I just got a new exhaust on my car. And when i drive at about 3500 rpm theres a vibration/ rattle sound coming from the back. I checked out the piping and everything has good clearance. what could the problem be?? PLEASE HELP!! ITS BUGGING THE HELL OUT OF ME!! thanks :evil:

 

I hate to say it, but if you have a loud exhaust, there will be some things that tend to rattle.

I have a friend who put on a Greddy Evo, and we took off many things in hos interior, and got most of it to stop, but even still, It was annoying as shit.

the one we couldn't get to stop, and the only one that was very noticable, was the one coming from the back pannel, not sure what it was, cause we got tired of looking, but you may want to start there, also make sure all your tools, in the spare tire well are secure.

When and if you find out what it is, please, let me know.

Later,
Aj

 

Hey Thanks AJ...My friend with an s2k had the same problem with his exhaust. He got it fixed some how. We are going to look at it this week and hopefully well figure it out. Ill keep you posted.

 

What kind of exhaust did you get? Axle back? Catback?

There could be many possibilities.

For an axle back system,
Did you use the stock donut gasket?

Catback system,
Heatshields could be rubbing the b-pipe.

 

I have a HKS Hiper Universal Muffler with stock s piping. I am using a flange or dounut as you call it off another type r (didnt want to cut mine). Same bolts just differnt axle piping. PLEASE HELP!! IT IS VERY ANNOYING!!

 

Check your heat shields that run on top of your piping. When I installed my Apexi N1 cat-back exhaust, I heard something rattling underneath. I jacked up my car and found out that the heat shield was touching the pipe at one of the bends. I simply just bent the heat shield a little, and the sound was gone....

 

Oh, and another thing I forgot to mention. Check your hangers too... :wink:
