Great looking car and I like the concept!

My Spec Boxster currently weighs around 2,461 lbs with no fuel (close to 500 lbs lighter than a stock 986).

Entire car build is documented here (thanks for the shoutout Chuck!): http://986forum.com/forums/boxster-racing-forum/46070-spec-boxster-build.html

Also, the muffler you installed will give you a few extra horsepower at the high rpm (dyno results are in the link above) and removing the cat's and installing test pipes will definitely increase the SOUND LEVEL. I wear earplugs.

DMS Lifts, it's a regional company based out of MO. Lots of local guys have them and are very happy.

Yes, Guards Red. It looks great in person after a detail, the pictures are a little washed out.

I went through a similar process with my 2.5L Boxster and got the street car weight down to about 2800 wet. That made a noticeable difference in performance of the car. Light weight seats and an AGM/LI Iron battery will probably shave another 100lbs.
Thanks, both are on my to-do list. I would love a nice set of more aggressive seats like a Recaro SRD.

Great info there, thanks!

I had that same muffler with cat bypass pipes on my 04 S. It was too much for me. As in it gave me a headache after 10 minutes. I took the muffler off the same day I put it on and put the stock one back on. This is coming from someone in their early 20s! The stock muffler with bypass pipes is a little quieter than what I would ideally want but I think it is a good compromise. Not to mention I think the stock tips look and fit a lot nicer.

Lots of people on here have the combo and like it, however. It just depends on what your preferences and expectations are. You've been warned

front cats

Where do the Oxygen sensors go after "cats" are removed?

I have the same concern, but there's only one way to find out. At the moment it's marginally louder than the stock muffler. Once it sounds like my 911 with SSIs and a Dansk sport, then I'll be happy.
