Oh yes...sorry I missed that you already had the Eissenman Race exhaust, so no need to get the Dinan exhaust. Don't forget labor costs for the inter-coolers, which would probably run around $500.

I just cant justify spending 3k to go to stage 4. Diminishing returns start to kick in when spending that kind of money for maybe a 20 hp bump.
