FAQ

No. This pipe is for an HX40 outlet. For stock turbos you’ll need the appropriate downpipe or an HX40 outlet conversion.

Yes, an HX40 V-band clamp is included. V-bands are metal-to-metal joints, so no gasket is used. Keep flanges clean and aligned.

This is a 4" downpipe designed to integrate with typical 4" turbo-back systems for the 2nd-Gen Ram.
