I just went from having a test pipe to the road race rally cat and I was very happy...now the bolt underneath doesn't hit my catback anymore and rattle but now I hear more rattling I think from the heat shield on cat to the heatshield gaurding underneath the car....am I going to have to live with this or can I somehow adjust the exhaust? Anyone else experiencing this!!!? Its worse when I turn the wheel to make a turn and gas it a little....thanks

 

I just put my leg under the car and inotice a lot of play in the exhaust...like I'm able to move it with my foot quiet abit it that normal or should it be solid in one place?

 

weld it .

Please do not weld your foot.

 

My main question is...how much play should be in the exhaust....a lot or a little? It literaly sounds like my exhaust is falling off.

 

the build tolerance on the rally cat could be off a little bit. And this can cause the exhaust, rally cat to rattle against the heatshield or rear diff area.

 

thats too much play check the bolts and increase length if neccesary

 

Take the rally cat off and give it a few shakes. Something might be loose inside.

 

Also, Kart Boy exhaust bushings work wonders. My aftermarket exhaust is heavier than stock (2 silencers) and the stiffer bushings help it from dropping/rattling.

 

Well thing is...before I changed the test pipe it was rubbing against the bolt and vibrating..so now there's major clearence and I was all happy thinking wow no more noise...but now I'm getting wayyy more....:[ what should I do....

 

Btw it seems like it starts making noise once the car gets hot.....

 

Call up RRE maybe you have a bad rally cat.

 

My RRE 'rattle'-cat was making a god awful diesel tapping sound at idle and moving from a stop.
Took it off and noticed the inner resonator pipe came loose. Shaking it you can really hear the rattle.

 

i just got mine put on. it does make a little rattling.
