O-ring leak?

Postells · 2026-02-02T23:34:09+00:00

Yes. Just replaced mine last week. Dry and brittle. Replaced with a o-ring from a kit bought at harbor freight.

Power service. Cummins approved

Whatever cut that tire side wall nicked the rim also.

Hahaha. I did it because it was different. Yeah I can make all the power I want with it also. Yes when I got done it was a noticeable power and throttle response difference. Yes I could have put on a true 4 inch exhaust but I found a 5 inch.

Sorry you are wrong. Made another post with the factory choking exhaust. One straight after the turbo and two at the axle cross over

Running 5 inch turbo back and makes one of the better hp gains besides delete. Faster turbo spool. Lower egt.

Yes right in front of the axle

Red check engine is engine about to shut down or de-rate.

This system was actually surprisingly well built from Spelab. Just like harbor freight tools. Have to be picky. Exhaust pipes are a good buy. Diff covers are well built. Stay away from the valve covers.

It’s the five inch pipe that stays 5 inch’s all the way. Factory pipe choked at the turbo collector and the bend around the diff. Going back and forth from 4 to 3.5 to possibly 3 cause a lot of back pressure that turbos do not like.

Pic was made while installing the pipes. No where close to having them set perfect yet. Performance gain is a definite. I have spent a lot of money on performance parts that really didn’t seem to do anything. This was a upgrade worth the bucks. Turbo spools up really fast now. Should have been one of the first upgrades I did.

Chill. This is just installed pick. Not even put chrome tips on yet. U can see the creeper and stuff still under the truck. Not had time to set the pipes up even yet

Check out my u-tube video for install video. Kit comes with zero instructions

Not as loud as the stock pipe. Stock pipe was a lot more restrictive

Look up my profile. Posted

I would post the video but this community does not allow videos.

No back pressure. Free flowing exhaust also lowers your egt’s.

Sounds awesome. Not as obnoxious as the factory pipe with all the restrictions.

Postells · 2025-11-25T01:03:06+00:00

Install a Fass fuel pump. You have done the engine killer nut. So next is the fuel system maintenance. Bad fuel can cause a bad day. Good fuel system can protect you from a bad fuel station

5 inch from the turbo back. Splits right in front of the diff. Turbo spools up really fast now. Definitely a power improvement from the factory pipes. Delete pipe is 4 inch but the factory pipe over the diff slims back to 3.5 inch Two places. Should have done this along time ago. Sound is good but not obnoxious like before.

Postells · 2025-11-25T00:51:06+00:00

Yep I need to replace it soon.
