chopobo, there is no tip inside another tip, what u are looking at is a front on view of the tip, inside the tip u can see the size of the inlet which is 3". the tip is larger than the inlet size. tip could be 4 - 4.5"?
cheers for the replies, i always thought that this style of kakimoto muffler was slightly quieter than the canon ones. now lets stick to the topic, are there any buyers?
