Hi. I'm thinking about purchasing just a slip on exhaust (muffler) for my 01 r6. I've been looking around and there seems to be a general consensis that people like to use Yoshimura. I've found the RS3 to be very popular. I understand that the old saying "you get what you pay for" but in terms of just a slip on muffler should i opt for an expensive name brand one or go for a cheaper alternative yet still have the agressive sound. I never knew just buying a slip on muffler can be so expensive. What do you guys recon?
