Is there a company that makes a header back exhaust system (or headers included)? More importantly, is there a way to get rid of the CEL without voiding the powertrain warranty?
Im trying to find someone who will custom fab a performance exhaust for a 97 STS with the 4.6 N*? Would u be able too or know someone who could or is there a company that makes a header back system for it? I would apreciate any help! Thanks!!!!
You can always tune out the CEL. As for voiding the warranty, that's up to each dealer/rep. Your warranty isn't voided automatically(drivetrain). I ran full B&B exhaust on my '04 and had no problems with my dealer. My '09 has Kooks headers(w/cats) and stock axleback exhuast with a tune. No problems with my dealer. Now, if the exhaust caused any problems or the cats failed and caused engine problems, I'm expecting it to be on my dime. But my dealer wouldn't refuse to address an engine or driveline problem because it has mods...
I would love to know more about the B&B headers! Would it be too loud to run headers with a midpipe that has an aftermarket hi-flow cat, and the corsa sport cat-back? I want to be pretty aggressive with my exhaust note, but don't want it to sound raspy or cheap. Has anyone installed headers to the stock midpipe with an aftermarket cat-back?
We do make a full exhaust for the CTS-V sedan and wagon. I haven't gotten a coupe into the fab shop yet to see what we need to change. Volunteers?

Kooks produces a full system that will mate with your OEM exhaust or Corsa exhaust. I've added supplemental mufflers to my Kooks/Corsa setup to eliminate the loud sound of this combo. No problems with CEL codes when properly tuned.
