I have a 2005 AM DB9 with 6 liter V12. I just had theX-pipes installed and wow what a difference in performance. The unit is beautifully made and TIG welded. My shop had it installed in 90 minutes. Fit perfectly. Kept the stock muffler. At idle and low rpms sound level is about the same though a bit lower and throaty. Low end power is very noticably improved. Running through first 4 of 6 gears is fantastic. I am 105 mph in 4th and pulling strong. I have not dyno'd but sure there is extra 20 + HP. I wanted more power without more noise and that is what I got. No regrets.
Many thanks for your guidance through my whole X-Pipe process and the tour of the excellent FabSpeed facility. The DB9 sounds far better than I could have ever expected. Not obnoxious in any way but wonderfully toned and refined. The car seems to have been freed by the restriction of the back Cats, I cannot wait to see the video footage you guys took when uploaded to your site. For those potential customers reading this, I had a Quicksilver exhaust on my DB7 when living in the UK. This X-Pipe delivers well beyond that system only with the rear Cats replaced. A fantastic professional job all round from this specialist company.
I installed it this morning and all I can say is WOW! It sounds absolutely amazing and the throttle response is very noticeably better. I would describe the sound as more "exotic". A higher pitch, very pure and crisp tone. I couldn't have asked for more. I'm going to try to make a video for a sound clip when I have some time.
The installation was a breeze. Came with new hardware and everything was pretty self explanatory.
