Hey guys I'm new to the ltr 450 and kinda in a pickle with selecting an exhaust. I have been looking at the dasa or curtis sparks. My ltr has a yoshi cherry bomb, and the lid removed. I will be purchasing an air filter when I buy an exhaust. The sparks exhaust worked really well on my 400ex, but many people say dasa is better for the ltr. Just wondering what you guys think of these two exhaust. Thanks in advance.
