Default Best exhaust for 993 TT 450hp engine?

Hi guys, recently bought a 993TT with factory fitted 450hp kit

It came with the standard 450hp exhaust but I feel it's missing his voice...

Any good reccomendation on what's the best aftermarket exhaust I can fit to the car in terms of noise/performance? Not really looking to get more HP, more not to lose any to be honest

Many thanks for your help!!

Take off the mufflers, and put on Fabspeed bypass (less weight & less heat). Or, send your mufflers to FD Motorsports, and have those guys work their magic on stage #3.

I have Fabspeed 200 cell cats with x pipe and muffler bypasses and couldn't be happier.

100 cell cats and the above. Or even better, cat bypass if you don't need them.

Thanks guys, the car will be mostly used on track so need to find a solution that gives some charachter but will allow me to take part to UK trackdays, which are a true PITA when it comes to noise regulation! I guess full straight pipes not really an option for me...

the turbos quiet down a lot of the noise, but its not quiet.

I run 200 cell sport cats and muffler bypasses and am quite pleased.

What's the bd limit at your track? I have catbypass and made muffler bypass elbows. Have had them on for the last 4 years or so. Numerous days at Laguna Seca with a 92 db limit. Never got black flagged (yet) although I know I "stayed out of it" somewhat when passing the sound box. Recently made LPMM's out of my cans just as a precaution. Idle is the loudest with straight exaust. Once turbos spool up it quiets down. If your db limit is above 92, I'd opt for straight without cats or mufflers. You'll love the growl.

These are the muffler bypass elbows I made. If you can't do it, take your cans to a good muffler shop and have the guy make these by using the cans as a reference (inlet/outlets).

Thanks a lot, very useful! Most of tracks are limited at 95db, some even higher so should be fine...
