well also.

Thanks for your feedback. I think this is worth my time versus trying to fab the same. I keep fixing a bit at a time and I will have a new truck.

Does anyone know if this will work with a PTO truck? I want more power and fuel mileage for the rollback and I have a PTO in the factory exhaust routing location.

And here I sit wondering how the heck I still have the original exhaust system on my F250 from the manifolds, to about a foot behind the cab! Past that I had to replace twice.

Did any of you N/A guys notice a good difference in power with a new, bigger exhaust and Y pipe?

I do plan on a 3.5" stock style exhaust system when I restore my 1990 F250. Won't be adding a turbo, ever.

I'm not sure I'm a good one to answer this as my truck was about like using straws for exhaust with the small true duals, but for me, this was one of the best things I ever did power wise. I also saw a huge drop in EGT's, but that's to be expected after trying to push all that exhaust into such small duals.

I noticed the AutoJet system right away. My NA truck will prolly out run a 460 to 50 MPH.

i had an aftermarket 3" exhaust on my truck when i got it and i had a good bit more power when i cut the muffler out and put a 3" 90 on and made myself a side pipe . sounds just like a jake brake when you tach it up to 2500 and let off fast, downshift going about 2000, or just coast down a steep hill

ill soon be doing true duals with 3" pipe from the headers back into 2, 5" turnout stacks laid down along the bottom side of the cab for side pipes

 

[IDIDieselJohn]

Yeah that's what I wanna do, run straight pipe, but factory style exhaust setup.

I like the sound an N/A diesel has straight!

 

[MidnightBlade]

kinda makes you want to make up an excuse to go to the bathroom dont it?

i would just do a side pipe right behind the cab, save yourself lots of pipe and lots of bending.

 

[IDIDieselJohn]

On any other truck, I would simply dump it right under behind the cab, since it's a diesel, it be best a side pipe. But for this truck, I wanna keep it as original as I can, also keep the original style and look. So I have to go over the axle and out behind the wheel.
