Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
20 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Installed the Stebro Sport exhaust with secondary cat bypass pipes over the weekend. All I can say is I LOVE the sound, breath taking! Install was quite easy, all the mounting brakets and pipes lined up perfectly, even with my cheap, knock-off, ebay headers. Very impressive. :dance:
I'll post some pics, sound clip might take some time as I have never done one before. I have a camcorder but doubt that will translate the true sound very well. Any suggestions on making a good clip?
I've read and heard about other owners comment on resonance between 2-3k rpm. If it's there I haven't noticed it as such, yes the exhaust is much more aggresive and louder than stock, above 4k it it's really wicked. There is also a burble and popping noises when decelerating or downshifting (which I like, sounds like my old C5 'vette with a Manaflow exhaust). I can say it does not sound like the GHL mufflers that I have heard and personally didn't like, it (GHL)sounded nore raspy at 2-3k than throaty like the Stebro.

blue2000s Wow, is that system $2250?
No, I have the headers you can get off of ebay for around $100.00 and Stebro accecpted my offer of $800.00 for the Sport exhaust w/ the bypass pipes.
If you have the headers off of ebay, then I assume they don't have catalytic converters built in them (like the fabspeed ones). I think that means that you don't have any catalytic converters at all - correct? Are you getting a Check Engline Light?

This is correct, I am not currently running any cats. I had my ECU reprogrammed to eliminate the use of the rear O2 sensors, thus no CEL.
