Aftermarket exhaust

[Wadejesu]

I was thinking on getting rid of the smaler visible pipes inside the exhaust tips, using only the bigger ones would create a bigger rumble and create a meaner look while keeping it original until you look closer, I will probably start in 2 weeks as the bike is my daily ride to work

That's what I was thinking, Let me know how that works out.

If you do, video and a sound clip, pls.

Lot's of projects in the works. I just checked this one off the list.

Perfect, looks like it holds 6 beers, a couple shot glasses with a few holes for misc.

This is the pipe I'll be playing with. Just need to decide what I'm going to do for a finish. This is polished 304 stainless

This engine is 2.5 litres. A simple small volume slip on may be noisier but it will reduce power not increase it. I have cut the cat box and left can off mine and opened up the two outlets to 2.5 inch, it sounds good but even remapping with a Powercommander Five I can only equal the original power. The biggest restriction is the 44mm outlet of the headers, I will be increasing this to 2 inch to help reduced the back pressure . But as much as I love the looks of the stock exhaust and it will take a lot to beat I fear I will end up making big bore headers as well to get any NA power increase.

Here is a link to my Facebook with a video of the new exhaust note.

This past weekend I decided to pull my exhaust. Unfortunately I took no pictures...... but I cut open the big black box to look around. I found a maze of tubes . I wanted some more bite to my exhaust. I did not want to pull whole thing apart at the moment. (Warranty) I ended cutting out the cat inside the box to eliminate half of the maze of tubing and some restrictions. It ended up sounding better(could be more) but I definitely am happy I did so. I also noticed right away more seat of the pants power! Once I cut it out I welded piece back in smoothed it out and repainted it. You can't even tell i was in there!

Here is a very crude drawing of the exhaust system layout. Green being pipes and red exhaust flow.

Did you leave the pea shooter exit pipes? I cut mine out to the diameter of the big pipe, about 63mm. You can hear the bark on my video, its pretty acceptable still, not to loud while riding. I had to do a lot of fuel remapping and ignition changes to get the best out of it.

I did not yet. I was seeing what happens with the changes while still appearing stock. I was really excited about the competition werkes exhaust but the 1k+ price tag in my opinion is expensive. Considering also all their other slip on's are $549. I can only assume the price reflects the fact that there is no competition.

The lines of the stock exhaust will take some beating. The CW one doesn't do anything for me.

Richard: Would you consider a pipe from the headers leading to a chamber, kinda like a wee car silencer with three outlets into these (pictured below) doable or an excercise in futility?
EDIT: I don't really care if it doesn't add power. My main concern is looks weight and sound (and of course i wouldn't want it to *lose* power..
