Strange exhaust tip color after trackday

RINTAXI · 05-25-2015, 05:31 PM

Check this out... first time having this issue since multiple trackdays. Can someone tell me what's wrong? I could wipe off these white powdery stuff easily btw.

This is an IPE exhaust with Macht Schnell catless x pipe

I assume there is something wrong with my exhaust, not my engine, since there is only one tip got these white color residual... But not sure...

It's from the heat of the exhaust, nothing more. That means your car likes you!

It will polish right off, but it will come back occasionally.

Thanks for the info, sir! I did drive the car very hard on the track and I loved it.

What size spacer are you using in front? Are you 275 up front?

How is the 8mm? Is there enough hub to fit the wheel on still?

I'm thinking of just moving up to 12 or 12.5 whichever fits our car since I added more camber up front.

Thanks man.

On my old Arc 8's, 18x10 ET25, I ran the 12mm spacer without issue.

I am running -2.0 camber up front but I am still rubbing a bit at full lock of steer... So I don't think go with 12mm is a good idea.

Does the X pipe combine the exhaust gases from both banks of the engine?

Looks like yes it does

Were you running race gas? Or leaded perhaps?
