Pop
 

Not sure if this has been discussed or if anyone else has had this with the car but...When I first fire it up...there is a pop...or backfire once the rpms drop after the initial startup? Any ideas why?

:iono:

My mustangs both did that. My 07 gt was real bad about it. The camaro doesn't do it as much, resonators and all kinda muffle it I guess. I honestly don't pay it much mind anymore. It's just the backpressure hitting the fresh exhaust gases coming out the headers, making a pop when they meet. At least that's how it was explained to me.

not sure why but it sure sounds good with my muffler delete.

Same here!

I get that every now and then, but not always. I've been told that it's normal, and it sounds cool.

Well Crap!!! I guess thats my next mod....because it sure is embarrassing with stock exhaust. lol

I don't see a problem??

My car doesn't do it on initial start, but if I start her back up after a drive she will pop. I find it an inviting sound. Then again, with the THR pipes, I backfire just about any time I get off the gas. I really like it.

Its completely normal for large displacement motors. I infact LOVE that sound. It gets even sweeter with a CAI and exhaust!

I guess this decel popping happens on the L99 too, just not as much? I've noticed that if I accelerate quickly (like when I turn off my street onto the main road) and then let off the gas after a second or two, I'll get some pops.

Yep my L99 does it alot with an intake and stainless works Retro chambered exhaust. I love it. I drive using the tap shift so I can down shift and use the engine braking to decelerate when coming to a stop. Love the sound.

Sent from the rocket in my pocket, my all powerful DROID BIONIC.

After putting the new exhaust on my six, I notice it every once in a while, actually.

I kinda like how it sounds :wub:

dig the pop!

NORMAL!!!!
