I just installed a ultimate racing dual tip cat back with the mini mullfer mid pipe on my evo x this past weekend and here are my thoughts on it. the fitment was great. only issue I ran into was getting the stock heat shield of the danm cat so that I can pair up the new exhaust to it. Sound wise it sounds very nice but way to quiet for my taste. it's just a little louder then stock when warmed up idling. coming from a 350z with an Invidia n1 exhaust, this was nothing compare to that. Should've gone with the resonator mid pipe. Pics and video will be post later on.

 

I would recommend coating the flanges with anti rust coating. The piping held up really well for me in the rust belt but the flanges were corroded to the point where it was flaking off in pieces when you touch it.

 

review with no pics.... :-(

 

Here's the pics and video.

Btw my stock exhaust is for sale if anyone wants it. Has about 2000 miles on it only, practically brand new

 

nice dude. sounds mean

 

Thanks man. Wish it was a tad louder though. Regret not getting the resonator version but it's all good.
