I’m still running stock tune with OEM cars but have been contemplating/timing an exhaust and tune for months now. My car is still under warranty though for another year so have been conservative with any adds. My previous 996TTs came alive with exhaust/tune and sounded much better.

My car came with the SharkWerks cat back and sounds decent but still quite docile in my opinion. Wondering how the cat bypass pipes would help. These are the best value I’ve seen ($500) but are made for the 991 Turbo which I’ve heard are same size as 997.2.

Question on is how much sound will these add and will they fit?
