i dont have any issues with ar at all, im my opinion they are one of the best.
i have expericnced and read on here alot of complaints about the upper o2 sensor placement on the riss's pipes, they are very very close to hitting in most cases, and in the bad cases they actually rattle or hit each other |

+1 I prefer the gradual taper of RR compared to the "I am 3 inches I am 3 inches OH SHIT this hole is only 2.5 inches" of the AR. Not very familiar with the UR pipes, but honestly I haven't seen any of the 3 have bad dyno results.

it hardly matters about the taper down to 2.5, thats the size of most exhaust systems anyway, it seems smoother for the dps to taper to 2.5 then to have a 3inch pipe with a flange that ends at 2.5 to bolt to the exhaust, i would think that would cause more turbulant exhaust flow, again, just a guess

PM me and I can hook you up with some ar design pipes
IMO they are by far the best fit, and highest quality pipes which are made in the USA. I have sold over 50 sets in the last few months and not a single complaint about fitment and quality. I have actually had a few shops comment on how great the fitment is. Mike |
