Hi

I'm toying with the idea of a Janspeed exhaust for my 968 or at least the back box. But the pic on the ProMax website makes it look a bit bling. Does any one have one of these on their car and would they mind posting a few pics?

Many thanks

James
 
i got one too. i was a bit cross because the ESS website shows a pic of an oval exhaust and the one that arrived had a big bling round pipe. eventually however i decided life was too short to replace it again, and it sure beats the hell out of a stock exhaust for sound - half the price or less too. can be a bit boomy now and again but overall i thought it a success.

I made sure mine was the oval tail pipe... Yes i found it a bit boomy at times too....I just put it down to the fact it was on a cabrio which had less sound deadening, ie no solid roof....[;)][:D]
 
Did you guys have the single pipe Janspeed one or the 2 pipe Cargraphic copy one? I think the number of pipes is what makes it boomy. My S2 is very boomy at motorway speeds because it has no Cat just a straight SS pipe all the way to the back section. Large diameter pipes will promote low frequency waves i.e. noise (think like a pipe organ), whereas 2 smaller pipes will shift the spectrum up to a higher pitch. The Cat will dampen out the strong pulses from the engine, hence why I wouldn't run without a Cat I think it may sound a bit boy racer, my S2 does sometimes for example and can be a bit rude at times but sounds great at 4K rpm. My 968 has what appears to be a Cargraphic back box and that IMHO sounds really nice.

My S2 had the twin outlet janspeed with a single main pipe , without cat..I didnt find it boomy, in fact it was just perfect..
Ive had the Janspeed single pipe system, with porsche cat,, that was on my 968 cabrio it was boomy..
I now have a cargraphic twin main pipe system with Porsche cat, on my 968CS i find it great...No booming...

Thanks for all the comments chaps.

Dave - it does look good on your car I have to say. Here's a pic from the ProMax website. That tailpipe looks oval to me.

Cheers

Sounded really good on your Oulton video.

I dont remember mine having the perforations in the tailpipe..
Maybee thats an evolution of the kit to help reduce the booming....
