Willing to do a few pulls against other systems in the Pasadena, CA. area

After trying the side delete and oem muffler setup, I hated it. The sound was waaaaaay too quiet after getting used to just a center delete, except for the boomy drone at the ~3k range. So I decided to just try no mufflers for a bit. Turned out to be the perfect setup for me. At this point, the valves were useless for the setup, but I already owned them and it didn't make sense to spend more money to get some without valves. I've since sold my 997 that had this setup and bought another 997. I've installed the Sharkwerks race on my current car, but I'm going to try the Dundon/JCR center delete next. Looking for power and potentially high pitched sound due to the titanium center delete. I guess we'll see how it goes. My Sharkwerks pipes will likely be for sale soon.
