Exhaust decibel pop

So we all know the SS exhaust pops and of course the pop gets louder with an exhaust and then louder with headers. I am really not bothered by it.

Anyway today I changed the check valve connector on my RX catch can to a non check valve connector and I noticed the decibel pop is now gone.

Does that make any sense and yes, why?

It's weird. I did not change it for that reason, but I like the fact it is not gone.

Thats weird because most of the decel pop is from DFCO (Deceleration Fuel Cutoff)

I don't know, I guess we'll see tomorrow after it sits for a night. But all day today there was nothing.

Like TECADON said, decel pop is a function of DFCO. Not sure why you would experience any change after messing with your catch can.

I'm thinking that the same people who like a muffler delete would also like the poping.

Nyrfan,

You could try putting the old check valve back on to you CC and see if the decel pop come back.

If you don't like it, you can have it tuned out (as it is on mine).
