i've searched for a whole day on this and i cant find good info on the RS-R. If i go with this setup
-Hallman MBC
-Injen Hardpipe ic pipe kit
-hks bov
-hks 264/373
-helix DNA intake
-apexi Safc II
-Fidanza Cam Gears
-APR head studs
-downpipe ( helix or RSR)
-HFC (helix)

If you get the RSR downpipe, you wont need the HFC b/c it deletes the cat right?
Around how much HP should this get? Anyone have experience with the weapon R engine dampener?

 

yeah the helix dp deletes the cat completely its not SS but some guy on the forum i believe is selling one.... used save some money

 

You mean the RSR deletes the cat rather than the Helix. I personally would go with the RSR.

 

bump ty for ur responses so far.. so we would be lookin at more power with RSR?

 

since the rsr deletes the cat, it would make more power. but you can use the helix dp and test pipe.
