i'm about to get a greddy ti-c for my '99 si. but wat i was wondering is that i have dc 4-2-1 headers and if i just get the exhaust, will it fit directly on? or would i need to get any other piping? thanks for the help

 

If it's a full Cat-Back, it should come with everything you need like the Axle-Back part of the Exhaust, and the Mid-Section which can sometimes come in one or two pieces. But it's the "FULL" Cat-Back, and it's made to fit your car, then you shouldn't have anything to worry about...

 

thanks for the help.
