Everyone seemed to recommend the center in/out resonator. I can easily get the offset, I thought that is was straight in/out.
I wish I could do a group buy or something. He is a manager of a Jeg's distribution center and gets an employee discount. Buying stuff here and there, OK. Buying 100 of the same muffler - suspicious and would probably get him fired. He has to clock out when he goes to the bathroom!
On a cooler note he raced 400 cc bikes for like 10 years, and now has a 900 RR with like 170 rwhp which will blow your mind. Now I want a bike too.
