FAQs
Will this fit my 2004 (early-2004) truck?
This kit is for 2004.5–2007 model years with the Common Rail 5.9L (Cummins 600/610). Early-2004 (03–04) trucks use different part numbers.
Is this a full turbo-back system?
No. It’s a cat-back system that connects behind the factory catalytic converter.
Does it include a tip?
MBRP offers variants with and without tips. If you specifically want a “no tip” version, see the S61180P. Tip availability may vary by kit; check the product options on each listing.
How loud is it compared to stock?
Expect a deeper, more pronounced tone with lower EGTs from improved flow. For maximum volume, consider the S61180PLM (no muffler).
What comes in the box?
Cat-back tubing, muffler (where applicable), hangers, clamps, and installation hardware—engineered for a bolt-on install using factory locations.
