I assume this is part # M-9430-GTX. That sounds the best to my ears and the most like the original race car (FYI the Duke Publishing video has a test of Ford's museum GT40 and it sounds like this, just fabulous).

That exhaust system is listed at Ford as "not for street use". What I'd like to know is does it eliminate the cats altogether? If so does that mean you need to recalibrate the ECU or make any other adjustments? Also, can the owner of this car or one like it provide decibel levels at various RPM comparing it to stock? Because that exhaust sounds fantastic to me but if it's so loud that it's undriveable in the real world I guess I'll have to go another route. I love my stock car but the fact is, its too damn quiet sometimes. As the hog riders say, "Loud pipes save lives". :wink
ford has the borla exhaust that is street legal and not street legal, its just not listed... if you ask for it, but they do not have tubes or headers that are

However - the question of whether it is "Street Legal" is not whether it will be caught, but rather, "Is it an approved device?" And there, if it has not been submitted for approval and passed, it is not legal. This is the only possible answer to the question posed.

Oh, understood from the get-go. I'm just sayin' it's highly unlikely there'd ever be an issue unless 'Fast said, "Oh, uh, by the way, that muffler isn't the one that came on the car!" :wink

So I guess I'm out of luck in finding an exhaust that is 50 lbs lighter, but has the stock sound level. :frown

coming to the wire re exhaust decision. two finalists are Stainless Works headers or Stillen exhaust w/ stock headers. Talked to timcantwell-great guy and good info. Last step is to talk w/someone who has the SW system. Anyone w/ the SW system please give me a call: 615-533-9368. I'm in desperate need of ear candy. Thanks in advance.

Muffler Drone

I just installed the Accufab X pipe, but the bass drone inside the cabin between 2,000 rpm and 3,000 rpm is incredibly loud and painful---ears hurt for 24 hours. Tried ear plugs and got some relief, but still felt it later. Must be a sympathetic vibration transfer. Has anyone had this problem? It seems to me that sound deadening material such as Dynamat on the inside of the bulkhead/firewall might help this situation. Otherwise, if I can't install some baffles to eliminate this, I will have a beautiful sculpture to put flowers in.

We have spoken

Now the next conversation I suspect that it will be when we are working through the installation together

It was my pleasure

All the best

The stainless works are really loud. You can almost knock people over when you go to WOT in neutral. I added vortex cones before the Cats. I find it still a little loud, but O.K. for driving in general.

paul b, thanks for the input. Really loud is OK. Years ago I used to go bowling so knocking over a few people sounds like a hoot. I have a really high thrill threshold.

How much of a difference did the Vortex cones make?

This is the 1st I have heard of the problem. I know another owner with a Accufab in my area I will have to hear it for myself and see. I am planning on getting Accufab, Ida, or Heffner system. The main reason would be to drop 40 or 50 pounds off of the back end. The Heffner is in the lead, because of the tips and replaceable baffles.
