let of the gas and today i had to have my OEM exhaust put back on just to rule out the possibility that it was the cats or something (its the Borla). I missed the Borla rumble and extra power immediately and forgot how quiet the OEM exhaust is. Borla said they would send out a replacement so i hope i can get it back on the car soon.

 

Good customer service on Borlas part, do you have to send the old one back?

 

I'm sure they'll want it back, they wanted that incorrect muffler portion last time I went through this. Took them 2 months to send me a box though.

 

Can u describe the sound. Was it like a grinding sound or rattle sound.

 

like a rattle when you would let off the gas, sounded kinda like peddling backwards on a bicycle and the sound that the bike chain would make but super loud

 

Hmmmm.... I may have the same situation with my exhaust system. Does it only happen when the cars warmed up? Does it also happen when ur shifting gears?

 

you can hear it better when the car is warm because the exhaust tone is more mellow but its there even when its cold. I wouldnt know about shifting because i have an automatic
