Maybe post links. I dont feel like googling and then reading and then probably coming to the same conclusion as you.... haha

What HD engine ever made could support a 1 7/8" to 2 1/4" header pipe?! haha wow

two bros I ran before. Nice low idle but barks when you crack the throttle. Some people have had issues with the muffler cracking I never did and sold it to buy a bigger diameter pipe for a big ci build l.

very few vids on the thrashin ar exhaust tho the vids that are available it does sound good. Apparently reading the dyno charts don’t look promising as it has a low end dip (forgot where I seen the dyno sheet but it was on ig )

there Are many stainless pipes to chose from I’d also look at fab28, spf, red thunder, royal t, hpi sdc exhaust.Be prepared to pay for a good stainless pipe!

i just dyno tuned a sportster with the Thrashin header on it, looked good, sounded good and made ok numbers. not bigger or lesser than other systems. It's kinda hard to tell for me as the rest of the bike was stock, so hard to tell for sure how it would work with a hot-rod engine, but the curves were good and the power was in the expected ranges considering the stock engine.
