i searched but it kinda didnt really answer my question. Will the Apexi N1 Duals bolt up to a RB downpipe /w pre-silencer?

 

Yes. You can use RB DP and PreSilencer with any catback exhaust as they replace the cats and are the same length as tthe cats.

 

isn't the Apexi Y-pipe a bottle neck though??

i want to put the N1 duals on my turbo back RB exhaust but i was told my Y-pipe is more free flowing.

truespin88, do you know if i can "bolt on" the canisters to my RB Y??

 

N1's are ****** so nice. There sound is unmatched.
Not sure what they sound like with silencers though.

 

No, the Y-pipes are not the same length, I don't think. Your best bet is to get an RB y-pipe, and a pair of N1s with 2.5 universal inlets, and have an exhaust shop mate them. You can then have them out at an angle like the cat back system is, or straight out like some prefer.

The Apex'i Y-pipe isn't as free-flowing as the RB y-pipe.

 

i already have a full RB system..........i just want the N1 bombs on the end!![and angled of course] :coo:
