Hey Guys, I just posted this on Rennlist but wanted to share it here as well.

I just had an amazing experience with Speedtech so I decided to share it with all of you.
I bought my 997TT last September and I immediately wanted to get a better sounding exhaust, the stock exhaust was terrible in my opinion.
After hours of research I had decided to get a Tubi exhaust but before I purchased it I got the chance to drive a 997.2TT with one and decided it was too quiet for my taste so I was once again doing research online.
I came across a review on 6speed that made me decide to give Speedtech a shot and I ordered their 3'' cat-less X-pipe exhaust system. The entire ordering process was seamless and my new exhaust arrived about 10 days after I ordered it. I installed the new exhaust myself which fit perfectly and fired her up, for the first week or so I absolutely loved it! It was extremely loud, throaty and it made wonderful exotic noises all throughout the RPM range. However after about a week I decided It was too loud for city driving and It droned too much between 2000 and 3000 RPM. I gave Chad at Speedtech a call and told him this and he offered to send me a different version of the exhaust, the 2.5'' X pipe at no cost as long as I sent him the 3'' back. He said he thought this was the perfect balance of loud and exotic without being too over the top.
About a week later the new exhaust arrived and I swapped them. I immediately went for a drive and wow! It is the best sounding Turbo I've heard! It is loud without being to loud (IMHO), it sounds like an exotic car now and it makes all sorts of noises that I absolutely love. I've had it on my car now for about 3 months and I love it more every time I start the engine!
I would definitely recommend SpeedTech to any Porsche owner out there!

 

is their any drone with the 2.5 system?

 

 

Love my Speedtech!

 

Not really for the majority of 997TT's on the road. There is virtually no difference between our 2.5" and 3" exhausts on a dyno, up to the 700 HP level. IMO, it is more of a sound level preference choice.
