The Xtreme is noticeably louder pretty much all the time. It's magnified by headers immensely too.LOVE the photos.
Question: You've had the Xtreme and Sport cat-back....was the Xtreme noticeably louder all the time, or just louder at WOT?
You have to drill out the plastic rivets with a forstner bit and only the edge so that it breaks the rivet but doesn't drill into it because you reattach it with screws.How did you remove the door inserts ?

Thanks Bryn!! The driveshaft was one of those things I knew I needed for boost eventually. I had a buddy who was getting a GT350 and barely had any miles on this DSS CF piece so I went ahead and picked it up from him when I had the chance. I didn't expect any change in the car. I know sometimes people act like, oh man I put on this or that and it's made a huge difference when you know damn well you can't feel shitAwesome build thread Jake! I'm a little late to the party but it's been fun going through and seeing everything you've done to Project Copperhead. Love the copper. Not at first but didn't take long for it to grow on me and the originality is badass! Pardon me if I missed it but how do you like the new driveshaft?? Any pros or cons? Thanks brother :cheers:

So when I drove the car after the install I texted my buddy and was like, dude am I crazy or does the DS make a noticeable difference. The car seems to have a snappier throttle now due to cutting the weight in half from the stock shaft and I was hooking better due to the elasticity of the carbon fiber and less drive line shock. He just laughed and was like no dude, you're not crazy it makes a bigger difference than people realize even on the NA setup. So I've been really happy with the CF unit and am glad I was able to get that vs the aluminum one.
I've heard a lot of mixed reviews about the JMS, enough to make me not even consider it for what that's worth.Awesome that's pretty much what I expected to hear from you about it. If I had planned my finances better before purchasing mine it would be on the list...well it still is, just taken a very back burner to a bunch of other things but snappier throttle response is never a bad thing right? ;) Thanks Jake! I've also been considering the JMS pedal max and hoping for a similar effect but I'm sure the ds makes a much bigger difference
