Any updates? How do you like the sound with the bypass pipes, in conjunction with the stebro race exhaust?
I've had the stebro race setup for awhile now and have loved it... Just tonight, I decided to try it out with the bypass pipes... I'm not sure how I feel about it yet...
Sitting and revving, it makes a great sound.... I've only driven a few miles so far with the new setup.. It is LOUD... Not sure how much I like the sound at lower RPMs right now, and driving normally around town... When I romp on it aggressively, the sound is awesome... Still debating if I like it overall or not....

exhaust baffle for race exhaust
I, like so many others here built my own exhaust system. I basically copied a stebro race setup, but i used aluminized 2" steel.
The sound is identical (to my ears) to all the stebro clips that I've heard. The sound is awesome. Of course I got the "drone", but I also got a faster throttle response (which I love). I haven't had a chance to dyno it yet because the only local shop with a dyno has computer software/hardware problems. Hopefully they will be up and running soon.
My understanding of the drone problem is pipe length (engine vibration causing the pipes to resonate at a particular frequency based on pipe length) and lack of acoustic baffling to combat the first problem.
Would a tip insert style baffle (like the harley guys use) do anything to help with the problem, or would it only lower the decibel level? It might just move the drone to a different rpm range.
I'm just thinking out loud I guess. I've only got $200 bucks in this project, but I would really like to keep it installed. any ideas?

03-04 mufflers sound a bit deeper, and also have provisions for mounting different tips.
As to getting rid of the drone on your exhaust, I don't think you're going to get a drone-free exhaust by utilizing that type of design. For what it's worth, I have the dual muffler FabSpeed setup, and it sounds amazing and is drone free.

i'm curious if the "maxspeed" system out there is essentially a knock off of the fabspeed system and is truly the same thing?
the sound clip video they have on their website / youtube sounds cool.
i also heard a sound clip in youtube of a base 2.7 wth a RUF exhaust and it wsa AMAZING sounding.. but I haven't seen anyone selling a RUF exhaust for our cars.

Maxspeed Exhaust
I've driven my 2.7 with the complete Maxspeed system now for 600 + miles. Honestly, I haven't thought about drone at all because it just isn't an issue. If there is some drone, it definitely isn't offensive. The description of the system from Maxpseed is accurate.
BTW, no CEL issues at all (knocking on wood)!
