I currently have the exhaust valve un-plug mod (golf tee). I was thinking about doing a muffler delete. If I do the muffler delete, do you guys think I should plug the valve back in? If it's left unplugged, will it be even louder?

Does anyone currently have both the golf tee mod with a muffler delete and how does it sound? I don't want the car to be super loud and drone-y but I do want my car to sound a bit more "exotic".

muffler delete means you remove the mufflers

golf-tee mod requires that you have mufflers (IE the flap on the driver's side muffler)

^ this

the valve flap is controlled by a unit on the side of the muffler (driver's side)

Usually when people do the muffler delete they'd remove the valve too. So it's either this or that, can't have both

it's possible you could keep the stock tips w/ muffler delete, might make it a little more livable... I must be old though, golf tee on e92 is louder than I'd like, too loud on freeway... dead stock too quiet though.

For this to work you would need a crossover pipe somewhere in the exhaust.

Thanks for your response. I didn't know that, but it makes sense


So I was reading on back pressure if I do a muffler delete and how it'll affect torque at low end RPMs.

Would a resonator delete be better for n54?

Are you on stock exhaust? If so, the cats would provide more than enough back pressure and besides the turbos would appreciate the drop in back pressure (if any, from removing the mufflers). And removing the resonators would induce rasp IIRC.

Yes, complete stock exhaust. Thinking about picking up the OTF tune though. Not sure if that makes a difference.

I plan to keep the cats all in. Removing both cats is illegal in cali from my understanding as it won't pass emissions.

Just want a louder exhaust without having to drop $1k just for sound....
