Ignore me and stick with Andy’s advise

I’ve only played with high and low sweep pipes on MC18’s and as Andy rightly points out the 21 has the more modern / kinky back end with completely different pipe routing.

I just think it would be an inefficient way to go about things, especially given how good the OEM chambers are. Swapping R2/4J and R5/6K pipes isn't a big deal, but I think 88/89 to 90~93 would be quite significant in both terms of physical effort required, and expansion chamber working dimensions.

If a race pipe is really desired, it's definitely worth just scouring the various auction sites, placing a wanted advert in the Classified Ads here, or just buying new from TYGA (if they're still producing them).
