Bike looks much better without the old muffler box BUT I did not anticipate how loud my bike would be with a full straight pipe. I have an Acropovic Megaphone exhaust tip without the db reducer on and stock headers. It's way louder than I wanted. I tossed the db reducer years back and now I'm looking to buy the reducer seperately...

This a really nice looking box. I had one on a honda reflex 250 so when I bought a new suzuki burgman 400 I knew what i was getting. I had to drill some extra holes in the mounting plate that didn't line up with holes in frame, but the bolts that came with the box were the right size. I put some one  inch spacers which worked out perfect. Didn't hook up the lights but wouldn't have been a big deal. I like the size, looks, and it is a sturdy box.

Looks much more stealthy than the deore bb that came on my bike

...and that's what I got.  I keep pretty good records so the fuel economy would have shown up.  Of course, I probably have my foot in it more now since it is pleasantly louder than the stock setup.  It's not offensive and my wife wouldn't have noticed it if I didn't mention it to her.  It really cleaned up the engine bay to get that giant box out of there.

I like it sounds good they need to make a spacer that goes on the head before the exhaust goes in so you get more clearance from bottom of exhaust to frame would make installation so much eisier

This cai looks far better then the factory and adds quite the rumble to my x piped exhaust as well as opens up extra response on the top end of the rpm spectrum. The tone under the hood took a drastic change for the best. Overall it improved the sound, response and breathing of the engine.
Update:
On the factory tune it never had any issues but it's basicaly a must have if you get a programmer and start doing other N/A mods. It sounds mean on the factory tune but really screams once it has a race tune setup.

The mufflers are a five star. Well made.  However, I used them on a 1978 Honda  CM185 and  the provided reducers did not clamp down on the header pipes. The slots in the reducers appeared to be to narrow. I was not happy at all!  I ended up going to Auto Zone and buying a reducer that would slip into the tail pipe and another one that would fit into the previously mentioned reducer. Then I inserted the smallest reducer into them, Took that contraption to a local muffler shop to be welded. Now the mufflers can slip on and be clamped. What a Pain in the @$$. The sound is awsome on this little bike. Nice deep throaty sound.

I really like the tank but, it took a lot of work fitting it to my 09 650l mostly due to the two front bars that support it. My end result was eliminating the front mounting hardware in favor of aircraft cable and a pair of exhaust springs that seam to work very well. If the tunnel had been even an 1/8in wider I would have no complaints. I used a 1-1/2" riser on my handlebars to eliminate the interference with the tank. all in all it functions very well and it looks good on the bike as well

After extensive research on blogs, forums, and websites, I found the V & H pipes to look the best for my Screaming Eagle V-Rod. I was nervous about the sound, if they weren't going to be a sufficient upgrade in volume. I was extremely happy with the noise level - not too quiet, not to obnoxious - just right. They installed in a couple of hours and adds another element to the look and feel of the bike. Installed a fuel commander and K & N high flow air filter - will have the bike dyno tuned in spring.

Fit my ux303ub just right! Looks much better now

This fit my 2017 RC390 perfectly!  Watched their video then took my time on the install.  It was no big deal and I love how it improved the look of the bike.

Very pleased with the sound, baffles removed easily. As for looks, I was hoping they put the logo that is pictured but rather it came with a red sticker tape that says silmotor and matches my bike better anyways. The end caps are clear coat carbon pieces and beyond that it looks like a clear tape of some sort that is wrapped around many times, maybe you can see the texture close up in the picture. I'm guessing it's a functional heat reducing material. Other that that the pattern of the carbon is gorgeous. Mucy lighter than stock exhaust. The mounting bracket is super clean, the install was easy. They look stellar on my '13 Ducati Streetfighter 848! Also good to note that there was a little but of a noticeable power gain, I bet gas mileage might be a tiny better due to slightly lower cruising rpm on the freeway. I definitely recommend getting this, you won't regret it.

This muffler did way more than I thought it would. It is a baffled flow through design. I have been running a straight piped 4" exhaust on my 24v 5.9 Cummins Diesel. My exhaust is short and exits in front of the rear wheel under the passenger door. It used to be unbearably loud,  even at idle. With this new muffler it is now very quiet at idle and the rest of the range is deep and muffled. You can still tell it sounds like an aftermarket exhaust and it does still get loud if I get on it, but it doesn't have those harsh raspy tones anymore and it is way more muffled. Massive improvement for just slipping a muffler into the place of my blank test pipe.

I removed my saddle bags to give my Suzuki Boulevard a clean look.  This small fork bag looks great and gave my bike a clean look!  I don't do any traveling, so this fit the bill.

I fixed the bike all ready and didn't need it. I put it all on just because I didn't want to feel like I wasted money and oh my!!! I was missing something in my other set up. FINALY THE BIKE RUNS LIKE ITS SUPPOSED TO!!! the best money I have spent on a bike in years. just plug and play. no tuning. I am a guy who wants to tune but I couldn't. it ran too good right out of the box.

Installed on my girlfriend's 2009 (2010) model after the header pipe on her stock one cracked. This is way lighter, feels better, and is much louder than stock -- it has a nice sporty sound to it, and sounds like a real bike now. (It is louder than my Shadow now, which I figure is good so that she will be noticed by other motorists.)

Docked a star because of how hard it was to actually put the pieces together -- particularly mating the muffler to the header pipe. You WILL need some WD-40 or similar lubricant, and you WILL probably bust a knuckle or two.

Be sure to buy a new exhaust gasket: I used&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/James-Gasket-Exhaust-Port-Gasket-Kit-JGI-17048-98/dp/B00AC5ETY6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">James Gasket Exhaust Port Gasket Kit JGI-17048-98</a>. The old one will probably be pretty well and smooshed into the exhaust port.

Fit good, not a fan of K&N products but I needed a filter and this was less time involved than going out to the nearest Yamaha shop. This looked exactly as the one removed from the bike, a mesh brass or copper media so I do not know if the stock one is like this or the one I took out was another K&N
