Will the muffler delete cause issues for those of us who must pass emission testing?

For L99 owners who did the muffler delete, how significant is the drone?

:confused:
Zero emissions trouble...i have to be emissions friendly. The mufflers are not related to emissions. As long as you keep your resonators in place or go with an resonated x pipe your fully legal. You car needs a muffling device of some kind. Alot of people..me included went with x pipe and no resonators...imo its a little to high pitched so ill get a resonated x pipe in the spring. I found zero drone with muffler delete...zero.

No drone but AFM will drive you crazy. Delete both and be happy!

Is your comment about AFM related to the muffler delete or a separate issue whether the mufflers are there or not?

I don't doubt you, but I gotta ask, why do you think some L99 owners are complaining about drone after deleting the mufflers?

:noidea:

Im not speaking about anybody specific but some of these guys think drone is coming from the afm. And some mistake the sound of a rumbling v8 as drone. Drone effects people different. If you read through this thread there is a few posts that aren't very helpful. Myself I can't stand drone. Muffler delete does not drone imo.

I have the Solo axleback with J-pipe to cancel drone as many others have. All I can say, is that if I had drone, my wife would let me know. There is absolutely zero drone with this j-pipe set-up. I can't speak to just a muff delete with no j-pipe. I had what I would consider a bit of drone BEFORE I did the muff delete. It was at about 110kph while cruising but now it's gone. I would probably cut them off myself if I were you to see if you can handle the drone. If not, then you can add the J-pipe setup from SOLO. It'll cost you about $500.

Hear's my muffler & resonator delete. The car sounds fantastic with VERY LITTLE drone or decel popping!

All The Best,

On a LS3 it is wonderful, on a L99 not so much.
I LOVE my Solo/J-pipe sound and feel. (and they have one for convertibles so clearance is not an issue).

I thought it sounded fine on my l99

I'm going to ask you knowledgeable folks to enlighten me. If the muffler delete improves the sound, reduces weight, increases exhaust flow & has no effect on emissions, why are they there in the first place?

:dizzy:
