hello everyone

i have been searching for an exhaust and have come across the japspeed exhaust range and have no idea on quality or performance of their parts. i have seen their cars at some of the jap meets in the uk and was just wondering if anyone else has there dual exhaust system and if it actually gives any bhp gains and also how loud it is.

its very cheap compared to all over systems on the market so am intrested to hear what others have to say

You won't be getting much gains from any exhaust unless you're boosted and/or tuned

Paired with a matching sized test-pipe and a tune, you'll see great gains.

i think the system is only 56mm internal diameter so im guessing a 60mm external like most others on the market. they also sell a test pipe soi may buy both from them. can the standard 08 ecu be retuned?
