M2 and Magnaflow Exhaust Build
I just purchased the M2 HKS Replica Exhaust from Megan Racing along with an X-Pipe/Muffler from Magnaflow. Borla makes an x-pipe/muffer but I think it's a .5 inches too wide.
I'll be sure to post pics when we cut to H-Pipe to see the integrity of the exhaust system (any flow blockage). Due to the design of the system we will be cutting behind the H-Pipe and cleaning it out as needed. If we can cut in front of it then we can eleminate it all together. Just looks a little tight in that area. That's why we went with M2 instead of another knock off because the design fits a little better for the modification.
It's a 2.5 inch system so I got the 2.5 inch X-pipe/muffler. I'll be sure to post pics and video of the build, exhaust notes/tone using stock, full system no x-pipe and full system using x-pipe.
I do have a Inject CAI so we will see how she turns out! I'll keep this updated as parts arrive and work begins. Any preliminary suggestions? Other then that stay tuned.

THe x pipe brings back the Z gurgling sound. It also quiets down the system just a tad. To be honest it sounds more like a Ark exhaust system, you know the guys who made it a big deal they have an X pipe welded in instead of a H pipe.
Have you done research on what benefits a X pipe vs. an H pipe does?

For my build I'm going more for sound and not necessarily #'s and the x-pipe does a much better job with sound then the h-pipe. The VQ sound is amazing and I don't want to loose that.
If I was going for #'s I would leave the system they way it is, test it and start from there. As a matter of fact I wouldn't have gotten this exhaust if I was going for #'s lol
It's all about looks, sound and some positive gains at this point in time. If it's 0 hp gain, which I doubt will happen, and an amazing sound I will be smiling ear to ear! But if it sounds like crap when I'm done I will be through the roof!
Here are some pics of the x-pipe

should change exhaust note [deeper] and MAY move over the tq and/or hp curve.
I wouldn't be surprised if gains are made, but gains would be minimal...
I did the magnaflow X pipe muffler mod when I had the STILLEN exhaust [replaced STILLEN x pipe with magnaflow "x muffler"], but I also deleted the STILLEN resonators [didnt see a need for them seeing how I was adding a "x muffler"]. The car pulled harder and sounded deeper after this...it also did a gargling sound on decel...VERY NICE
Id suggest deleting the resonators that came with your exhaust, when you do the x muffler mod. You wont get rasp with them gone

ALSO:
if your replica exhaust is like the HKS, the rear "Bung Resonators" will be impeding flow.
On the HKS, where the "Bung Resonators" mate with the main exhaust pipes, its pipe impedes the flow of exhaust a substantial amount because they didnt notch [half moon cut] the "BR's" mating pipe prior to welding....they just cut a whole in the exhaust pipe, slid the BR's pipe in [which has a straight cut] then weld the 2 together.
Id suggest having the "Bung Resonators" on your exhaust cut off, notched, clean the whole on the main exhaust pipe of slag, then weld the two back together.

Bikinilust-deleting resonators for less rasp?? I took mine off and now have rasp x1000 at WOT

^ not sure why one would want to do that, but all I know is my borla with no res is raspy as all hell. Stock cats. Im about to either put the both res back on or buy a resonated h or x pipe to subdue the excess rasp.
Maybe the stillen is different by design than the borla, or maybe I need to switch to x pipe. Im glad ive found a cheap welder in the area, because I **** with my exhaust way too much.
edit: Ok just reread it, you ran a x muffler. Cool, we are on the same page here. Any sound clips?

Exhaust arrived today. Took at look at everything as far as quality and workmanship. Pics are attached.
As you can see the H-Pipe is built pretty well and it doesn't restrict flow at all. Welds appear to be in very good shape (flex pipe, h-pipe, flanges and muffler).
As far as the bung resonators, I am not going to mess with them. The H-pipe looks good so I'm sure the Bung Resonators are ok.

H-Pipe looking nice! I'll take some video with the exhaust without the x-pipe muffler and then one with. Should have all this set up welded up and one by Thursday and Vids by Saturday.
I would HATE to turn the car on, hear the exhaust, love it and not put the x-pipe muffler on! But we will see. I'm impressed with the construction of the exhaust and if it sounds the way it looks...the above might happen

But yeah the M2 without the xpipe sounds more on the muscle car sound. It a glug glug glug sound but with the X pipe its quieter with a humming noise with the Z note back to life.

Update
Exhaust has been installed and I should have some vids up very soon. Did have some alignment issues with the right side but all is well. Its below freezing here in MD and the Ravens are on so I should have vids up by the middle of the week.
I did not have the x-pipe installed yet. I am also looking at the Berk HFC and that is when I will more then likely have the x-pipe welded in to eliminate the rasp I will get.
Car is def faster, has a deep sound in the lower revs and then brightens up in the upper revs. You can hear the VQ note from 3.5k to about 5.5. Drone in the car is ok with me but might not work for others if ur not used to driving a car with exhaust everyday. Every car I've ever owned gets exhaust with in a month...no matter what it was! lol
