Hey everyone! Spent a year or so researching exhaust after I got my car. Thought I’d add my feedback and continue to help others as you have helped me. My NPP was nice for a year, but just not enough growl for me. I chose the 2M as the feedback has been good, love the design (makes sense for flow/equalization reasons) and the price leaves me with $ left over for a intake. I ordered it on a Sat and got a ship label right away with a delivery date 7 business days away(like they commit to on website). It was on my doorstep 5 business days later on that Friday. Bonus points! Exhaust was packed perfectly, looked great with outstanding welds. Install took awhile. If you’ve done this…you know those two 10mm bolts inside the rear fenders are a true lesson in patience. Due to clearance you get like 1/674th of a turn each swing of ratchet/wrench or whatever you’re using! 😂. I wrapped my pipes with DEI Titanium. Used almost 100’ and many stainless ties. I wanted a bit of extra heat protection and really like wrap because it just flat works (check out the Engine Masters episode where David Freiberger proves it). Hit the silver heat shields behind the tips with some flat black header paint. You all know the sounds from the clips, but WOW! The car comes alive but not overly so much. Just perfect. MUCH deeper across all rpms and very civil at highway speeds. I can now blip the throttle and smile. NPP was just too muffled for me. Great Saturday project, enjoy!

 

Congrats. I ordered the same exhaust. It arrives next Wednesday.

 

Yep I ordered mine too and should be getting in installed this week. The price is much closer to what I think an exhaust should be.

 

Have you put the car into V4 mode to see if there is drone? And to see how much difference there is between stock and new exhaust in V4?

 

Agree and why I went the way I did. $1193 shipped with 4 simulators. 👍🏼

Rainy in Michigan this weekend, so haven’t really tested it out much. Did a 20mi ice cream run last night and didn’t even notice the V4 sound. Cruising at 65 it sounds like a stock NPP. Get on it it’s a bit louder in the cabin…in a good way. Get off the pedal and it’s quiet inside again. Best sound is in manual mode cruising through town at 35mph. Really sounds good now when you hold a gear, like 3rd, at low speed. Startup’s aren’t loud, like a sharp bark where you squint and it hurts your ears. It’s really a deep, throaty roar that the videos never seem to capture. It’s pretty intoxicating and addictive. It finally sounds like it looks! You’re gonna love it!

 

Sounds great, the on line videos do make it sound more deep and throaty, glad to see it is like that. No check engine light? Did you have to do a AFM relearn? Thye say the simulators should prevent from having to do that.

 

No check engine light, no relearn. Fired it up and it was mint from the get go!

 

Just had mine installed Monday and no CEL's at all. The valve simulators worked perfectly. Installer said the exhaust was well built and sounded better than others he's installed and he's installed all brands (Borla, Corsa, AWE to name a few). He couldn't believe what I paid for it. He also mentioned the weight savings has significant which is the norm for most systems anyways.

The sound at cold start is crazy loud. Especially inside my garage. Low RPM throttle is very deep and pretty loud. Can be a little dronny sometime between 2500-3500rpms. At highway cruising its mellow, but louder/deeper than stock. I'm now driving in Manual Mode more often as it sounds like crap when in V4.

I do not notice any performance gain from the seat of my pants but didn't expect to. The sound is what I was after and now it sounds like a proper big V8 American muscle car!
