Budget was $250 (living off loans and savings). Aftermarket exhausts that would require modifications would run $1,100+ (NM Engineering, Dinan, JCW Pro). I’m probably going to sell the X1 in the next year and a half so that was another consideration.

Muffler is still seeing exhaust flow, the added pipe is wyed in, didn’t clarify that. I’m going to run downstairs to record a cold start with the setup and post video clips up afterward so others can see the difference for the minor investment.
