-exhaust (catless for more power)
Ive seen some people using meth kits on the forum but never had the chance to see one in person or dyno one.
I'm not to fond of meth kits but then again drew always saw positive results and I would on one, run and on another it would drop in power but I think that's due to nozzle location .
