Big Radius set the standard for a custom look with quality and perfection in style and performance. Not only do you get a quality exhaust system, you get beautifully curved 2-1/2” full-coverage heat shields, end-tips, and blue-proof show quality chrome. Vance and Hines didn’t stop at style and quality, the Big Radius produces extra horsepower and torque delivered with a signature hotrod sound that leaves you begging for more. The Big Radius exhaust is perfection in style, performance, quality and sound. Vance & Hines has designed a flat plane mounting panel for the 12mm oxygen sensors now employed across the Dyna model line, which positions the sensor deeper into the exhaust stream, providing enhanced data feedback to the ECM.
Full coverage heat shields
Signature chrome badge and end treatment for a sleek contrast style
Welded-in ports for factory 12mm O2 oxygen sensors
Louvered core baffles and mounting hardware included

Jason V:After taking to a Harley dealer just a few days ago, the answer as I understand it, is yes. They told me I had to buy that for them to Dyno tune my bike. Even though I had another brand off tuner. So, if you plan to have as dunno tuner done, I'd recommend taking to the tuner/mechanic who will be doing the work.Jun 20, 2015
A shopper asked:Are the big radius 2 into 2 higher than the standard pipes on wide glide 2014 ? Unhappy with how easy the standard pipes scrape and want a higher alternative and like the big radius v&h lookSep 17, 2014
Daniel M:They do allow you to lean more to the right. However the tips will still hit sooner than you'd like. That being said. I wouldn't trade them for any other pipe! They look and sound amazing on a Wide Glide.Sep 22, 2014
yazici h:yes big radius 2 into 2 pipes are a bit higher than origanal wide glide pipes . that pipes sound is perfect and you will feel horsepower gain in low range rpm .I hope you will be love itSep 20, 2014
Maria B:Yes I live in ventura county, I have been pulled over for speeding a few times and they never once mention anything about my exhaust. They actually told me how good my harley looked and how good it sounded. Remember there is no smog checks for motorcycles. Feb 3, 2015
