PRXB exhaust brake offers the highest braking power to lowest price ratio available. Pacbrake's flagship product is the unquestioned leader in the supplemental brake industry. It has changed the way people think about exhaust brakes by providing performance, safety and durability that is unmatched by any other exhaust brake on the market.Product 1. Provides 50percent More Braking Power at Lower RPM's PRXB gives you the BEST holdback in the 1400-1800 RPM range (where you typically drive). Better than any standard exhaust brake on the market. 2. The spring controlled pressure regulated mechanism on the exhaust brakes protects against engine overpressure. 3. Pacbrake exhaust brakes are designed specifically for individual engine applications to maximize performance and reliability. They are not a one size fits all compromise.4. When the brake is deactivated, exhaust flow is unrestricted and won't interfere with power output 5. Patented 90 degree Non-contacting Butterfly Valve is specially engineered to maximise backpressure while preventing seizing. 6. The brakes use industry exclusive Arcor nitride coating on housing and components which increases resistance to wear and corrosion while strengthening the exhaust brake and adding lubricity.7. Precision machined surfaces on the exhaust brake eliminate the need for troublesome gaskets and risk of leakage.8. The brakes have hard anodized aluminum and stainless steel body and shaft with high performance seals. 9.Maintenance is as simple as using the exhaust brake on a regular basis and periodically applying Superlube (Pacbrake's multi-purpose heat resistant lubricant which helps to prevent rust and corrosion).Every PRXB Automotive Kit comes with everything required for a complete installation. PRXB Exhaust Brake, Controller (when required for application) and Pacbrake Onboard Air Kit, which includes: HP325 Series Compressor, 0.5 Gal Air Tank, 25ft Coiled Air Hose, Air Accessories and Fittings Kit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.
