I was using Fabspeed x-pipes with 100 cell cats, that Dansk one looks like a cross over type in which case it will not allow mixing as per the description.
Not sure about a power increase but it is a bit louder. No problems with emissions testing. Ditched the cats and it's a lot louder.
Some say the crossover design is better for cylinder scavenging and improved midrange torque, others say the x-pipe is better.

I’ve always found Dansk cats and mufflers nasty. Have you tried Cargraphic or what Endoman said Fabspeed? I have Cargraphic cats and they sound lovely with Gert’s RSR’s.

Where can one get the Cargraphic cats?
Ive had de cat pipes in the past, sounded lovely, but failed on emissions and the car was a bit fumey (high track miles)
My exhaust boxes are very good as they came off a very low mileage car, I put the old standard cat on to pass the MOT, but the car is so quiet, so fancied a halfway house ....100/200 cell cat...

I looked at Cargraphic exhausts a few years ago and found Parr was my local supplier.

I have been running decat pipes for the last few years - every year I Garage for winter and budget for a 100 cell CAT and add the to the list......as soon as I start the car it goes straight to the bottom of the list.

I do realise I’m being anti social etc. so to keep the balance we bought a full EV runaround......my conscience is clear.

Does it pass the MOT?

PostPosted: Sat Jan 06, 2018 8:52 am    Post subject: Reply with quote

I spent a lot of time looking for 100 cell cats for my 4S and in my opinion the Cargraphics were the best 100 cell system on the market that I could find. I bought and fitted mine in 2015, they were the most expensive option at the time but definitely worth the extra money.

I discovered SCART too late, but would've considered them if budget allowed. They sound so good... Very Happy

That does sound great but the text seems to indicate that car is fitted with 200 cell cats which aren't listed for sale on their website, only 100 or 400 so I don't know if it would be possible to replicate that sound with their current offering.

This area of things is all new to me so please forgive a stupid question. What does the cell rating signify? I'm guessing that the lower the number the higher the noise level and emissions will be. So does the decision just come down to personal preference of how loud one wants their car to be or is there more to it than that? Is there one manufacturer that's generally regarded as "the best" for 993 exhaust parts? Question

Link doesn't work, but think I've found what you mean.
So there is a few options appearing.
The Cargraphic ones are cheaper than the Scart... and look the business, wonder what they sound like... Thumb

I used to have Cargraphic x-pipes but they needed a bit of adjustment to fit. The clamping system and springs are a bit of a pain.
Fabspeed are much nicer, easier to fit good clamping system, excellent welds and versatile, easy to swap cat/decat.
I know the name sounds a bit dated but it refers to Joe Fabiani not the Beatles.
I liked them so much I bought the silencers as well. (not the Supercups which are ear piercing)
The Scart system sounds way too loud.

Did you have to buy direct from the US Endoman, or are there UK suppliers?

Design 911 stock them or used to. I got the x-pipe cats from them but the decat pipes and mufflers from the States with a Black Friday discount.

Thanks. D911 are listing the cats as a special order item but the Bischoff type are twice the price for some reason. I bet I'll need the Bischoff type. Rolling Eyes

They don't seem to have the Maxflo mufflers which is a shame because I do like the look of Fabspeed. Are the Maxflo the ones you have Endoman?

Does anyone have a link to an idiots' guide to 100 / 200 cell cats so that I can get an understanding of the differences/benefits for each please?
