Exhaust Pressure

[julycover96]

What are some things I can try to do to relieve exhaust pressure?

straight pipe it or get a new exhaust

Take the turbo off and straight pipe.... Absolutely no restriction then!

Seriously though, on your truck trash the cat and muffler and run a 3" downpipe and 4"straight pipe....The dowpipe is aggravating to install, but once you remove the stock one you'll see how restrictive it is

Ahhh... and what brand is best and where is best place to buy? I want it LOUD!

Probably be best to talk to one of the vendors here on the site.... Gus from Farmboy Diesel is a cool guy to talk to and he has some budget deals usually.

I'd be careful buying from any ol' Joe Schmoe website. I had some major problems buying my exhaust from rpm outlet.... Took almost 3 months to get my sh*t....

Can't go wrong with the site vendors though

bigger exhaust housing for your turbo

[Tikal]

He's probably better off starting with updating the downpipe....

Turbo work usually isn't constituted until the injectors are updated.....in an OBS anyways

Definitely NOT a bigger turbine housing on a '94-'97. If anything especially with stock injectors going to a smaller like a .84 would be the best for performance. With some very mild injectors a 1.0 housing.

Best things for flow is a down pipe and exhaust. I would recomend Hypermax for the down pipe because it starts at 3" then after the firewall goes to 3.5 and has a 3.5" slip on the end so you just put a 3.5-4" adaptor on it and then you are 4" all the way out. And it's only like $130 which is one of the cheaper ones you can get! 4" exhaust you can either build your own or buy it. Either way works fine.

i agree with gts. the OBS trucks come with a 1.15 housing stock. man i hate to think of the lag with something bigger

the down pipe would be a very good place to start then gut the cat.the stock exhaust is good enough for stock to stage1 injetors on the OBS trucks.not like the SD.
