Axle back exhaust group buy: for the people, by the people.

[Nobuseri]

I'm sure it's nice but for 12-1300$ landed I'm not so sure.

If the right shop is doing the work, custom >= off the shelf.
In this case for potentially half the price.

Keyword "if" but to each their own I guess, a tuned exhaust of established brands outmatches any "custom shop" by miles away.
