5/29/2021 Edit: Added more pictures prior to the installation on page 2 & the bottom of this post.
These are installed in conjunction w/ the ER secondary catless downpipes. Big thanks to jsnkim, RG Sport, the Stance Shop & Alan I!!!
Myself, along with other F95 & F96 owners found the stock US setup somewhat conservative and not up to par with the rest of the M line-up. These comparisons include (but are not limited to) the F90 & the F97's.
Merely swapping the secondary downpipes to a more-freelowing solution simply is lightly scratching our itch. The increase in depth is barely there, but the change in tone is not a day & night difference in my opinion.
The next intuitive action is to upgrade the exhaust. Albeit at a dear cost. I took possession of jsnkim's exhaust, simply because he doesn't have time in his busy work schedule to install and enjoy it. After very much going back & forth, I agreed to take it off his hands. He's a nice guy at first impressions, but an even nicer & thoughtless guy as a friend!
I also want to give Alan I a warm shout-out, for also truly being selfless & generous with answers to my questions, tips & tricks along with his valuable feedback!
First off, the exhaust sounds more deep, throaty and louder than the audio suggests. All the shared clips were recorded on an iPhone 12 Pro Max. Cold starts are significantly louder, to say the least. The throttle set to Comfort yields more low end sounds, especially leaving the trans in 3rd gear, cruising with light-medium loads. As Alan I remarked, the sound is definitely exotic and less cheap-sounding (no snap-crackle-n-pops).
In Sports-Plus, the sound is definitely more louder - in a tremendously, wonderful manner. Our cars move a large volume of air though the exhaust, and the physics in-action are heard in a great way. In motion & leaving the car in-gear, medium-high load makes the exhaust shout without popping or any high-pitched sounds. Its on the high end of the sound spectrum of what's acceptable without being too much or obnoxious for sure. A quick lift off the throttle usually results in a nice backfire as heard in one of the clips below.
With the valves closed & in a higher gear, my configuration definitely flies under the radar. Zero cabin resonation & no exhaust drone when warmed-up
& at idle. Originally I wanted to also install the center pipes, and that's yet to be seen if it's truly necessary without being too much.
I hope these thoughts were helpful. Please let me know if there are any kinds of feedback or questions. Thanks for reading!
