Very good!!

The craftsmanship and quality of the fabspeed cat is second to none... ML performance were excellent, customer service was perfect and really fast shipping..plus the hand written note within the parcel was a good touch..I’ll be sure to use them again in the future.

Originally posted by John M. on 28th Feb 2018 I installed my sportcat this past weekend. I did it on ramps and took my time and in 3 hours it was done. IF you're a decent weekend mechanic, you may curse a few times but will get it in. If not or just don't want the bother, it's not very expensive for a shop to do it. I love this thing. I can feel a little more mid-push for sure. The sound has really picked up. A stock M2 sounds great. With this thing, you can hear the turbo a bit more and it really gives it more of a growl and scream. I've had my car for about 8 months and while I'd gotten a ton of compliments on it, never about the sound. In the past 2 days since the install, I had a guy track me down @ my desk at work to tell me he was behind me the day before and he had to tell me how sick the car sounded. On my way to work today, a couple of guys in a worked Mustang GT pulled up and told me how great it sounded. That NEVER happened before the SC install. I'm stock besides having a Dinan sport tuner, so this thing is the only exhaust change I've made. My buddy says I don't know how good it really sounds because I'm always in the car. It seems he's right. I did this for the few extra ponies, but the sound seems to be a huge plus on top of those. If you're on the fence, get off it. You won't be sorry.

Original review posted Anonymously on 2nd Oct 2017 Installed the Fabspeed 200 cell sport cat yesterday...my car has the Dinantronics Stage 1 installed (I am saving up for the Dinan big turbo + Intercooler ). The improvement in power with the Dinantronics alone was a mild boost in power in the mid range made more impressive by adding 94 Octane to the mix. The Fabspeed sport cat made for a holy **** bump in power AND sound!!! So thanks to the guys at Fabspeed they make an excellent quality product that rocks!!!...and second, I would suggest adding the sport cat as a stand alone prior to other changes to the exhaust system as it now has an even louder, deeper and IMHO more awesome exhaust note. For me, there is absolutely no need to mod the exhaust beyond this...plus I like the stealth mode.
