Hey guys, Just wondering if you guys are getting any backfire or popping noise after deceleration with our cars. It didn't do it before with oem exhaust, just wondering if we're going to get a little bit from my new joe z exhaust, or do I have a leak somewhere with my installation. Or do I just need it break in a little more. How do I check for leaks , Do I just need to ramp the car and check all the flanges for where the exhausts bolts up and check for alignment issues. Thanks

You should not be getting any sounds like that during acceleration no matter how light. If any, only on deceleration.

oh, sorry I meant deceleration. my bad, I'll correct the original post

its normal from what I have read. I have a new Joe Z system to and noticed a slight pop today as I slowed down at low speed. I ran with a new Lambo Hurracan a few weeks back and his stock exhaust was popping like crazy when he slowed down.

I did a muffler delete 2 yrs ago and still have it and mine pops when I let go of the gas it doesn't do it all the time but yes it does do it.

It's normal.... Especially if you have an exhaust with headers it's more noticeable

Yes, my exhaust and headers crackle and pop a lot under deceleration (in manual mode).

Popping noise is normal. My is350 with f-sport exhaust did it as well.

Yup, mine does this.

It did it before when I had headers and OEM exhaust.

Now with Headers and JoeZ it more noticeable....and I like it

Normal under deceleration and especially noticeable with the JoeZ. Like others have said, I like it.

once I removed the secondary cats, I noticed it. When i just had the hks axleback on it's own, it never did it.

You can make it pop if you notice when it comes on.

For me its basically drive, 1st-2nd-3rd gear and then let the car decelerate while holding 3rd gear and you'll hear a nice pop once the rpms are low.....Love it
