Can you go into detail for a newb like me.
why did you choose magna flows?
I'd like to know too.
I'm literally at my auto shop getting my Joe Z exhaust and intake installed (they just finished the exhaust)
while watching this video.... I can hardly wait till my PPE headers arrive next week to have them installed as well. I LOVE your video of the ISF hauling a$$ through the French countryside with it's insanely awesome sound with the same mods I'm getting as well. (except will have magna flow cats instead of RT's) SWEET!!!!!!!!

^^^The RT cats are for "street" use only and will melt/fail with headers installed. The exhaust temps from the improved flow of the headers melt/fail the cats. There is a post on here where someone tracked their car with Sikky headers and JoeZ exhaust, and the installed RT cats failed.

But unfortunately, it seems some have failed in basic street use as well..

Intermittent Power Loss & Exhaust Note Change
For the record PTS/JoeZ have never recommended the installation of any aftermarket CATs onto our X-Pipe...
However owners decide to modify, have been their own choices..
Also, we can not warranty our system if something fails in conjuction with "other modifications" made to our exhaust components.
