Rumbles and Burbles of C8 Corvette With 2M Fabrication Exhaust

Low speed sounds of the rumbles and burbles from the 2M Fabrication Exhaust on my 2021 C8 Corvette.

Hi there. On your install video of that exhaust you mention a little concern of how close the X pipe was to the plastic under the car. Did you have an issues from that so far. ??

[@SerhansGarage]

No not at all. That piece just feels a little warm after a long drive, I have no concerns with heat at all

@@SerhansGarage thanks . I’ll be picking mine up this week . Still waiting on car but I’ll have the exhaust ready to fit when the car comes at least.

What's that sound like inside car!

[@SerhansGarage]

Sounds amazing. No drone and in track mode it has a high pitch exotic like sound.

2M Fab sounds awfully good, but I promise you the MBRP is even louder, deeper, and more aggressive! Cost is basically the same and comes with 4 simulators and carbon fiber encased tips. 2M has inline resonators, whereas the MBRP is open pipes throughout. Rev battled the 2M/Paragon Touring/with resonators a few days ago, and the difference was clear. Both sounds good, but the MBRP was euphoric!

I considered MBRP but I was worried of drone being a straight pipe design. Like you mentioned the 2M has resonators - these are perforated and that helps reduce drone. 2m may not be as loud as a straight pipe 'track ' exhaust but it's loud as it is - I don't want the car to be any louder than it is. I'm sure MBRP sounds good, plus it's Canadian , ultimately I think it would have been too loud for me and droney.

@@SerhansGarage .. And I can tell you I cam e within an inch of buying 2M myself! I looked long, and longer trying to find the right one, and the battle was between the two. Your 2M sounds very good for sure, and sounds much like mine except I have a bit more volume wide open, and a great bit more on cold starts. The cold starts had me really worried, but so far the neighbors haven't complained, and I never start the car in the early mornings and only drive it every 3 days or so. Drone? ... I don't have any!!! ... nope, I don't have any! All aftermarket, none NPP exhausts have that funky V4 mode sound that no one wants. I almost never allow mine to go into V4 by keeping it in Sport mode or Zmode with Sport settings when at low speed. It wants to to to V4 at 3rd gear while in city streets 20 mph or so, and that's where it sounds funky, but again, I never allow this, or pretty much just hit the M, manual button which shuts off V4 mode entirely at all speeds and gears. But, finally .. anyone who is rocking with their OEM exhaust, .. even the "Performance Exhaust" from the factory are being cheated out of the most fun in having a C8. The optional OEM NPP exhaust simply doesn't measure up as you know. Can't go wrong with either setup here. 👍🏼

@@Stew5166do you recommend MBRP for someone who has NPP on? I just don’t like how the valves become non-functional

[@Stew5166]

@@bezaldo7 I don't know how to answer that. My car never had NPP, and I don't know how important working valves are to you? The startup when cold is somewhat explosive, but it quiets down in about 20 seconds to a real nice lope! ... Just got in driving mine, and I KNOW I made the right choice for my super quiet non NPP car. No neighbors have complained, but I don't start mine everyday, and I never start up before 8:00am. Aftermarket systems with valves cost 3 - $4,000 , and I can't see any justification for this just to have valves working. Simulators for the AFM and NPP valves simply work, and negate the NPP system altogether, ... but just my point of view.
