Last week I got a TurboXS catback put on. It sounds great and I really like the look and sound however I hear rubbing or slight rattling esp when I'm in low RPMs (and exhaust shakes) or when I first cold start the car.

I have the exhaust mounted pretty solid, all the flanges are flush, but the sound appears to be coming up from the front. I'm maybe thinking downpipe rubbing against my aftermarket lower arms? I thought I checked initially for clearance throughout the exhaust.

Any one else with thoughts or ideas?
Anyone else with the TurboXS catback with any input?

Thanks in advance.

 

I have the TurboXS full turbo back and have no rattle at all. I did however have to bend the underbody braces to clear the new dp.

 

I only have the TurboXS catback. I have a different test pipe and downpipe. I clear the tie bars which are actually replaced by Cusco's lower arms. I'm wondering if it's because the turbo xs sits slightly lower than my previous catback and this is therefore leaning the entire turboback lower.

 

Heatshield, smack it a few times with a mallet and a screwdriver, mine did it too, and now it doesn't... At least, I would bet a good deal of money that it's the heatshield

 

Thanks for the response but I have a Helix downpipe and a UR test pipe.
There are no heat shields on either.
