I’m interested in turning my stock head pipe into a 2-1. I know it’s been done, Khrome Werks had a kit but is difficult to find and honestly the slash cut muffler looks cheap to
me. Anyways I’m a welder by trade and I was going to de-cat, cut off the crossover nub flush and tig weld it so flow isn’t disrupted. BUT I’m having a difficult time finding a decent muffler. I haven’t found any slip-ons where purchase of just the RH muffler can be bought. Ghost pipes can be bought, why not just the a RH replacement muffler. Has anyone come across any? FM RTX, MK45, HP+, etc. right side replacement is all I’d need.

 

There's nothing cheap about Khromewerks and their performance is top notch too. Their HP Plus has a proven track record here and they've been around for decades.
I'd put money on them being better than any of those you listed except HP+ which IS Khromewerks. In quality, sound, and performance.
Their 212 systems will outperform most 2in1s out there. I don't know about purchasing just one muffler. Not sure why anyone would want to but that's your business.

 

Fairly certain anyone who scuffed or dented one muffler would like this option

 

Or anyone doing a 2-1 exhaust system which only has one muffler 😉

 

I never implied Khrome Werks being a cheap or poor performing brand/exhaust systems. They’re top 5 I’d say for sure. BUT what I was referring to is the Khrome Werks Torque Booster conversion kit, google it, the muffler included with the kit if you can find one still available doesn’t look as good of quality as their other products. The slash cut 1-piece black muffler body is the only ones I can still find available, maybe they discontinued it? Maybe there was a reason? But the idea still remains…

 

Good point. I don't know many that will sell just one tho. I suggest calling them. They're owned by another parent company now. I forget the name. 5 years ago I dealt with them on the phone looking for a discontinued size of their AR "dogballs" baffle. They went out of their way and searched their warehouse and found a set they sold me dirt cheap. Can't hurt to ask.

Given the airflow characteristics of our engines, if you really want the best performance, I'm sure that companies have figured out how to put out a product that maximizes performance in the right size and shape package. I'm sure anyone with a chop saw and a mig welder could make themselves a pipe, and there are tons of universal baffles on Amazon and Aliexpress to make yourself a muffler. But I'm not sure it'd perform on a dyno like the pipes that are out there.

 

Is this based on pics or actually seeing it? Just curious. I know the quality and the way they make their mufflers can't be beat. Just handling one you can tell they are well made and they're ceramic coated inside and out. I've never seen a better made muffler tbh. I had a set of their HP Plus on my sporty and I bought a set for my current softail before going with the bassani pro street true duals and returned them. I can say the quality is night and day in favor of the khromewerks but I also have my original Rush cans which are also top performers.
I'm just surprised if they manufactured this particular muffler any different is all. Not saying it's not possible.

 

Universal baffles are a dime a dozen. Ones that perform well are not. The ones that have been around for decades are for a reason. They work and they work well.
Very few manufacturers spend the time and R&D money on providing a well performing exhaust. Too many people buy based on looks and sound only. So why should they?
I would say at least 80% of exhaust systems out there are trash when it comes to performance. Something that becomes apparent when used with performance cams. Reversion is a very real and power killing thing when exhaust and cams don't play well together.
Way more important than whether it's a 2in1 or a 212.
True duals are another story altogether. I can only think of two that work well as far as twin cams anyway. When you lose the scavenging effect of a 2in1 and 212, stepped pipes are necessary I think. Just my opinion from what I've seen over the years.
I think 44" is the optimal length as I recall too.

I talked to Khrome Werks and they said they don’t offer the conversion kit anymore but they’d sell a single muffler no problem. So if a person was proficient enough at welding/fabricated it’s definitely possible to do what I mentioned for a “home-built” 2-1 with a quality muffler. We all know the stock head-pipe on M8’s once de-catted are one of the best to use. I haven’t seen charts of people using it for a 2-1, but the 2-1-2 with quality mufflers has proven and I can’t see it being worse. Now just choosing a muffler with sll
the options….
