Easy to install

August 15, 2012

This header and muffler took only about 30 minutes to install. Perfect fit on my 1975 Honda CB550K. Matte black finish seems durable, looks good. Gives the bike more of a modern superbike sound -- sort of a nasal growl. I was already jetted 12 points richer than stock, and no further change was required. Takeup from idle is good, and acceleration above 3000 rpm is improved. Very happy with this system.

I would recommend this item to a friend.

Change is sometimes good

July 10, 2011

The last time I had a MAC header on an old Kawi its was already installed when I got the bike, it was also if I remember correct chrome canister type. This was my first install for my current bike, 1984 Kawasaki KZ700, this bike has been kinda hard for finding parts that are correctly listed for fitment, so I took a long time to make this purchase. First, Dennis Kirk great, as for delivery, UPS just sucks. Header came with no instructions and none to be found anywhere on web, my biggest concern was for the collars on the new header, they where part of the actual header, so I was not too sure if it had enough spacing to have exhaust holder seat properly on the exhaust outlet. Took a bit of a twist and pry to get the header to correctly go around the down tube of the front of the frame, I got it around, was able to get 1 nut pack in place, then worked my way from outside to inside 1 flange at a time. Install took maybe 30-40 minutes total time once I got old header dropped. Canister required a bit of muscle to get around collector and twisting to get into alignment with mounting holes, the kit comes with 3 hangers, all of which I did not use or need, the up-sweep of the canister aligned right with the right rear foot peg mounting hole, I did have to get a little longer bolt to finish install, but was 100% well worth the effort, I recorded video of before & after and just love the way new pipe sounds and looks, great product.

Great upgrade for vintage cruisers

June 1, 2011

What a difference!!!! I was totally impressed when I opened the box and saw the headers I purchased to install on a 78 Honda 550 K4 that I'm restoring. I'm stocking it out to replicate one I had 30 years ago, and the first thing I did to it was to put a 4-into-1 on it. The quality and workmanship is most excellent and the fit is perfect which made installing it uneventful. The sound is awesome...the bike is much lighter without the original pipes and the acceleration is noticeably improved... I am totally satisfied with the choice I made to go with the MAC headers and based my decision on the customer reveiws for this item. I have recommended them to my son and his friend who restore honda 750s. I also have a 75 CB 550 K4 bobber that I show and Iam planning to buy another system just like this one for it because the 4-into-1 that is on it at present is vulgar loud and sets off car alarms in the neighborhood. The MAC set will not change the look and will make it sound alot better...A GREAT PRODUCT!!

I would recommend this item to a friend.

EXCELLENT PRODUCT AND SERVICE TOO!

May 30, 2011

I'm currently restoring a recently acquired garage kept 1978 Honda CB550K4to look like one I had 30 years ago..I don't like using used parts and most parters that have factory NOS are either very proud of their stuff or they're very sentimentally attached to it. I came across Dennis Kirk and decided to try them because they stock a bunch of stuff that will fit my old vintage putt. I'm so glad I did! I've bought several items from them from tires to 4-into-1 headers,(my most recent purchase). The headers came at the speed of light...properly packaged to prevent shipping damage...blemish free and just as described...they fit perfectly and the installation was trouble free...all the parts were there and they look and sound great on my bike...dealing with Dennis Kirk is and will continue to be an excellent experience...I recommend them every opportunity I get..Thanks Dennis Kirk for helping to keep the old vintage rice burners on the road.....ph995

Mac 4-1

May 3, 2010

I haven't fired the bike yet, but the 4-1 fits the CB500 like a glove. If it sounds and performs half as good as it looks, I'll be happy

Best Up-Date for my old CB750

February 12, 2010

This has been, value wise, the best up-date I have done to my CB750. The replacement was fast and easy. Some pushing and pulling was used, but overall the fit was good. The new systems look makes the bike look new again. Could not ask for a better product for the price. Thank you Dennis Kirk.
