Y-Pipe Trouble
Y-Pipe Trouble I had a g2 y-pipe 2.75 diameter installed and it is making a stutter clatter when I accelerate on my 2001 trans am. When I floor it, it goes away. It is connected to the borla catback. Before I had it installed I just had the borla catback and it did not do it before. When it is idling and I rev it up it stutters a little bit. I took a look under the car and when I rev it up the pipes wiggle a little bit. The y-pipe was bolted on. Please help!
The y-pipe is probably banging on the floor board on the drivers side. Do you still have the stock exhaust manifolds? Check for clearance above the y-pipe, make sure you can fit 1-2 fingers between the y-pipe and the floorboard. If that doesn't fix it, then you need to find out where it is banging and place a heater hose or a power steering hose between the two.

What kind of clamp are you using to connect the y-pipe to the i-pipe? I had to use a band clamp to secure my Magnaflow i-pipe to my stock y-pipe because it would move ever so slightly and make an annoying buzzing sound. Not sure if this the EXACT thing you're talking about, but it wouldn't hurt to check it.
The way that I figured this out was that I had someone sit in the car and brake torque it up to about 1100 rpm. That was where the buzzing sound happened the most. Then I pressed up against the driver's side of the y-pipe with a piece of rubber. It stopped the noise.
But if it is that the pipe is hitting the bottom of the car, and you can't adjust it out, my advice is to get poly motor mounts.

Hey Keenov, how'd your TSP duals fit? I had to adjust mine twice, and even when I got the right amount of ground clearance ( Mine have yet to scrape ), they still hit the bottom of the car.
I fixed it with polys though.

Some speed bumps get me too. I try to avoid most of them.

I agree no one needs to sit in the back. The speed bumps are hazardous.
