Im thinking about buying the next upgrade for my 97 gst and I was thinking of upgrading the downpipe to a racepipe eliminting the cat. See i live in west virginia and they dont run emission test! So would this be a good idea considering the upgrades i already have (bottom). I found a race pipe on stillen.com that seem to be a good deal....all of the other racepipes i have seen have been apexi that say "must be used with apexi exhaust". If you guys know another place that i can get one for cheap give me it would be apprecieated. If you guys were me what would you go with next? try to be reasonable lol

Greddy 3" Catback Exhaust
Injen Intake
Hks SSQV bov w/recirualtion
Dejone upper intercooler pipe
Denso iridium plugs
MSD superconducter wires

 

unless you find a greddy specific downpipe (which io dont think exists) you will need to do sopme welding. Buy a straitpipe and some flanges and have someone weld them
