Found a nice deal for some greddy problem is they're coming off of a 99 GS3 while I have a 2k GS4. Will they be interchangable?

Ebay Greddy...

Same exhaust, should be no problem.

it will fit no problem

just to confirm once more before I get it. So even though the GS3 and the GS4 have different engines, the catback going to the rear have the exact same bends? Cool

Yah...it'll fit.

If this is the Greddy exhaust on Ebay...then the only issue is clearance (scaping the cans).

yah that's the one I'm looking @ he's local tome so there's no shipping so I'll save a bundle. I'll be installing an explosion kit and dropping it about 1.6-2" depending on what springs are available. U still think I'll have a problem/

should be no problem.....just dont drive in SF....those dang hills gonna scrape them cans.

if you are in SF area, you shouldn't drive a lowered car at all let's just say i had a very FUN time driving in that area in my gs4 the other weekend

I never really have problems with my previous ride, 4 door acura legend with andy autosport body kit 2.5" drop with ground control this was a few years ago when I used to hit the club up in Frizko driving home all messed up @ times @ 6am. I actually cracked my kits more time driving here in SJ than I was in SF. The dumbest time was when I was parking @ the mall and did not see the little brick stopper.

haha, that's a bummer. that's why i always back into space whenever possible
