Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I understand that the R has a slightly larger diameter system but I suspect a lot of the crackly quality and blipping on downshifts is more ECU based.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

OK So I've sent my Cayman R off and settling back into life with the Unicorn S. Its awesome. Sublime. BUT theres one single aspect that the Cayman R nailed better. The exhaust. I have the PSE and the Cayman R I owned also had PSE. I understand that the R has a slightly larger diameter system but I suspect a lot of the crackly quality and blipping on downshifts is more ECU based. So what options are there? The PSE sounds fantastic I dont really want more volume but the blipping/slight popping of the Cayman R Exhaust I do miss. I'm reluctant to let anyone near my ECU unless they really know what they are doing but equally wouldnt want to fork out for a replacement exhaust if the ECU is doing most of the work to make it sound better. I wonder if that green R is still on the market? Is there anyone in the UK or in Norther Europe (Carnewal?) that could do a couple of ECU tweaks?

POST 2Original post

Do you mean auto blipping of the throttle on downshifts?

POST 3 / ORIGINAL POSTEROriginal post

Yes the R has more of a pronounced bark on downshifts

POST 4Original post

There was a CR PSE exhaust on eBay a week or two ago?

POST 5 / ORIGINAL POSTEROriginal post

Must have missed that. The bogey green one that had a fabspeed and a spare oem looks to have sold. Maybe it was that one on ebay? The difference between the S and R is really subtle so im keen not to bugger about with it too much and spoil the sound.
