I am close to purchasing an m2 exhaust system for my coupe but yesterday i stumbled upon this. I also plan on adding the magnaflow x pipe to reduce drone but anyways what do you think about this exhaust.
There is also a sound clip at the end of the installation video

Like all replicas of the HKS exhaust system, it's just a cheap copy of what is one of the best exhaust systems available for our coupes. Funny the vid mentioned nothing about installing the gaskets between all the flanges, guess they assumed you'd know to do that. Installing a Magnflow X-Pipe was intended to remove the crossover in the real HKS system, has nothing to do with removing droan....Gary

 

idk about that. I heard there were problems with the pipes not matching up in the HKS. Also if its so great why would you remove the crossover to install the magnaflow?? On the knock off its to minimize rasp and does help with drone.

 

I had an x02 on my car for years and I really enjoyed it and had zero problems with it, I would definitely buy it again. I personally would never spend my money on an HKS, especially when the piping diameter has found to be inconsistent by some owners, and even though there hasn't been a ton of testing, the small amounts have shown the x02 to have higher gains than HKS. If you really want performance and top notch quality go for MD.

 

There's no fitment or rasp issues with the HKS. And I can't remember there being any drone either. People replace that section to reduce the restriction.

The X02, which is an HKS replica, is good for the price. I haven't seen any other replicas in person so not going to comment on those. I'm just going to say there's a lot of exhaust systems out there that sound like ****.

 

I have the x02 with the magnaflow x-pipe...not too much drone...and no rasp at all...I love it
