Have my exhaust made today, when I first saw the silencer, I was very concerned as it was less than half the size of the original, thought to myself I've just wasted £300, its going to be too loud...

I assummed it was a straight thro., then Rick show me his design which was exactly identical to my sketch


My main concern with the sportpipe is its bassnote and rumbling sound may transmit into the interior and ended up boomy and intrusive and ultimately tiring if you travelling over long distances, I took that chance and glad to report that there was no boominess in the interior during the 1 1/2hr drive back.
Soundwise....At idling, its quite, very slight rumble(bearly detectable), but as soon as gas is applied, the sound it emits can only be described as music to the ears(cliche I know), it just woofles with a nice clean bass, pops and bangs were more obvious and slightly louder, under hard acceleration, the bass note seem to have disappeared and was replaced with burbling/flatulent sound

(the flatulent sound was less obvious at low speed than the std sidepipe).
There were no discernible differece at motorway speeds on part throttle.
I'm well please with the result considering this was JP first attempt, its louder overall, but for all the right reasons

Price? £150each

Cereal, I asked Rick about your header, he could only give me a rough estimate £5-£600 each side
