Straight pipes
Hello, I’m new to the site. I just got my first vrod. I love the power but absolutely hate the sound lol. I took the slip on baffle filled stock muffler off and made my own custom chrome slip ones. They are straight pipes and 2.5” x 24” long past the slip on point. I freakn love the way it sounds now. It’s the loudest craziest bike I’ve ever heard.....but @ about half throttle it starts cutting out and popping until you get it at higher RPM’s then it’s a monster. What can I do to fix this. I’ve read several posts saying it’s probably running lean... but there is actually black smoke which makes me believe it’s running rich....either way, it’s not running like it did with stocks. I’ve ready that I need to tune it... idk where to even go to get it tuned. I live in nowhere redneckville Ky. Can I just get a power Commander and take care of the issue?? Or am I still gonna need to take it to dyno shop or something to get it tuned? I don’t wanna pay 800-1000 for a set of stage one pipes and ad-one because I love the sound of my homemade custom pipes. So again, will a power commander fix my problem??
thanks for any help and be safe out there!!!

Other than a dyno-tune, auto-tuners are a great way to go, however, straight pipes are not the ideal set-up for the Revolution engine. A 2-1 will give you much better all around performance, especially on the street.

Straights
Dangit, I was afraid someone was gonna say that lol. I love the sound of the straights I made but I don’t wanna mess up the engine or anything.

2 to 1 pipes
So are any of the 2 to 1 pipes as loud as straight pipes. I’ve had a couple people tell me that they are good for performance but what about the sound? I love really loud pipes. I live in eastern Ky, very curvy, lots of log trucks, coal trucks, crazy drivers, blind spots and loud pipes do save lives. I want as much performance as I can get but I also want the loudest pipes I can get also. One more question. Can my factory components be tuned for high flow pipes, or will I need to invest in fuel management software, power commander, etc?

You really need the proper back pressure and tune. There are several mfgrs of performance pipes that are pretty loud. I firmly believe a 2 into 1 setup produces the best power too. Simply by making your exhaust straight you have detuned your engine and can possibly cause damage to it in the long run.

Yeah the damage to engine in long run is only thing I’m worried about. I heard that strait pipes actually serine the bike but kinda hard to believe because my buddy has a GSXR 750 that outran me with factory set up, then I put straight pipes on, nothing else at all and kept up with him on take off and even outran him on top end in half mile straightaway. Other than cutting out a middle midway it ran like crazy but I just don’t wanna cause engine damage down the road so for now I put factory pipes back on and drilled a few holes in the end to make a little louder.
so again....can factory components be tuned at a shop, or do I have to buy power commander and fuel management stuff to actually timing it..?? I’m gonna go for a 2 into 1 but do I have to buy that extra stuff or can my factory bike be tuned for the 2 into 1??

What do they call straight pipes? Drag Pipes. That's because all they are good for is full throttle racing. That's the reason you out ran your buddy and the reason it runs crappy mid range. I don't know what kind of setup you have on your bike but yes, you do need to change some things. And yes, a shop can help. Engines are just big air pumps. You take air out you need to allow more air in. And for that all to work properly you need the correct stoichiometric values. That's Air to Fuel Ratio or AFR. And to put all that together you need the proper Map. The timing or tuning table. There are those on the market, like The Power Commander, and most are plug n play. You can get very close to what you want without some guy beating the crap out of your bike on a Dyno. Hope that answers some of your questions.

I guess so if that’s what I’ll have to do.... it’s disappointing I can’t use the straight 2.5” pipes I made lol 😂
