Traditional Scrambler Exhaust

Mac Performance sells an exhaust system for the Bolt that has the characteristics of a traditional scrambler exhaust. I put it on my bike and it looks great. Once I have my new baffles and intake installed along with a flashed ECU, I plan to get a custom fuel map made for my setup. All of this will be done during the next couple months and I will post pictures and a sound clip then if I'm able.

Ha. Interesting. How/where is it supported? Presumably somewhere near the battery box?

You remove the passenger foot peg and replace its mount with the one supplied by Mac. So yes, your assumption is correct.
Looks good - been thinking about different exhaust setups that allow for peg relocation (moved up, back and tucked in), and this is one of the solutions I've seen before. Thanks for posting up a pic with your bike!
It would look better with a pair of reverse cone mufflers on it, honestly. Looks like that'd be an easy thing to do too - just cut the pipe off after the last bend and bolt them right on, spreading the pipes a little. Or weld a little angled adapter onto one of the pipes so they don't have to spread apart. Either way, it'd be a great look!

Where did you get the pipe and how much was it?

That would look great. But I got them for $500 from Mac Performance, so there is no way I'm cutting these. To be honest, I'd prefer to make my entire exhaust system from scratch, but I don't have the necessary equipment at the moment to make that happen. This was my second and only other option, as the traditional look is what I'm going after.
I purchased the baffles that were also made and recommended by MAC Performance and during the install a few small chips of the chrome came off of the exhaust. So I may just hack these up the first chance I get now. Pretty disappointed to say the least.
What's the OD of the pipes? If it's 1.75" or less, you could run a pair of EMGO upswept megaphones like these:



If you got a left and a right one, they'd mount directly to the pipes and angle away from each other properly. You'd just have to cut your headers short with a hacksaw, and any damage on the end of the header will be hidden when you clamp the mufflers on.

Here's what the other side of the muffler looks like:



They're about $65ea on eBay.

MAC Performance contacted me and they're willing to replace the exhaust pipes. @ChopperCharles, I may still order those mufflers next month to see how well they will match up to the existing bends of the pipe. I do really like the look you're thinking of.

could you measure from the top of the top pipe to your shock cannister for me ??? talked to JR @ mac going to have him make me a stainless one with angle cuts at the shock cannister
thanks
Change that, sorry. From the end of the top pipe forward to the shock
Canister.
Already Returned

I sent the exhaust back out to MAC already. Take a look at the image I attached to this reply. There is a bend in the exhaust right at the shock's location. I wasn't expecting that when I originally ordered them so it was a bit of a surprise. The pictures on their website make it look as if it is perfectly straight, but it isn't. You'll only notice the bend if you already know it is there. That could be problematic if you were planning on installing baffles. But you could always cut the pipe up near the side number plate, slide in the baffles, and weld it back up.

I still have not received a replacement from MAC Performance or any confirmation that one is on the way. I feel like I’m at the stage of pulling teeth.
Yikes. I was thinking about replacing my Two Bros Comp S system with the Mac exhaust, but now having second thoughts. Sorry you had to be the guinea pig!
Are you not happy with the 2 Bros exhaust? I'm interested in your opinion knowing that you've had it long enough to know.
IF, I say if, I was to buy an aftermarket exhaust it was going to be 2 Bros with the black finish.
No no - I'm totally stoked with the quality, aesthetics, tone, and performance of the 2 Bros Comp S system, but I have a vision of fabricating slightly higher and more in-board foot control brackets for my SCR to improve clearance. Doing so requires the re-routing of the exhaust either above or further below the current "stock" position.

Here's an example of how a custom builder did it:

That’s a nice looking system. The headers aren’t by Arrow, then?

****! That is one sexy looking exhaust! I would give that one a go, if it doesn't break the bank.

I spoke too soon. I found an Arrow slip on for the clearance price of
$707! That's JUST for the slip on!
The more I shop, the more I want to leave it stock!
