2Brothers has yet to let me down. Great Slip on set up, deepens the sound without making it obnoxious. Easy install, took about an hour with wrapping the mid pipe. I recommend wrapping the mid, it is much hotter than stock without the wrap. Thanks Bill! -Jon
Not difficult to install. Most likely will require to replace the muffler gasket. Matches well the look of the bike. Sounds well at low to mid range, a little noisy at high RPM.
Exactly as described. Once again, Bill and team have provided a quality, well priced item. They are quick to contact with any possible wrong fit, possible issues, and always have been spot on with solutions or suggestions. Will use Bill's Performance for all my motorcycle needs. Highly recommend this company. (2010 HD Heritage Softail Classic)
I want to highly recommend Bill's Performance for all of your part needs. The entire experience was great. I was having an issue with the FP4 not connecting to my bike. I contacted Bill directly on the phone on Saturday and we were able to resolve the issue with no problems. His response time, patience with me, and customer service are top notch. I will purchase from him again. 10/10 rating. You will not be disappointed. Thank you Bill!!
This is my second exhaust from bill in 6 months for two different bikes he had exceptional customer service and always staying on top of time frame and his prices are better then anyone out there . Overall what makes Bill stand above the rest is his customer service and his passion for bikes that itself tells you what kind of person he is and his enthusiasm for motorcycles.
Bill’s exhaust personally took the time to customize my experience and be sure I got exactly what I was looking for at the best possible price. There was quick & attentive communication for all my needs and I am extremely pleased with my product and service recieved.
Had some fuelling issues in the midrange - tough to find ECUs for bikes of this age these days. Power commander sorted it out, very happy with my purchase and Bill's service.
Bill is a solid guy - will definitely shop here in the future
Had a bit of a miscommunication with the shipping timelines offered on the website as the part had to leave the vendor, arrive at Bill's shop and then be shipped to me. I reached out to Bill and he was quick to do what he could to make it right. My part arrived as quickly as he could make it happen and I appreciated the effort he put in. I'll definitely be shopping here again, fair prices and a good guy to work with.
Amazing product and phenomenal change is performance . I really loved it
