Have the SRT-Race Knob/Shifter, so don't know about the B&M,
BUT can answer the B&B HEADERS anyway question...also have Corsa Exhaust (AWESOME sound)...and added B&B headers to that. So, you're really not getting the answers you want here, are you??!
Guess you could call Sean Roe and ask him...don't know where you're from, but if you're around the NE (CT/NY/NE) region, you can also ask Chuck Tator/Viper WIZARD from Tator's Dodge (
[email protected])... both are very good at these types of questions.
(roeracing.com for Sean Roe). Good luck~juli
