Muffler Bypass db levels?
Does anyone know what the db levels for muffler bypass pipes are? I had an older Cup style system installed and its close to as loud as mbp pipes. Just making sure i can pass sound at TH. TIA!

not sure about cup car exhaust, but fabspeed bypass will pass sound at TH.
i believe stock cup car exhaust will pass as well.
RSR will not.

How much louder is the muffler bypass than the PSE? I have the PSE with one muffler doing a rattle. Has anyone gotten a muffler fixed? Does anyone have a sport exhaust to sell? Thanks Chuck, I guess I should wake up before posting.

what check engine light...been running bypass pipes for 3 years (with mufflers back on for Laguna Seca) with no cel issues...the cel issues I have heard about result from cat bypass not muffler bypass...

Martin, call me i have one modified oem muffler in storage, I can't remember if it's left or right though, I think right.
I also have a set of GHL mufflers if you're interested
Oh, MBPs read 108 db at 15ft
My CG i think is 98, i have the full R system which according to Fabryce (if you get a straight answer) is very similar to the cup system that was on their 996s...

No clips, go to cargraphics website I think there's one.
Yes it crosses over, it's great, gobs of torque! I love the mbp sound, but the loss of torque bothered me.
Funny, guys on harleys couldn't get over my car being louder. I have a harley, and it's no where near as loud as mbps

I checked, i think its their non R system though
Really? I thought with the cross over the sound would be more mechanical? I agree, love the loudness of mbp but didnt want the loss of torque either. GMG's Cup bullet system was exactly what i was looking for. Muffler bypass pipe loud, slightly more refined, but no loss in torque for a lot less than a full system.
