I’ll probably add a pipe dynamics res delete next month, weld on quad tips and be done with it until I can afford a dahhler or super sprint axle back.

Alright you sold me. Downpipe next..

Just don't go with catless dp - the smell of exhaust fumes is unbearable.

Plus, I’d love to get the HPs above the 4-Hundy mark… just a tad more “punch” than stock.

Will prob end up just leaving it as is… I’m getting old and cranky these days.

When did exhausts get so dang expensive? On the E9x you could pick up a BMW Performance Exhaust for about a grand. I got one used off a forum member for $650. Loads of improvement in the sound department and no voiding of warranty. Also sad that BMW can’t do that anymore with new legislation.

The new LCI X5 allows the selection of an "M sport exhaust system" as part of the M sport pro package... what does that mean vs performance exhaust? beats me, but perhaps a bit louder
