Cool thanks guys I'm actually thinking of replacing the stocko rear muffler on my 200sx with an XR6T part for cheap (hence the low power goals lol). I'd have to come up with a 2 into 1 y-pipe though, because the stock muffler has a single pipe entry with dual exhaust tips. Cheers

Hey All Was wondering how much power can be made on an XR6T with the standard exhaust system. Also, has anyone measured the maximum backpressure (at the o2 sensor) at a standard or modified power level? Trying to decide whether standard system will be good enough for a ~240 rwkw setup or if it needs upgrading. cheers ps.
