ISR Performance?
Who knows what about them?
Formerly ISIS performance, it seems like they're mostly popular among the S-chassis crowd. I'm hearing things about them possibly being a re-brand/revamp of Enjuku Racing but I have no idea how much truth is behind that. Either way their pricing is on par with CNT/Megan so I'm curious if they suffer the same quality woes or if anyone has any experience with them. Their resonated test pipes can be found for $160.
Who has or knows someone that's had experience with the brand?
