AFE just released their exhaust for the RHO, im not sure if that fits the other HO trims like my limited yet I was gonna call monday and ask. Borla is testing theirs as is AWE so im guessing those will be out in the next month or two if you can wait like me... also Corsa is releasing theirs in next couple weeks and from what I heard so far sounds pretty good actually... I think we are all smart enough to know it won't sound like the V8s but that doesn't mean it won't still sound "good"... I dont get why so many people are so negative on here 6 cylinders can sound pretty good supras... GTRs... new M3 I know different engines but still sound good.. so sick of these cranky old guys mentality its not the HEMI or its not a v8.. sound like my 3 year old whining lol. tell me they dont like change without telling me you dont like change lol. I digress, anyways some new I think exciting kits coming out soon!
