Legal Bill

Hi everybody in Southern California.

Moderator, feel free to switch this post if I am posting in the wrong club.

I am considering the Spugen single bolt on kit. I want to use this system for autocrossing, but will probably want to leave it on most of the time this summer, so I am leaning toward the oval muffler. I am wondering if any of you who have the single oval system (bolt on preferably) also have before and after dyno results on an otherwise stock car that you would be willing to share. I have asked Duc to send or post some results, but he must be busy with other things right now, so I thought I would post the request here and ask some of the customers. I have searched many threads on this subject, but I can't find any dyno results for the single system

Thanks in advance for your time.

Bill
