Y pipe banging How many of you with longtubes and a y-pipe set up have the issue with it banging under the car. If you dont have it did you do motor mounts to cure it or just no problems with it? For all what is your setup(brand lt's, y-pipe, and catback). thanks guys.
edit: another question r u m6 or a4 and could this make a difference?

I have pacesetter long tubes with a catted TSP y piped. The banging was driving me insane... to solve it I just shoved a handful of bronze wool in between the floor board and y pipe... hasn't banged once since =D

I have kooks LT's w a custom Y w dynomax bullets. The Y-pipe bangs on hard accelerations and sometimes when I'm turning into a parking lot or something. I've been meaning to shove something in between the Y and floorboard. will poly motor mounts fix the banging? maybe I'll have to get some.

My QTP Y-pipe banged. I had SLP SFCs under the car which made aligning more complicated. I ended-up loosing a cat', so I cut both of them off, hung new 3-inch round cats after of the collectors, got some 3-inch mandrel bent pipe, cut a section to connect the driver's side to the merge collector, and had it welded-up. I ended-up trimming a small section of the floor crossmember above the cat', pushed it up, stuffed a Mufflex hanger in there, no more bangy-bangy.

Poly mounts are 50 bucks and they're cake to install with the headers/manifolds out of the way. I did them when I put in my long tubes because I didn't want to screw around with a banging exhaust. Had my TSP ORY, true duals, and now a Pacesetter Y all tucked within 1/2" of the floorboard and it's never made a sound. I don't understand why people will do headers and then take their chances of having a Y pipe cranking their floorboard by not doing motor mounts.

Peacesetter longtubes, custome catted Y, and magnaflow catback, Y pipe banged like a prostitute. Poly motor mounts put her in jail and stopped all the banging!
