Ehhh - its an exhaust if you need one

Well, the fit isnt great. The flanges of the header bottom out into the aluminum head. My baffle leaked immediately and had an obnoxious rattle. Also had to ditch my center stand because it bumps into the pipe when you try to put the bike on the stand. The pipe also touches the oil pan. So...still want it? Its embarrassing to ride around with it sounding like that.

Mr

Superb product at an affordable price, rated as 5 on all accounts except sound. I'm currently looking at extra packing or maybe some type of insert to get rid of the crackle/pinging noise at certain RPM, no big deal, great pipe overall

All Black 4-2-1 Sys for my 84 Nighthawk

The system fits and works fine. I had to add packing in order to fix the cackle and frap F1 car sound at 3500 to 4000 rpm. I wrote a real review but 500 characters or less wouldn't let me post it.

flanges are warped

This is the hardest header I have ever tried to put on a bike. Went thru 6 sets of exhaust rings, finally had to take a hammer and straighten the flanges out then sand all of them down flat to get it to seal off. Product would seal off then start leaking after about 30 miles. I now have blue pipes instead of chrome because this would not seal off.
