mac 450 exhaust
so the po of my 450 chopped and removed the baffles from the exhaust. due to the legality of this i do want to make changes, the only aftermarket complete exhaust i could find is the mac exhaust https://www.ebay.com/itm/MAC-Stagger...whXdc34vK#rwid
about $300 shipped. seems reasonable... anyone have this specific one on their bike? open to other suggestions if anyones got. not looking to go back to stock, i like the opened up sound.

I rode a 450 with those. Definitely louder than stock. Be careful if you get them, it's very easy to get burned on those pipes!
Keepin' all the left over parts. Gonna use 'em to build another bike!

I chopped off my mufflers and replaced them with slip on mufflers. I have a 450. They have baffles of some kind, sound louder than stock, but not raspy or annoyingly loud, just a deep bob bob bob bob type of sound. Bikes drives well, didn't need to rejet or anything so far. Cost me about 100 euros for the pair.
Because they were cut where the mufflers weld to the head pipes, didn''t have to worry about any studs breaking in the head, or pipes re-routing and burning legs!

I had a slash cut, non-staggered set and liked them, good quality. Can't find an old pic of them, sorry. They are louder, but do sound nice, not chopped and raspy. The 450 sounds ok when you go with straight/open exhausts. I was informed that there is no need to change needles when modifying exhaust only when you modify the intake, so have not done.
I did not like the single sided look for the bike when I had them on, so went back to OEM. Also, they are single sided, so will change color slightly immediately upon use, but if you are not running lean, it won't be too bad.
Working on fishtails now

I have cut pieces of wood so I lift on the frame with the jack like you have.
This works for me.
Good luck
