hmmmmm...again....

it makes sense what youre saying...but i dont understand why it's happening to him?
as for the borla exhaust...i know nothing about it so i cant say anything about it. is it true dual? or a ypipe back (do you still have the stock ypipe?)

its the true dual on my 04 coupe cat-back and when i put the tp on the sounds made me go ahhh. i just went out side and reved it a little and stuck my head under the car and its a wierd sound. like air with a little squeek at the end when the rpms are falling. but right now im running the factory system with factory Y pipe. but with the borla there was still a wierd noise

i wonder how much worse it is...id like to hear that in person...
i guess ill just have to see what's up after i put on my HKS
if that doesnt help...i think imma switch to crawford
and see if that helps...i have a friend with crawford cats and no symptoms like this...so if i ask nice enough maybe he will let me experiment with his crawfords...

I put it on the lift at work everything is tight, and its only coming from the drivers side. Any suggestions on what it could be?? 
Stupid Question lol... What the hell is this mod. Ive never heard of it

haha ya that would be nice of him, definatley nice to hear things in person i really wish i could have my stuff in cali for a few days but im in NC so getting things in person is kinda hard out here but i have been wondering about other pipes or cats also. i was thinking to switch to your cats first but if they have a problem too then im not sure wat to do i thought it was just the tp but if anyone figures this out please let me know(Rick if you find something pm me please) thanks
