My head and oil pan were never removed.I basically raced myself, didnt care too much.Imo, changing clearances, decking stuff, cryo/shot peening, rod bolts and whatever other built engine voodoo you choose to do kind of defeats the purpose.But hey, as far as I know I still have the...

Drove it

I have never used our catback with anyone else's downpipe, so I can not.I can however make our downpipe with a 2.5" flange at the o2 housing if you so choose.

I designed, built and tested this product on my 100% stock gsx.First, the cat was removed, jigged and replaced with a test pipe. I then worked backwards off of that to develop the catback with the stock downpipe still in place. Only after the catback was completed did I remove the downpipe to...

I used evo flywheel bolts on mine when I had it back in the day.

different spacers were used.they might be 7.5, should say on the inside of the rim.
