Our custom stacks are Engineered to flow more air and give you the looks, and performance gains you desire.
Although there are several competitors offering cheaper and inferior alternatives, SoFlo Diesel's quality and attention to our products far surpasses the competition.
We strive to give Diesel Enthusiasts the most soild, best looking, and highest quality stacks available.
We use thicker material than our competitors, which yeilds less drone, more soild mounting, and lower stack temperatures to keep your load safe.
We love what we do, not to mention our stack kits are hand welded, cut and coated in the U.S.A
Our Stack features
- Our Simple Single kits use an effective and clean plate design, that allows for no inlet reducers, no clamps, and a full 8" stack from bed to tip.
- This allows for awesome looks, great flow, great sound, and super solid and easy bed mounting.
- Each kit is designed to fit as many configurations of trucks as possible. which means that the kits are universal, allowing for easy installation whether you have a Dodge, Chevy, of Ford, long bed or short bed.
- All stacks are powdercoated, using a slightly modified process, to withstand the heat, and retain a like-new finish for years to come.
- The Standard 40" total height puts the top of our stacks right in between top of rear window glass and below the roof line on most trucks.
- Note, When selecting the perfect height for your rig, our Stacks are measured in total height, from bottom of the bed to the tip of the stacks.
- Easy, bolt-on design, makes the Stack installation process as friendly as possible. The things such as bolt on installation make the difference between a fun time, and a nightmare.
- All stacks include all needed hardware for mounting stack to the bed
- Optional Inlet Kits are needed if installing Our stacks to your exsisting exhaust system
Most stacks are built to order, hand welded using TIG and MIG processes.
Normal Ship time is 5-7 business days, depending on sizes and color
