i haven't been able to get a sound clip of it but i'm getting this sound in the low end that sounds like the exhaust is back firing. It happened after i re-installed my headers. anyone know what might be the reason?

 

youhav eno cat right there is no back pressure..does the sam ething with my alphawerk and my exhust i personally like the sound its sweet...

 

Yeah I get the same thing. I also have one 14" resonator which is too small for the custom catback I have. But its a normal thing.

 

i get the same thing with only an injen intake and HKS axlebak weird but i like it...

 

LOL i like it too feels like every once in a while im putting out fire haha but yea i was just making sure its not a bad thing.
