Billy Boat is on
 

Did this today..took about 4 hours...This was not easy I say an 8 out of 10, 10 being hard...I had to cut about an 1 1/2 off the passenger side pipe before the muffler, bend some of the tin it was hitting (it is tight in places), and re-plum vacuam lines, the flapper on the billy boat are on the inside, factory are on the outside. Love the sound, love the looks, but damn next time I pay some one to install.

Don't lie.... The pride you now have by installing that youself is priceless. And you would do it again :)

I am 45, to old and FAT to be trying to shimmy around the ZL1......:respekt:

Are you running headers?

No headers, yet...lol

Mine is on order...estimated ship date of 12/7...I am excited! I just installed the M2W...and loving it! Would love to hear as many sound clips as you can do!

How much louder than stock?

Scott

Louder on start up, but in the car driving, it seems much tamer than the stock, not loud at all, we did not notice a big difference at all on our 8 mile test drive. I will be able to get more clips up in the morning..just tried right now and Enjoying some Honey Jack Daniels :headbang:

Enjoy on!!!

Very curious if it will have drone with headers. The stock NPP has a very slight drone with longtubes and also gets a little raspy at high rpm's.

I don't know if there is a difference on the 12 to 13 on the exhaust? Like I said the passenger side would not fit on the stock hanger at first, driver side fit fine. I had to lop off X2 different times on the pass side during fitment, all most 2 inches. Also the lines for the stock are hard lines and do not bend, I had some spare windshied washer hose with a t tap, used this to plum from the controller/reservior (not the one from front to back) to the actuators, ran it along the back of bumber and Zip stripped into place. The actuators are on the inside pipes, were as the stocks are on the outside? Tin along the tunnel cover Driver side had to be bent and cooling line on pass side had to bent upwards a little for clearance (did not want so close to pipe). So not sure if there is a difference, my invoice said 2012 ZL1 Bi Modal exhaust?
