"Patina" The 1973 CB175 Cafe Racer

I didn't cut mine... The CL has a different 'modern' contour to the front fender, which I enjoy.
 
Maybe you guys can help me decide on my exhaust. I would really love to have high pipes on ole girl but I'm not about to pay the price some are asking. I have seen some CL175 pipes (total system with muffler and brackets) on eBay for 250 shipping included. They looked to be in great condition.

My other option is to buy about 100 bucks worth of steel tubing and bends, a DCC shorty 1-1/2" muffler and pay the guy up the road $120 in labor to weld me up a custom 2-1. That totals up to about $340 once I include shipping from DCC.

From a performance and exhaust note perspective, what would you guys think? I know this is heresy but I would probably run the stock CL exhaust for a while and the chop them off and weld in a collector to a 2-1 high pipe of sorts.

Sell the cl pipes to pay for the new exhaust. If you're saving for an ignition you may have time to save for the exhaust also.

Clem, you're saying to buy the CL pipes, run them and save for a new exhaust then sell them when the new exhaust is built?

I thought that you had the cl pipes already. I always go back and forth with buying a set for my cb160. I have a soft spot for them.

Yeah even as stock they are quite the good looking addition. Your comment made me think. I'm going to go the route I described above and buy the stock set for now. Then have the other set built and sell the original.

To make my 2-1, I bought three of these and some alignment sleeves once they were cut up correctly.
No all of the bends were perfect transitions. Some slightly tapered straight cuts were used after fitting the head pipes.

I also made some new bolt down flanges that welded onto the pipe.

If you go the fabrication route....

Gah that thing is nuts!! ACM, the stock OD of the headers for mine are 1-3/8. How did you fit up 1-1/2 stuff on yours? Also did you make the collector out of the 180 bends or buy it?

FYI I saw these on eBay and thought they could be used somehow...

Also is the outlet the same size as the inlets? It's looks a little smaller...

She's looking good. The clip-ons are correct. Play with their position up and down once you have the pegs on and you ride it. Obviously the angle can be changed so they don't look like drag bars. Thanks for allowing me to help on your project.
The pipes in the pic look nice but it would concern me that they are blocking so much of the cooling fins of the cylinders with them in such close proximity, all they will get is hot exhaust air blowing through there.

No, Thank you!

I've gotten some PM's around the powder coating you did. Hope you get some traffic from it.

why so big with the head pipes ? me thinks you will lose power a precious thing on a tiddler like that

Yeah-- I agree. 1 1/2 is bigger, but it does fit... At the time I bought the smallest available from the catalog. When I do them over, id change to 1 1/4 in tubing for the headpipes.

The collector shown in the photo was purchased online (I forget where). The outlet is a slip fit reducer that works with the 1 1/2in tube.
I ended up scrapping that collector and making my own collector due to fitment issues.

So the 1-1/2 fits inside of the cylinder head holes alright? Is it a tight fit?

No jamming required.

These are also 1 1/2in 1-1 pipes I used initially.

Yeah I do... But id like to keep them. (If that was your next question)

I should make some production runs or publish some 'popular mechanics' style instructions... :)
 
Dude seriously. All I need are the headers. I have 2 emgo shortys that could be used easily. In all seriousness, I'd be happy to Paypal you some cash as soon as you say "go".... If I come across desperate, it's because I am :)

If it weren't winter I'd make you a set. It would take me some time to pick the days with better weather. I have a heater, but I don't like to weld with the garage door closed.

Stick with it, hopefully you can find someone with the skills to give the materials to.
