I just installed the T1R headers and T1R test pipe,
I got the killer bee's pissed off!!! I don't have a catback
yet, I'm stock cat-back:

Now I have major noise coming from the headers, a sworm of killers
bees, at idle its silent. I have checked for leaks...

Should I add a hi flo cat, resonator to the test pipe?
or a small glass pack type muffler on the test pipe??

Performance wise, the setup is awesome, on a sport a/t fit. Good highend power, with no noticeable lost down low on a/t. Can't wait to get an intake!

thanks!
