A friend of mine has a J's racing intake and an rs-r exhaust system for a civic si and he's giving me a hell of a deal on them. I wanted to see if the J's racing would bolt right up? Also, i wanted to know how much modification would be required for the RS-R exhaust system? Any help would be greatly appreciated. Thanks

 

The intake will be fine. The exhaust is going to need some modification. Take it to a muffler shop What model exhaust is it?

 

yea the exhaust would require slight modification, what kind of rs*Rexhaust is it?

 

the exhaust is the GT2 MAG. Let me know what kind of modification will be needed
