Photo of MAC 4 into 1 on bike needed

Posted: Thu Jan 22, 2015 1:45 pm

Anyone have a photo of the MAC 4 into 1 system on the bike? Preferably on an 1100F.

Any experience with quality, fit or installation?

I'm mainly concerned with the down pipes as I plan on slicing and dicing from under the motor - back.

I'll ceramic coat when done so, their finish not important either.

The flanges on the pipe are junk. Go ahead and buy it,it will break and leak. MAC means make another choice.

I love my MAC! Never had an exhaust leak. Tucks nice to the frame on the 1100 900. It is not my first Mac. Please post pictures after you modified.

No pics JR but had a couple. They are a cheap pipe but I didn't have alot of problems with them. Didn't have bikes long enough to grade them long term but never had the flanges go bad. My biggest problem with them was the cans. Ceramic coat would go a long way to making the headpipes a better item. Just seems like a waste to put that much money in one lol. But our choices are getting slim.....

Yea, I know what MAC stands for. I just hoped they had a better product than they make for the CBX.

I'll post in the wanted section.

Much lighter than just about any pipe. Very thin wall tubing.

My MAC Header/collector, fits good, uses the stock half-moon donuts & 750F aluminum flanges, which I want & use.. Has excellent "cornering" clearance, when leaned way over.. I have not scraped the collector when leaned over, while the Vance & Hines would touch so hard to unweight the rear tire. You are wise to make/modify your own mid-pipe & muffler. The stock MAC mid-pipe/muffler is indeed, junk..
