Be-Cut Exhaust Cutout — Open-Exhaust Sound Without Cutting Your Stock Pipe A Be-Cut exhaust cutout gives you the instant, wide-open exhaust roar of a cutout — but with one big difference: it ships with a pre-cut "be-cut" pipe section , so you weld the valve onto that pipe instead of slicing into your factory exhaust. No hacksaw, no measuring twice, no ruined stock pipe. It is the cleaner path to on-demand sound for DIY fabricators and custom builds. What Is a Be-Cut Exhaust Cutout? A standard cutout forces you to cut your own exhaust to drop in the valve. A Be-Cut (or E-Cut) kit solves that: the pipe is already cut and ready , with the electric valve welded to a short be-cut section you simply tack into place. You choose the spot, weld the section in, mount the valve, and run 12V power to the remote switch . The result is the same aggressive, bypass-the-muffler sound — with far less risk to your original exhaust. The Problems a Be-Cut Cutout Solves You don't want to cut your stock pipe. Factory exhaust is expensive to replace; a be-cut section lets you add a cutout and still keep (or restore) the original system later. DIY fabricators hate guesswork. Measuring and cutting a perfect slip joint by hand is error-prone. A pre-cut pipe removes the hardest step. Custom and dual-exhaust builds need flexibility. True-dual systems want both sides opened at once; the remote dual kit does that from one button. You run mixed sizes. Different projects use 2", 2.25", 2.5" or 3" pipe — this collection covers them all so you match the actual diameter. You want sound on demand, not all the time. Closed = factory-quiet cruise; open = track-day roar, controlled from the cab. Choose Your Size & Configuration Be-Cut kits come in 2", 2.25", 2.5" and 3" pipe diameters, each available as a remote single (one pipe) or remote dual (true-dual, both sides) electric cutout. Match the size to your exhaust's outside diameter, and pick single or dual based on your layout. Why Add a Be-Cut Cutout? No stock-pipe surgery — the be-cut section is pre-cut, so you weld, not slice On-demand sound — open for a throaty, wide-open note; close for a quiet street cruise Lower backpressure when open — frees exhaust flow for a sharper, more responsive tone under load Single or dual, your call — one remote controls one pipe or both Stainless build — T304 construction stands up to heat, moisture and road salt Find Your Fitment Confirm your exhaust's outside pipe diameter before ordering — the kits cover 2", 2.25", 2.5" and 3". Single cutouts suit single-exhaust trucks and cars; dual cutouts suit true-dual systems that need both sides opened together. Not sure of your size?
