Re: 3" DP Pics?

I have one, just not in the truck yet. had a local exhaust shop bend it for me using my stocker as a jig. Not mandrel bent but was only $60 or so. I made a turbo flange to fit my 20g. I will prolly piece it to made future removal alot easier. I did a half ass mock up when I rebuilt my engine and i believe I am going to have to dimple it in a few places to clear a couple things. Once it fits nice I will paint it with header wrap silicone paint and wrap it. Don't know if this helps at all, figured I'd throw it out there.

wideband should be 24" from turbo max.

Your pretty limited on design, your turbo location is set, and you have to go between the frame and bellhousing. Watch that you dont come too close to the plug wire boots. Also, plug wire #6 is a straight boot (what most people run) so make sure the downpipe clears the straight boot and wire. Bring it down between #4 and #6 cylinders. Like show above. Its easier to do work with a 2 piece dp. I made mine 1 piece, and it takes some wiggling to get it out. If you are running A/C, you are really limited.

Also, you have to worry about wastegate location, servicing the wastegate, etc.

Good luck.

Eviltwin runs a one piece 4" downpipe and it's very easy to remove, but with coil packs you don't need to do as much maintenance.

Ok, thanks for replies. Not sure yet what to do with A/C. It's not working, some previous owner took off dryer can and hoses.
This is what it looked before with 2.5" dp...
