Megan racing supremo - test pipes vs catless xpipe

Hi All - Maybe a long shot but I'm hoping for some real world experience with an exhaust setup. I'm drawn to the Megan system due to the cost and the good reviews I've seen. Specifically the Megan Supremo (dumb name) exhaust. The car is an E90 M3.

For some reason all the videos and reviews I've seen combine the Megan exhaust with test pipes. I'll be honest, I don't even really know where test pipes go on this car. Do they delete the front cats or the secondary? Either way the Supremo/test pipe combo sounds great to me, especially for the money.

My car, however, has a resonated Fabspeed secondary cat delete x-pipe already installed by the previous owner (all else is stock). From what I understand the x-pipe does a very similar function to test pipes. They're both deleting one set of cats right? Can I expect that adding the Supremo exhaust to my fabspeed x-pipe will sound the same as all the test pipe/Supremo videos I've seen? Anyone have a similar set up to what I'm considering? I'm looking for more volume but don't want it to be too crazy or obnoxious unless I'm getting on it. I also prefer something more unique than the typical deep American muscle sound. Thanks!

Op: Makes fun of an exhaust name because words are hard…

Also OP: What are these uhhhh 'test pipe' things I keep hearing about and where do they go?!?!!

Shhhhhhh shhhhhh, quiet sweet sweet dumb M3 owner, it's gonna be ok. Go here first; ** M3 Exhaust Video Compilation Comparison (9 exhaust systems) ** https://www.m3post.com/forums/showthread.php?t=328915

Now go to the top right and type "Megan" into the search bar and be amazed! The first 6 results have videos.

No no sweet summer child, your thanks is not needed this day, for I come bearing knowledge, and your education is it's own reward!

Wow you're a douche. I could go point by point through your post dissecting what a douche you are, but that would be a waste of my time. One too many drinks last night Duke? Feeling bad about yourself and needed to pump up your ego a little? Help is out there if you need it. If a random stranger saying they think a random exhaust has a dumb name sets you off that much, I feel bad for you.

I have searched YouTube and on here. I haven't found a video or review of someone who paired the Supremo exhaust specifically with a resonated, catless Fabspeed x-pipe. There are videos with Supremo and other x-pipes but it doesn't always specifiy if it's catless and/or resonated.

For example I found this thread last night and the third video is with a fabspeed x-pipe but it has HFCs whereas mine is catless.

A: You have a stock catback muffler and a resonated fabspeed x-pipe. A resonated x-pipe does just that, resonates the sound. This specific x-pipe from fabspeed means it has only deleted the secondary catalytic converter.
B: You still have your primary cats, meaning you are in fact NOT catless. The secondary cat removal only slightly helps with tone since the fabspeed has the resonators installed. (They sell them straight with no resonators.)
C: Since you still have your primary cats and only a simple x-pipe, your sound is going to be on par with many individuals whom have simple x-pipes paired with a Megan Exhaust. The exhaust is going to give you the loudness based on your setup and the x-pipe will only add tone/richness in your specific case.
D: We have dozens, no....hundreds of posts on exhaust setups, catless vs. catted, x-pipe vs. x-pipe, etc. hence why you should have used the search functionality (or google ffs) and came better prepared when asking questions.
E: Supremo in the English language means the "top ranking or top authority"; Megan has most likely named it this because at the time, this was the most expensive exhaust for a high end car they had. They make dozens of lesser models for other vehicles; Toyota, VW, Scion, Hyundai, Honda and for much cheaper.

My sincere apologies for making those points and I hope your ego will recover in time.

And remember; is your friend!
