Here is an honest review plus a video with a tunnel run and vibrations shown at the end:

First and foremost, I did not go Cobb or Mountune for a few reasons. Reason one being that you have to take apart part of your old mount to install the new. I see that as cheaping out. Reason two is that they have been known to over break-in. The materials they used are not much better at handling heat than the stock mount, and the mount is very close to the catalytic converter.

I ended up purchasing the CP-e mount. To me, it seemed like a good balance between the Cobb/Mountune and the Boomba. The Boomba is nearly a solid mount. Installation was easy, and it does break in after a few hundred miles. I’m over 1,000 miles in and there still a lot of vibration at idle and low rpm, but mostly just when the AC is on. Those who say you won’t notice it are full of shit. Driving has definitely changed. All of the motor smacking is gone. Stopping is easier, as 300lbs of engine isn’t leaning forward. Acceleration is also vastly improved due to the improved grip. One thing I did not expect but got, is more torque steer. Overall, I definitely would do it again, but it definitely does mess with the NVH.

Around 55 seconds is when you start to see the hood shake, if you want to skip the tunnel run.

I have a moutune mount, I quite like it. What mods/tune do you have?

I’m sure the Mountune is fine, but having to take the mounting bracket off of the old one took it out of the running. Currently I have the RMM, catback “exhaust”(straight pipe), Green Filter, Stratified flash with crackles, and an FS Werks short shift plate. Up next is an intercooler, probably Depo, unless I can get a used CP-e for cheap. Then downpipe whenever my tune destroys the stock cat.

Nice! What colour and seats?

I have (Mountune everything): MR230 pack and tune, RSR brake kit, radiator, RMM, quick shift.

Ultimately this is my weekend car during the summer.

Kona Blue over Molten Orange Recaros!

Nice! I like the Kona Blue’s. In Canada we don’t have a choice on the recaro seats (not that I would have skipped them).

I don’t think I would, but the deals you can get on a new one without one would be hard to pass up. I found one new for under $16k US.

I keep hearing that I should do this, but I don’t think I’m going to want to mess with my NVH. I haven’t had any issues. Yet. So we’ll see. I do think I want a louder turbo noise though. Nothing crazy but I love hearing it. Hmm.

Wow, that’s insane. It’d make a great racecar at that price

I’d use a used one for that. I’ve found then for under 10k.

If it makes you feel any better, I have no new rattles. I’ve just got seat massagers now. It very much worth it.

Also, a drop in Green Filter will add a bit of turbo noise. I have one. If you want a little more grumble, I would do a resonator delete. It’s still quiet, but you can at least actually hear it. It sounds really good when it’s cold.
