Will a Carnewal knock your emissions up come MoT time?

My understanding is the Carnewal exhaust modification for the Boxster/Cayman includes removal of the secondary cats. Mine has sailed through 2 MoTs since fitting without any noticeable change in the emissions.

Took Gurt 70 mins to do the car, Needed new clamps and ss bolts as well. Took about 200 miles for the car to bed in, Sounds good, could be a little louder for my liking but it feels to rev better through the rev range. Worth it, Yes. Steve

Steve Sounds like you need full throttle acceleration to the red line chap

It's one of those things. Initially I thought it was too quiet. When you get used to it all-round though, you realise it's actually perfect. It can be barely louder than stock when pootling, then you get the flat six wail when pressing on. It's also fapping loud outside and I'm not sure I'd want to draw much more attention than that... A lot of the loud systems emphasise the drone you get between 2-3000 rpm and can be horrible when pootling. Obv the solution is not to pootle, but it's nice to have the option when you're not in the mood.

Steve, what was the total cost to change including the couple of additional bits, if you don't mind me asking.

all in, my GT Exhaust cost me £420 inc. bolts and clamps

Cheers Rob.

I discovered a much cheaper option to get that meaty roar. I floored it away from a toll booth near Rouen, trying to keep up with a La Ferrari, and popped the 3 exhaust flange bolts on the left side ! How the locals must have enjoyed that as we left Le Mans town centre at 11 pm after the drivers' parade! The drone got a bit boring on Monday's 500 mile journey home though...

yep, i went over at Easter to have it fitted whilst i was in Ghent

I have been told my my supplying dealer that if I go the Carnewal route it will invalidate my warranty. As car is only 8 months old that concerns me. Test drove a 981 with PSE yesterday and was impressed compared to stock but best price fitted £2k.

It's pretty much a given that having your exhaust fettled is going to do the same.

I think it would only invalidate a claim that could be demonstated to have been caused by the modification. At least that's what I've been told by OPCs. They won't reject a claim for a gearbox problem because you swapped the exhaust pipes .

Has anyone actually had a warranty claim rejected due to a Carnewal modification? I'm looking at a car with an OPC warranty remaining, is a £2k PSE the only option if I want to maintain the warranty? Not bothered if it invalidates the warranty on the exhaust, but if the engine goes bang I want it.

I am in the same position with a year to run on my CR. the small print gives Porsche plenty of room to reject claims, but my only experience is with the windscreen where I got confirmation that a non Porsche windscreen, fitted by Autoglass, would not affect the warranty unless there was a related link. So I guess that if a windscreen leak fried some electrics then they would void a claim. Seems reasonable.

Thanks, yes that would be my thoughts, if it is linked to the issue then fair enough. I think the problem with the exhaust could be that if the engine goes bang, they could somehow argue it is linked and deny the warranty claim. I'm looking at a Gen 2 cayman, so whilst that may seem unlikely, it is still a concern.

I had a carnewal exhaust mod on my 987. It's very discrete, so much so that it went in for main dealer services twice and they didn't even spot it. Make of that what you will!
