Reviews for Mac 4-into-1 Chrome Megaphone Exhaust System - 001-1401
Where's the Beef???
I really wanted a Performance Header that I could wrap and use any muffler I want. I can do that still. This muffler is a little whiney. Not Beefy! I'm gonna stick a Cherry Bomb on this Header!!! Very Shiny for sure! Nice upgrade. Still doing power/speed tests. I'm getting ready to Pod and Jet! Had to lift the front of the engine to wiggle the tabs into place. Not that hard to install. Yes, you can do it.I would recommend this item to a friend.
Mac 4 into 1 for Honda CB 750K
Shipping was super fast! It was vary easy to install. One the old exhaust was off the new one was on in less than 15 minutes!I would recommend this item to a friend.
Fit was good. There was rubbing on the clamp against my center stand. Fixed it by clamping higher up on the muffler Sound is loud. A little too loud for my taste. I'd prefer stock noise level. Finish was almost perfect. Missed spots of chrome on welds. Overall, a very good product. I really liked that the headers allow room for when performing an oil filter change.I would recommend this item to a friend.
Overall really solid system
Installed on a '76 Honda CB550 and it went on fairly easy, and the finish does look really nice! Only gripes so far is that the center stand bracket didn't really work out. Which wasn't a huge problem because with the old 4 into 4 system gone it kinda looked out of place. Though on my bike it is easy to just slide it back on whenever I need to service it.The finish around the collector welds looks like it might flash rust if it were to get caught in some rain. The sound of the exhaust is great though! Makes my old honda sound like a sport bike. It's definitely louder than stock on acceleration but usually mellows out at cruising speeds. I'm pretty pleased with it overall, definitely cleaned up the look of the bike!I would recommend this item to a friend.
REALLY NICE PIPES!!!
these pipes are loud. even with baffle there loud. i'm planning to take it out but it kinda sounds good with it in there. it also has a wicked sound over 3500 rpm. I LOVE THEMI would recommend this item to a friend.
Fit great on my kz650, bike runs better and feels a bit faster. Sounds a bit better too. Quality is awful though, welds began to rust a week after installation the first time they got some rain on them.I wouldn't recommend this item to a friend.
I bought this system for my 1983 CB650SC Nighthawk the other day and I just love it !! My bike runs so much better and looks great too.I would recommend this item to a friend.
