I have them both here in front of me, and. they are identical in configuration. the evo being ti & the race being stainless. Both have the tapered mid section, and are 4-2-1 unlike previous 4-1 systems. You have a choice of ti or carbon cans. As far as fitment they are usually awesome. but ill let you know this evening.

Hey SHRAKE sorry but you need to reaquire your data. I believe you might be mixing up some pre 02 stuff into the comparison. If you check lockhart part #s for the YZF 2002 they are as follows. 424-6762 for the carbon evo titanium. and 424-6517 for the carbom race stainless. You will find they both come with identical canisters Part #M-TCE2. Please let us know how you came up with the dimensional differences. Im wondering if they have a third exhaust that the mid pipe has a constant cross sectional dimension.
