X5 passenger side exhaust valve

Any of you guys tried the golf tee/zip tie mod like they talk about in the X6 forum?? wondering if it really sounds that much diff or makes a change worthy of doing it

FWIW - I tried it last night, definitely notice a little rumble but felt less push from 1st gear 1-2krpm off the line.. dont know if my mind was playing tricks so i cut the ziptie and the low end torque came back. not a bad little tweak to the exhaust though.

Passengers Side I believe... OP can confirm... Your right on the apparent loss of tq on the low end. I've had my flap completely removed. But a Tune more than makes up for that apparent loss...
