Hello All,

New to the forum but just recently about a month ago got a great deal on a 03' Track with 60,000 miles on it. Car was serviced and taken care of however there is an odd vibration. The car is relatively stock, i added a short ram intake, exhaust is straight pipe with aftermarket exhaust, and solid motor mounts.

When driving i get a vibration on deceleration at different RPMs. Its always the same RPMs tho, 2250, 3000, 3500. This happens regardless if the clutch is engaged or not and still happens if the car is just parked and revving. I have changed fluids and I am still not sure what it could be. Any help or advice is much appreciated thank you!

 

Solid motor mounts = bad idea #1.

Straight pipe exhaust = bad idea #2.

 

So than I assume you recommend replacing exhaust with something with a resonator or high flow cat. As far as engine mounts would doing the z1 urethane mounts be better or should I go back to oem.

 

Sorry, no experience with the Z1 mounts, but I'm sure if you ask them, they'll be honest about how much vibration you might expect. There is surely nothing wrong with using the original mounts, though, and they will transmit the least amount of noise/vibration.

As for the exhaust, I'd look for a complete system, with resonator, and do some research. Some systems, even with a resonator or H-pipe/X-pipe will still have some drone, while others won't.

 

Thank you for the advice I'll try it!
