996 Turbo - Sports Exhaust

[stubbsy996]

I've been toying with the idea of fitting a sports exhaust for some time. I've been advised by someone who's apparently in the know that if I fit a Milltek 100 or 200 CEL cat that I'll need a remap, otherwise the car will "over fuel" (whatever that means)!
Is it correct that I'll need a remap?
Has anyone fitted a sports exhaust on a 996 Turbo without having had a remap and if so were did you experience issues?
Should add that I'm not really interested in increasing bhp, car's plenty quick enough without remapping. Just want a better exhaust note having come from C2 with PSE

From my previous car ownership I know turbo cars in general are more sensitive to changes in back pressure. Also, you may throw an engine check light if the lambda sensor is after the CAT.

You probably need a remap, or advice from a Porsche expert

not true.

I have an aftermarket sports exhaust (cargraphic which I think are 200CEL cats) and have NOT had the car remapped, no CEL's and its been through about 3 MOT's since I've fitted it with no issues either.

You may still damage the engine though. Totally different car, but on my old Scooby putting sports cat in without a remap would cause it to boost spike.

I've had zero issues since fitting a Ruf 200 cell system to mine Stubbsy. Ruf estimate a increase of 12-15bhp, probably due to the lower cell rating and their internal mods, so I'm guessing other systems might offer similar gains, which is always a bonus on top of a better sound

I would have thought buying a lower cell rated exhaust would come with an advisory for a re-map if it were the case any damage could be caused.

I have a eurotek on mine, no isssues at all, includes 3500 mile european tour, trackdays etc etc.

No remap and sound is far better than the miltek imho

You do not need to remap the car to fit an exhaust unless you fit a catless exhaust but even then you just turn off the sensors!


If you want a nice sound then I would steer away from milltek and go for something like an FVD system or a Europipe stage 2 loud!

Thanks everyone for your input.
Milltek was recommended as best value for money with nice sound - can get one fitted for approx £2,500. There was a previous thread on best exhaust for Turbo and everyone that had one had only good things to say.
FVD and Europipe v nice but expensive!
