Pacesetter Y-pipe
LOTS of people have this problem with the PS Y-pipe... that's why most people you see with PS LT's are running a differnt Y... usually TSP's. One person in particular that had this same problem was 01TA - maby he'll chime in and let ya know what he did... wasn't a total fix but helped a lot.
just a little, but its enuff, I got TSP y and love it Trending Topics

cut the hose down the middle, find where the Y is banging, open the hose & get some small screws & tack it to the car... ( undercarriage ).. Very Easy, cost efficient & NO MORE BANGING...
worked for me..
The inside of the Y pipe needs to be ground. Here's a before, sorta, I had already started grinding before I thought to grab the camera.

After:

Despite having the Mufflex hanger I had a really hard time getting the TSP Y pipe aligned just right, it was still making noise at wot. After alot of frustration I finally took the car over to Speed Inc, they re-adjusted and it hasen't made a peep since. It took them all of 10 minutes.
