Insane Decel Popping W/ Ivans
« on: January 21, 2021, 07:28:52 pm »
Hey all, had Ivan tune my ECU a while back and everything was great. Got a new exhaust (still a 2 into 1 like before) and the popping on decel and backfire is insane. Every time im off the throttle firecrackers are going off, lol. I don't think its a tuning issue since I had Ivan tune my ECU, rather I think there are leaks in the fitting between the exhaust and the engine fitting. The exhaust is a Dean Spead BZKR. Should I be replacing my old gaskets with new ones, is there some other product I should be using to get a tight seal? Any and all help appreciated, thanks!

I'd be installing new gaskets.  I addition, here is a video that help you in the installation:

Did you use sealant at the pipe joints?  O2 sensor plug in place?  Maybe try tightening down the exhaust flanges a bit more.

*Update*

Removed exhaust system, put in new gaskets at the front and year, secured it more centered on the exhaust flange, no more issues.
