Hello Everyone. what is the best exhaust for most power for 997.1 tt?
I seen Vivid testpipes with resonators which are streight 1 feet pipes to the tails. this as far as I understand will gain most performance, but does anyone drives them on the streets? is it TOO loud? or it is ok?

 

I have a catless Cargraphic Race muffler and I doubt I could feel any difference changing it to a 200-400 cell cat system or straight pipes - IMO they all produce about 20-30 Hp.

 

We have a full 3" version of our 997.1TT X-cellerator cross-flow exhaust which features a modular design. The modular design allows you to use our 100 cell cats or cat bypass pipes and interchange them as you desire. The 3" has piping allows tremendous flow and our internal cross-flow design provides a truly fantastic sound. You would be amazed how good this system sounds! It is also available in a 2.5" quiet version.

We also offer a "super sport" version that has no mufflers...just our X-Flow design. If you want it really loud, you would love this version. Shown here with OEM tips, but can also be used with the true 3" dual tips shown above. Again, it's modualr and can be used with or without cats. The X-pipe piece can also be purchased separately and switched with an internal cross-flow muffler, too. - if you would like additional options...

 

That 2.5 and 3.0 exhaust you show on he sound bite is sure a great sounding exhaust. is that a cold start clip or one on a warm engine??

 

Hi John,

Thanks for the kind words. That is not a cold start - it's after a brief stop, but things were definetely warmed up. This exhaust sounds absolutely incredible - the customers that have purchased it, love it.

I would put the sound of this system up against anything else on the market, regardless of price with confidence it would emerge a strong favorite.

Additionally, it is manufactured in the USA with top quality materials, so the quality is also extremely high. Options include mirror polishing and full ceramic coating.

Regards,

John

Tube Race Exhaust is by far the best sounding system IMO. Love it with 7k miles on my car

 

FVD sound version all the way!

Check my link below.

 

I have to agree. The Europipe exhaust for the 997.1 is a stellar system with an unbeatable sound.
