ZZP Longtube Headers
I have an lsj that's catless with stock catback and it isn't raspy. Maybe a little when it's cold, but minimal at most.

Any idea if this for sure bolts up to the GMPP catback? I would think so cuz my buddy used to have their midlength header/dp combo and it bolted up to his GMPP catback, but just wondering if anyone knows something i dont
That's not a long tube header, this is a long tube ecotec header!

A properly designed long tube should make be able to make 10-20whp on an all-motor set-up, then again that's one that is properly designed with tuned runner lengths, stepped primaries and a true 4-1 merge collector.
