Well, I have a Greddy SP cat back and I'm going stage II this spring. I don't want to replace my exhaust, but if i'm not mistaken the piping is only 2"? Anyone have any suggestions?

I've grown quite fond of the SP sound. Not too ricy, a nice deep tone.

keep the muffler and resonator and just get larger piping to replace the greddy piping. that way, same sound and better air flow.

DarkOne> but we all have that inner ricer that is just dying to come out sometimes...

I thought the gst and gs/rs piping were the same except for the high flow muffler and extra resonator, correct me if I'm wrong

tip is the same between the gst and gs/rs, but the piping is .5" bigger with the gst. well, 10 more mm anyway.

I believe the SP is 2.25 piping. You defiantely want to enlarge that somehow, either get 3" piping from a local muffler shop and have it installed or upgrade your exhuast to the EVO or something. You'll have too much backpressure.




In order:
Mirror Tint|Grillcraft grill|SprilMax|GST Exhaust|Front/Rear strut bars|EBC brakes|Brembo Crossdrill/slotted rotors|AEM CAI|NGK Plugs|Magnecor Wires|Koni

I had the NA greddy piping on my car when i bought it.... was boosting 18 psi on it, whoops... when i reworked the exhaust, it was almost a night and day difference in spool up... I'd just sell it on ebay... I boght a mangaflow straight through race muffler for ~100 bucks, got a new downpipe made for ~180, and catback made for ~150, sold the greddy SP on ebay for over 300... so it worked out real well, my advice is do the same thing , you'll be very pleased.

I have an N1 catback all my pipes size are 2.25 inches from the downpipe to the catback and now I'm boosting 8lbs I feel a lot of back pressure I hate it cause everytime my auto shifts it sound like someone just broke wind like bad........ I'm going to get a loca muffler shop to make me a custom 3 inch piping for my exhaust.
