FAQ
Will this fit my 2WD truck?
No — S6150PLM is for 4WD only. For 2WD, use the S6148AL.
What’s the difference between PLM and the Street Profile kits?
PLM deletes the muffler for maximum flow and the most aggressive sound. Street Profile kits such as S6150AL and S6150409 include a muffler for a deeper, more controlled tone.
Is stainless steel available for this application?
Yes — choose S6150409 (T409 stainless) for added corrosion resistance.
Does the kit include clamps and hangers?
Yes, it includes the required clamps and uses the factory hanger locations for a bolt-on install.
Can I run this on an extended/Club Cab?
Cab/bed configurations may affect tailpipe section length. If your truck differs from stock wheelbase, contact us and we’ll confirm the right MBRP sections for your setup.
