For the guys doing Waterford. You will need a muffler there. (Whether you make sound limits or not. It's the law. ) I have some Supertrapps in stock. http://www.supertrapp.com/product_se...t.asp?CatID=27

I am cheaper than those prices.
1.75 and 2.0" OD's. Let me know if you will need one and/or if you need a different size. I will just bring them to the track. We will be doing the Friday practice day so I will have them there Thursday night. (Assuming you order one.)
