I love short, loud pipes. I had Samson Boneshakers on mine, they rocked but kept breaking up near the exhaust flange. After Samson replacing them 3 times they told me they were discontinued. I got a set of Grumpys at Myrtle 2 years ago, I really like how they are short and fat (2.5") and they sound great, but they keep coming out of alignment so now I'm looking for something new. A guy at a show last weekend had an awsome 2 into 1 similar to Keim's LMF and sounded awsome, but he said it was made by Martin Bros, but when I looked I couldn't find it online. I'm looking at Stainless Creations Octane crossovers, they say they can do them short and with a slash cut. My buddies Bourget has the Exotic Choppers Punks. Really cool pipes, but don't bother paying for the ceramic coat on the inside of short pipes like he did, I don't think you can get the bike tuned well enough to avoid some bluing.
