## Overview

The Flowmaster Original 40 Mandrel-Bent Dual Truck Exhaust Kit features a single 3" inlet and dual 2.5" aluminized steel pipes with mandrel bends for superior flow and durability. Designed for 1988-2018 light- and medium-duty gas trucks (excluding '04-08 Ford), it delivers a rich, throaty muscle-car sound while improving exhaust efficiency. This kit requires professional installation and may need fabrication for a perfect fit.

## Description

Upgrade to performance dual exhaust with a Flowmaster Original 40 Series muffler and give your truck that rich, throaty rumble that you might otherwise expect to hear from a muscle car. The Flowmaster 40 series muffler (430402) contains one large V on the inside, for excellent performance. This muffler will give you that classic Flowmaster sound, with aggressive exterior and interior tone. Our Dual Exhaust kits contain premium 2.5" pipes, with superior-quality mandrel bends that will improve the exhaust flow and may give you the boost in power and fuel economy normally found in much more expensive systems. Our pipes are aluminized to increase lifespan and durability, and are exclusively custom-bent for us in Springfield, MO. These pipes exit under the rear of the truck, parallel with the outside edge of the frame rail. They are designed to clear the OEM-installed receiver hitch and OEM-sized spare tire. The tailpipes are cut into two pieces for shipping, and swedged for easy slip-together assembly. Our system is designed to fit all wheel-base applications, simply trim the tailpipes to fit. This basic kit includes everything from the muffler to the bumper. This kit does not include tips. Fits: 1988-2018 light- and medium-duty gas models of Chevy Silverado, GMC Sierra, Dodge Ram & Ford F-Series EXCEPT '04-08 Ford. Fits only gas applications; fits only applications that came factory with a single inlet muffler! Only the muffler is made by Flowmaster. Please be aware: THIS IS NOT A COMPLETE DIRECT FIT KIT. These systems are to be installed by an experienced, professional installer. FABRICATION MAY BE REQUIRED. Any type of suspension modification/wheel and tire altercation may affect system clearances. We DO NOT provide any portion of the exhaust in front of the muffler. Additional parts & fabrication may be necessary and is to be determined by the installer.

Review: The Bees Kneez! - Bought for my 05 Silverado 1500 4x4 with the 5.3. Everything Fits like a glove! Took me all of an hour and a half to install, which the majority was setting the height of the tail pipes and width, coming out the back. The pipe is VERY good quality! All of the included hardware is 100% American made, and you can tell! It's all very thick materials. The hangers are very well made. The Flowmaster Original 40 is 2 steps down from open headers, and it shows. I know my video is a little muffled, but man is it a throaty exhaust. All I've got done is a cold air intake. Idk if that helps the sound at all. My truck is so responsive now. It's also not overly loud. Sure, if I slam on the gas it's pretty loud, but I'm not that guy. For the money, this is an amazing value!
Review: Great exhaust kit - I put this on a 2015 Chevy Silverado. Its been on there about 6 months now with no issues. Looks good, sounds great. Not too loud.
