Looks good !! bet it sounds awesome.

Nah Hellcats not attached to an anodiser !! lol.... if I was my bike would be very black and purple !!..
Poor guy would be plating stuff for my bike forever.

yes I know Gremlin and Clive they've helped me in the past and I've seen his anadising work. Thats a good shout to get them anadised gold! Long way to go with this s4, but not until the winter when I won't ride. Just unbolt and rebolt

Just sent to me from the 2 guys who worked on the exhaust, I cannot emphisis the quality if the work from these 2 brothers. nice blokes as well

Does it matter the a length of pipe from the vertical cylinder is alot shorter?


what's with the standard chain cover ,

standard cover hahahaha actually have the replacement cover in my hand now about to go on cheeky git :-)

don't think it mattes about the vertical pipe been shorter, I'm not getting any running difficulties, its fine on idle which is quite a surprise.

You got to try and get a sound byte up mate, they look stunnin now I want to hear them!!

Can't you do a Top Gear style and at least get a sound/decibel app. It would be good to see the figures.

The problem I found with sound recordings is they adjust there level according to the volume, so it's hard to get the real idea of the true volume.

Not as loud as now, but I think my old Mivv's created a better note than my new setup.

when left on Idle and the mike about a metre from the exhaust I was getting a reading of 99 decibels, I think the legal limit is around the 85 mark! Oops

If I remember my physics lessons correctly (but that wasa bloody long time ago!) every 3dB is a doubling of the noise ;o)

Enjoy
At least no one will say they didn't know you were there, loud pipes saves lives and sound bloody marvelous on bit twins ;o)))))))))))))))))))))

These do the bike justice

They probably look and sound awesome but would be detrimental to the performance IMHO

yes I know, I've always been more interested in the aesthetics than the performance. I will take a look at it over the winter and see what can be done to make amends. I imagine I;ve lost some top end. Good thing is that its not a 916 engine in there its a 996 test engine out of an s4r so it had some extra ooomf anyway.

I was looking at the right hand side and I've noticed they follow a similar line to the old RR exhaust, only on the other side. A word of advice: careful when leaning the bike over as mine used to scrape the headers, lighten up the rear wheel giving way to scary moments. Needless to say I got rid of them.
