Q: Can I install this without removing the intake manifold?A: The intake manifold stays in place. This kit is designed to work while retaining your factory intake and exhaust manifolds. Q: Is this compatible with a DPF delete?A: Yes, this kit works perfectly alongside a DPF/CAT delete pipe. In fact, many customers install both as a complete emissions delete package. Q: How long does installation take?A: Approximately 2–3 hours for a professional mechanic. DIY installers should budget 3–5 hours depending on experience.
