Our KRX 1000 added a mbrp muffle and new muffler gasket and and did reflash,and we are still have backfire when deceleration. Does anyone know what the problem could be????

Who did your tune ? I drilled out my cat and a tune I’m also having backfire issues. Mine also appears to be running lean looking at the inside of the tail pipe.

Alba racing did the tune for the slip on muffler.

Have you found any fix to this? I also added the MBRP muffler. Sounds like a 12ga shotgun went off sometimes

We didn't find a fix...we ended up putting the stock muffler back on,although we have been checking with friends and shops to see if anyone has found a fix,thus far nothing.

I asked the Dyno jet guys about this back fire condition that many complain about after re tuning there ecu.. has to do with the ecu in a closed loop at lower rpm and didn't indicate much could be done about it.. I went with the HMF and dynojet and have no back fire issues..

I have the hmf exhaust and the aftermarket assassins tune and been getting backfiring like crazy

I have a trinity slip on and a VFJ tune . I get a little popping but not bad.

Have a trinity slip on same issues, trinity sent tune a bit better but still there, stock back on because no performance added just noise, at times on trails too much noise.

Solution= Revert to stock. All problems solved.

I have the trinity stage 5 in black. I like it when the big girl talks dirty to me.

My bud has the full Trinity stage 5 and also their tune and pv3 sold through them. He still gets some backfiring. I think people will never get fully rid of it. But without tune it's terrible. Tex, stainless or black? Sell it... maybe even to me, though I want the full stage 5.

Black but I still slip it on in the dunes little noise never hurts there. 😆

 

[TexomaScott]

You probably already figured I'm cheap and you'd have to sell it for $250 before I'd buy. You'd rather throw it in the trash before selling to my tight ass.

Ha I'd sell it but we have Little Sahara Dunes about 5 hrs away and a weekend trip, 20 minutes and it's on and sounding good for the Dunes. Stage 5 sounds good in the dunes.

Lean condition causes the backfiring. To help, make sure ur fully off the throttle when deaccelerating. Just a touch of throttle will send fuel thats too lean. PV3 tuner and u can fix that.
