Brand new 4 inch Mufflex exhaust with magnaflow muffler
I have a brand new Mufflex system I bought a few months back but never had a chance to install. I decided to go another route with my setup, so I won’t be using it. Sorry I don’t have any pics at this time, but here’s a video a made when I picked it up. I think I paid around 700 with shipping. Asking 550.00 local pickup. I can ship it out to you but the box is rather large so I’ll have to get a quote.

I know what you mean.. I bought the setup monthsss ago and I’m still not ready to work on the exhaust yet. If you really plan on going with this system I can do 500.00.

Re: Brand new 4 inch Mufflex exhaust with magnaflow muffler
cool. yea, unfortunately I would say keeep it for sale here and sell it to whoever can pay you the price you want for it. its going to be months (february/march 2020) before I am at the point of upgrading the exhaust. if for some reason your setup doesn't sell, I'll reach out to you about it. I feel someone will scoop it up though because its a great deal on a brand new exhaust. thanks though.

Re: Brand new 4 inch Mufflex exhaust with magnaflow muffler
Sorry, I decided to keep it. I’m not gonna use the 4 inch muffler, but I decided to use the piping through a smaller muffler with a cutout. If anyone needs a new 4 inch magnaflow muffler, I have it!

I've been considering swapping out my spintech for a magnaflow. What're you looking to get for it?
