Thread: Any short, quiet(ish) mufflers for '97-'03 GTP?

Thanks. That helps a lot.

Judging volume by online videos is difficult because of most consumer devices (including phones) using automatic gain compensation (turning down the recording volume when the actual sound gets louder) but the fact that you can still hear ambient road noise and belt whine over your exhaust is a pretty good indicator of relative quietness.

When you're watching an exhaust video, and you can hear belt whine at idle but it disappears when they rev, then fades back in as the engine settles back down to idle, it means the "rev" was louder in real life than it sounds in the video.

"Quiet as stock" is also a relative term, but your video doesn't seem to be much louder than my GP was when I got it. I still don't think 3800's sound good (even if I like the engine overall,) but for a "quiet performance muffler," I'd call that a win.

You should probably start looking through the exhaust catalogs online like I did to find resonators. I ended up with a decent list, but I was looking for long mufflers. Off the top, Magnaflow and Cherry Bomb/AP exhaust had some shorter cans. Magnaflow were available in stainless, iirc. Vibrant makes mufflers and resonators. The resonators are short. Put two on there, lol
