Product Description
DIAMOND EYE 510204 is a 27" aluminized-steel muffler delete (4" I.D. x 4" I.D.) designed to replace a 4" universal muffler section and restore maximum flow. Heavy-gauge construction and straight-through geometry make it a go-to choice for diesel trucks running 4" systems.
FAQ: WILL THIS FIT MY EXHAUST?
Yes—if you have a 4" aftermarket exhaust system (Cummins, Duramax, Power Stroke, etc.) and enough straight length for a 27" section, this pipe is an in-line replacement for the muffler. It uses 4" I.D. (slip fit) ends on both sides to match standard 4" tubing.
FAQ: IS IT LOUDER THAN A MUFFLER?
Generally yes. Removing the muffler increases volume and turbo whistle. If you want to reduce drone or keep sound modest, consider a Diamond Eye performance muffler instead (see Cross-Reference below).
FAQ: ALUMINIZED VS. STAINLESS?
Aluminized steel offers excellent value and corrosion resistance for most climates. For harsher environments or salt exposure, consider the stainless 27" alternative listed below.
