Best Exhaust/Downpipe for STi RA
#1
Anyone have an opinion on the best backbox/downpipe combination for an STi/STi RA? According to the Dyno page, Scooby Sport backboxes and PE downpipes seem like a popular combination.
Thanks,
Max

BPM is one of the nicest sounding
I dont mean to upset cpofWales but the Mongoose has a fairly restrictive downpipe - its pretty much the same design as the OEM one not having a twin dump outlet, but rather a blanking plate = restrictive, its saving grace is that it is decatted.
You will get more power out of Scoobysport, HKS or BPM (HKS is expensive, and BPM is downright extortionate)
