Hey guys,

Just wanted to say I recently changed out my exhaust due to a very strong exhaust leak. I've purchased a Megan Racing Y Pipe, The full Topspeed Y back exhaust, and a 2.5 to 3 inch adapter cylinder. I have to say I am very happy with the sound. It is quiet and there is no drone. If I really want to hear something, I'll have to press the on the gas heavily and I'll be able to hear something from 2k-3k rpm. That is all and good luck!

What's up guys. I'm having this huge tinny issue with my motordyne exhaust / z1 hfc . I guess it's also my fault cause I haven't looked under my car thoroughly yet but from a quick glance, everything is fine .

What happened is whenever I'm driving between 2.5-4.5k rpm , I get a tinny noise upon acceleration . I can let go, accerlate, let go, and accererlate, and as long as I am in between 2.5-4.5k, there's a 90% chance the tinny noise is there.

It's only on my passenger side, coming from literally where the door cubby is (where you put that 1 bottle of water and a bunch of misc. Items) . I noticed it's not as loud when I roll down the window a little . It almost sounds like my gasket holding my cat is loose, but I'm not too sure .

Here's a video. Any suggestions would be great. I'll eventually go to an exhaust shop to put it on a lift and see, just seeing if the community had any knowledge of it first .

That's what I initially thought. I'd just take it in like you said and make sure everything is tightened up, gaskets are good, and nothing is rubbing against a heat shield.

Hello, I was wondering if you could please tell me if this is the same exact J2 exhaust system. I own a 2013 G37 Sedan non all wheel drive, just trying to make sure before I purchase. Thanks for the help.

My 6MT which I've had for about a month came with J2. The mufflers are rusting yet most of the rest of the underbody is rust free. Not sure why, but something to watch out for.


Anyway, whats everyones thoughts on Ark vs Motordyne?

Do you guys know if the ark grip catback will fit my 2011 g37x??

I actually think Ark is interchangable between AWD and RWD.

I don't think so, that's why they offer 2 different ones

I've noticed when my exhaust isn't warmed up, it'll rasp from 4k-5k RPMS. It's the Berk HFC's I assume, so I'm thinking about moving the 12 inch Vibrant resonator from between the x pipe and muffler to between the cats and x pipe. Does anyone have any experience with this? Would it reduce the rasp from the HFC's?

Not sure. I'm thinking it would some,But since you are running HFC thats the main culprit.

Thanks. I think I may try this out, and if it doesn't do anything, save up for some FI RHFC's. I assume those don't rasp at all.

It lists it for both on their site, and the Y-pipe design is usually the fitment issue for ones that do not fit both, and theirs is in line with other y-pipes that fit both. I have a RWD and AWD model and it sure looks like the ARK would easily fit on the AWD (while my J2 wont fit on my AWD due to the Y pipe). Maybe at one point in time they didn't fit on both but I think they have for awhile now. I will be swapping mine over too my RWD most likely but as I said I don't see any issue.
