What type of exhaust is this on my new 997.1?

Hi,

I recently purchased a 2007 Turbo. The previous owner informed me it had an aftermarket exhaust (I got the stock exhaust as well), but he doesn't know what kind it is as it was on when he bought it. I rolled around under the car tonight trying to find some sort of identifying markings, but no luck. I believe it could be a Milltek from the poking around online that I've done, but that's a pretty big guess.

Any assistance would be appreciated.

Cheers,
Dion

Thanks for the input Sam!

How would a system like this compare to a Kline system? And if I went to a decatted system, would I have any CEL concerns?

After removing the passenger intercooler to address an oil leak, I found this tag on the top of the cat:



And also this stamping on the side of the cat:



Any ideas on if these are 100 cell or 200 cell cats?

Did you ever determine if these are 100 or 200 cel?

Steph at Europipe sent me a Private Message letting me know that if they say HJS Tuning they are 200 cell and if they say HJS Motorsports they are 100 cell - so mine were 200 cell according to the stamping.
