Project E46 M3: Part 15 – more exhaust testing and weight reduction


Here’s one last close-up of the welds at the resonators on the Megan Racing performance mid-pipe.

Here’s that unique, one-resonator setup on the factory Section 1 that we’ll be replacing.

On the baby scale, the factory Section 1 weighs in at 14 lb, 1 oz (14.06 lb).

Because we’ve doubled the resonators, you actually pick up a pound with the Megan Racing section 1, but that’s a small price to pay for having double the sound muffling.

On our baby scale, the factory Section 2 weighs in at 21.4 lb (21 lb, 7 oz). What? Did you think I was going to give this baby scale away after our girls grew out of infancy? Heck no. In fact, I was rockin’ out to Rock-a-Bye baby music as I shot this picture.
