Project M3: V8 noises and kid seats

[D_Eclipse9916]

Bimmerworld Exhaust update: it sounds great outside the car but above 4k rpm the Exhaust goes silent. It’s very odd, since it’s just loud enough for me between 1500-4K but where is my 8k Exhaust note?!?!?

Since I am limited on options staying in stock class (axle back only); I had my friend come over with his “ACM” Exhaust mod. Zero drone but is actually much louder than the BW race Exhaust above 4K. Bonus: Completely quiet at cruising speeds.

So I picked up an OEM Exhaust and going to cut open and weld it up to do the ACM mod. Then I will build a straight pipe section to replace the muffler with a quick disconnect for when I do national level autocrosses 4x a year.

Also changing up tips to just slightly larger and my inner ricer is begging me to do the burnt tips when I got sent options for the Cyba tips.
