Review on Upgrade Your Ride With AUTOSAVER88'S Black Powder Coated Stainless Steel Exhaust Tip - 4" Inlet, 6" Outlet, And 15" Long Compatible With 4" Outside Diameter Tailpipe by Todd Stepp

I put a flatbed on my 2010 Dodge 3500 with Cummins diesel pickup. This left the stock exhaust pipe discharging exhaust fumes under the bad and tool box. I needed something simple to extend the stock exhaust outside the new flat bed. This exhaust tip fits the 4" OD standard Dodge/Cummins exhaust pipe perfectly. The inner end is 4" ID. Loosen the clamp bolt and slips right on, tighten the clamp bolt with an allen wrench. Good quality product. Fits perfectly. I'll add before and after installation pictures.
