Vibration after test pipe install
After installing my test pipes I am getting an intermittent vibration in the gas pedal/floor board at WOT in 1st gear only. I think the engine is torqueing a bit and things are rubbing although everything looks good when static and I don't see any obvious marks.
Anyone have a similar issue? Should I just start pounding away on the heating shield with a mallet? |

Did you do the install yourself? Get under the car and flex the exhaust front to back. You will find if it is hitting something and will get your answer.

I did do it myself and made sure to replace the gaskets. I'll try to get under the car again this weekend and wiggle things around.

Check the heatshields after the header flanges on top.

I had a slight vibration on mine a week or so after install. It was the clamp that holds the TP to the X Pipe. Simply needed to be tightened a bit more after the initial install, and the vibration hasn't been back since!

I feel that in my gas pedal too. I suspect it's the lack of that bracket that connect the x pipe to the tranny that you have to cut off.

Remember that the exhaust will expand and its positioning will be slightly more to the rear of the car when it is hot. Make sure you have adequate clearance all around your test pipe clamps. They may have to be reclocked.
