The HSP 2" Replacement Up-Pipes are an excellent high flow upgrade to replace the restrictive factory pipes on your 2001-2016 GM 6.6L Duramax. The 2" design not only increases flow and power, but also reduces EGT's! Heavy wall 304 stainless steel construction coupled with heavy duty sleeved bellows means these pipes can handle anything you can throw at them.
