When I rev-match...I sometimes get a popping noise from my exhaust when I let the clutch go...is what does this sound mean? is it harmful?

 

uh oh... the dreaded noise...

 

How are those AFR's?

 

does it sound kinda like a backfire?? mine does that too i dont know what it means though, it started happening with me after i went with a catless tbe

 

Yea it does...like a detonation...I think when I rev up real fast...maybe it's too fast and I havent given the engine enough gas or waited too long to shift into gear

 

make sure you clean out all the pop corn cernels out

 

defiantly gay

 

wtf? MDSevo06 is right. Ah and thanks for the constructive advice

 

sounds like normal backfire to me. Are you tuned?

 

Yeah...I just think I might be letting go of the clutch late after I rev up...maybe I hadn't given the engine enough gas to work at the revs that I needed it to...I dunno

 

Rich tune... Unburnt fuel hitting a hot spot in the exhaust somewhere and making a "pop" sound. I still get them during partial throttle custom flashed.

 

probably a backfire

 

Now that does make sense to me...I knew I was running pretty rich...so I really didn't think I was lean

 

+1

 

I wouldn't worry about it. It is just a backfire. Does it only do it when you rev match or does it do it at the end of hard run too? It is pretty common during rev matching and it is just a matter of how loud it is. Most likely during that transition get overly rich and ignite unburned fuel in the exhaust.
