Hi folks,
Ive just got back into a 911 (997.1 C4S) and am thinking about the top gear exhaust. I put a 200 cell speedtech on my 996tt and the increase in response, noise, and feeling of mid range power was very impressive. But it was bloody loud! and actually stopped us using the car for long trips with the kids die to 2k rev drove (it wasn't actually a bad noise, just a loud noise!)
So, ive two questions to ask of the Top Gear 200 cell switchable owners:
- with valves closed, how loud is the Top Gear exhaust vs the stock exhaust sound - cold start, and cruising
- with valves open, how loud is it vs the Gundo hack?
- what performance improvement do you guys 'feel' with the cats? More response? free revving? mid range power?
Have to say that even stock exhaust with the BMC filter and Helmotz delete is sounding awesome! Would be great to get a bit more noise and power though :
Many thanks for any replies,
james
