Hello everyone. I wanted to check and see if the '04 ST3 DP slip ons would fit an '04 ST4S? I don't see why not but wanted to check. I would imagine the only difference in the exhaust is maybe the flange that bolts up to the motor but I'm not 100% sure on this.

Thank you in advance!

No, they won't fit. The ST2 and the ST3 share the same header size, not the ST4 (or 4S).
