Received my M4 exhaust from Mr. Greg Spears and Spears racing. Cant wait to put on this weekend! Will update with pics.
We can do a sound comparison at MSRH.M4 has some great products and great people too! I was holding out to get an M4 pipe on my R3 but ran out of patients and got the Ti system from Arrow instead. Not a week later and the M4 systems are available, look better, include a canister hanger and cost less. I'm still kicking myself!
Next time I will be more patient...
