For 2001 to 2004 Chevy and GMC Duramax diesel engines, the LB7 exhaust parts you’ll find here can make a huge difference in both gas mileage and power output. Installing a new exhaust system into your truck could be just the thing to get that extra edge that makes your truck perfect. We offer LB7 exhaust parts individually for repairs and replacements, but we also offer the entire system. Replacing your entire LB7 Duramax exhaust system can be a large undertaking, but with the right parts from Norcal Diesel Performance, you’ll know that you’re doing the best thing for your truck in the long run.
