I believe I fixed mine years ago by putting a poly engine mount bushing in on the driver side. No real noticeable drivetrain vibration in the car either. Improved throttle/driveline feel. I can't speak for replacing both sides.

I've heard that this works for some people. Others use Mufflex's "bump stop" hanger.

take a cheap U clamp from advance auto and run a piece of hose through it and and slip it on the pipe wherever it hits at. very cheap fix that works

Bunch of friggin hacks. Fix it right and replace the motor mount with a poly one. The Mufflex and homemade version are a joke.\\

Sooner or later the header itself will start hitting on deleleration as well as acceleration. You wont fix that with a mufflex. Do it right the first time and dont be a hack

I guess a piece of rubber radiator hose makes me a hack

What can I say, it was cheap, and easy to install. But best of all, It worked!

This is the same type of questions people post up after they can't get their car to drive decently after putting a big cam in it. It all goes back to lack of planning / not knowing what you were getting into. In the case of the cam-install, it's not budgeting or scheduling a tune. Here, it's not understanding that 3" pipe is going to interfer with the floor when the motor torques and NEEDS to be addressed.

If you want to put long tubes on your car, buy some motor mounts to replace your worn out rubbers stockers.

My Jet hot pipe was right against the floor on the passender side. I pried it as far down away from the car as I could and wedged a piece of wood between it and the floor to hold stress on it. I then used a floor jack on the opposite side that had too mutch clearance and twisted the Y pipe and retightened all clamps. After removing the wood, jack ect. I had a little over 1" clearance on both sides. This method also works on pipes that have all joints welded as it will still tweak the system just fine. Dont apply the stress right at the collector as you dont want to tweak the primarys of the header itself, only the Y pipe.

No need for rubber hose ect. and it will not dent or scratch the system if you use a block of wood, cardboard ect.

The poly dr side engine mount serves more than one purpose. Worth every bit of the $50 and my time to install. Then you can sell the other one like I did.

The banging on my pipe is driving me out of my mind... next time I'm home for a few days I'm changing them asap. Is it possible that with enough harsh banging the car will pull timing, almost similar to how some LT1s pulled timing without the LT4 knock module?

Change your motor mounts and save the exhaust money for something else.

Just twist the Y pipe to get away from the floor, it takes approx. twenty minutes even if your a complete idiot.

bumpstop and poly mounts = banging y pipe for me still. Catted Y.
My best fix: driving over random steep driveways that scrape really good...the kind where everyone in the car flinches. Yeah, those accidental occurances seem to work the best for my banging. I can go about a month before its banging again. At that point i look for something else to get stuck on. lol.
What can I say, I hate my TSP Y. I've had that thing off a million times readjusting and the only way i can get it to not bang is only worth a coke can on its side.

Goin with a custom 2.5" under axle true dual. to fix that problem.
