Reviews for Vance & Hines Black Big Radius 2-into-1 Exhaust System - 48003
I teamed this exhaust with the V02 intake and the V&H Fuekpak. So far loving the sound and performance. Originally installed without the baffles as i was looking for alot of sound. I quickly realized that it was too loud! Reinstalled the baffles and reset the Fuelpak accordingly. Sounds great now!! Only gave 4 stars on the fitment as the heat shield did not line up quite as neatly as expected even after multiple readjustments.I would recommend this item to a friend.
Rear cover welds break
I have a 2011 Fat Bob and purhased this pipe at 1000 mi. Rear cover clamp welds broke and the pipe cracked after 1200 more mi. Vance & Hines were very quick to send a new cover no charge. It lasted about 4 weeks before I had the same problem with the welds no crack in pipe. At the same time I purchased the V02 air cleaner with theDrak cover which the welds have failed on the Drak cover. Very dissappointed. I do ride daily and the air cleaner cover made it to 5000 mi. and out of V&H warrenty of 3months. One last note Pipes make it hard to check oil hot you wil need gloves.I wouldn't recommend this item to a friend.
FXDF Big Radius 2:1 Exhaust
Vance & Hines made an excellent product with the Big Radius 2:1 exhaust system for HD Fatbob. Fit is excellent; nothing heavy to wield around and the piece matched cylinder heads with little effort. Finish was a little on the fragile side (my opinion) and scratched easier than I like when installing heat shield clamps. Installation was about an hour and a half, but I tend to obcess at attempting to achieve factory look. HINT: hardest part was attempting to install shield clamps by myself... a second set of hands to help start bands will save lots of time. Performance is very good; (with new map, and Stage 1 air filter) engine seems smoother, and very quick on acceleration. Exhaust is about 30% louder than stock SE 'double barrel' setup and also 25 lbs lighter. Cosmetics are superb with hot performance.I would recommend this item to a friend.

V&H 2-1 Big Radius "Black Finish"
I ordered the "black finish" Big Radius 2-1 from Denniskirk it arrived within a week. I removed the old and installed the new V&H exhaust on my 2010 Harley Fat Bob everything fit perfect and lined up easy I would say a 2.5 hour job alone. Like every one else stated the black finish is pretty soft at first it seems to get tougher after you run the bike some and the exhaust gets hot a few times. I gave the finish a 4 star becuase that is about the only thing I think V&H could do better on. Other than that the exhaust sounds great,looks great,fits great, and I love the deep tone it has sound is very mean. I have had several people ask me what upgrades I did to the engine just because the exhaust sounds like the bike is on steriods not your everyday loud high pitch poping exhaust sound. Be warned this is not a quiet exhaust if that is your goal. I didn't expect this exhaust to be this loud after reading some reviews I was expecting something medium loudness with alttle deeper tone. I would say at idel its medium but when you trottle the bike it jumps up there to medium/high not crazy loud like short shots big radius 2-2 but you can hear it and the family next door will hear you take off 100% for sure. Overall I am very pleased with the sound and look of this system it was alittle louder than I expect at first. I was looking at buying a quiet baffle but after driving now for a couple of weeks it sounds perfect to me so I am not changing a thing.I would recommend this item to a friend.
These pipes are absolutely perfect in every way, the fitment was perfect on my 2010 Fatboy Lo, looks awsome and IMO has a really good balance of sound, not super loud but just right. These pipes combined with the ventilator intake and SE race tuner gave a good incresae in preformance. Like the previous review stated the finish is easily scratched, other than that there perfect.I would recommend this item to a friend.
Great looking and sounding pipes.
I received my order in 3 days, so kudos to DK. When I opened the box one of the heat shields finish had been beaten off. It didn't happen during shipping (the box was perfect), so it must've come from V&H that way. DK promptly sent me a new one, along with a prepaid return label. It sounds great, not drag pipe loud (thankfully). It does produce a bit of a whistle sound, but it can only be heard while sitting on the bike. You couldn't ask for a better looking pipes on a Fat Bob. I did have to pull up on the end of the pipes to get the bolts lined up in the support bracket. These same 2 bolts became a little loose after a few hundred miles, even with loc-tite. You can't go wrong with this system.I would recommend this item to a friend.
Vance & Hines Stands by their product
I put these pipes on my 2009 Dyna Fat Bob...Pipes sound great and give the bike a Awesome look. I had trouble with the weld on the heat shield 6 months after I bought the pipes. Vance & Hines took care of the problem and sent me a new heat shield free of charge. I'll always have Vance & Hines on my Hog.I would recommend this item to a friend.
