3800 flex pipe

[Ricky Gonzalez]

is this flex pipe only there to convert the 3" exhaust flange to 2.5 pipe before the Cat?? i know it can allow the engine to rock like 6 degrees or something like that. i was just wondering because my flex pipe broke and i just welded a 3" pipe off the flange to the stock downpipe. didnt know if that will be a problem. if anyone else has experianced this what did u do and what was the result??

I ran a solid DP for a couple of years, didn't have any issues. It may transfer more vibes through the car though.

no exhaust leaks?? any thing like that? CEL come on?

just run open exhaust manifolds and remove all doubt!

Exhaust leaks generally won't set a MIL, only if is skews the H02s readings; and you could always pop in a 02 spoof to fix it.

The DP's I've built for people are done on the car, so it's built to application. Generally though if you are unsure on the fit, remove the upper motor mounts and torque down the flange from the DP to the rear mani and it will seal up fine. I've seen a few leak from re-used gaskets though.
