Halfway through 2015, GMC made a production change in the connection between the catalytic converter and the turbo direct pipe on the LML. Please ensure you have the late LML 3-bolt style flange before ordering this kit.
Founded in 1981, FLO~PRO Performance Exhaust has been manufacturing and distributing only the most durable quality muffler and exhaust systems for your vehicle. FLO~PRO has proven it beats the competition with louvered pipe that accelerates the exhaust flow through our mufflers. FLO~PRO performance mufflers are designed to boost the horsepower generated from your street vehicle. The 100% aluminized steel welded construction will outlast conventional locked-seam, double wrap mufflers. The louvers also give a deep performance sound without the use of fiberglass that would eventually blow out! FLO-PRO also specializes in Diesel Performance carrying full systems for virtually every diesel truck.
Exhaust pipes were made round, they should stay that way! FLO~PRO includes lapjoint style clamps in every kit we sell. Lapjoint clamps keep the pipe round and have two (2) independent bolts that need to be torqued to 50lbft for an everlasting hold. Since the exhaust is not being damaged by saddle clamps or u-bolt clamps, modifications down the road are made simple. If your pipe has been damaged by a saddle clamp, you could end up having to replace your entire exhaust system.
Another bonus is that if you order a stainless exhaust system, FLO-PRO includes stainless clamps. Sure, aluminized clamps are cheaper and do the same thing, but you ordered a stainless exhaust! Everything is stainless from the flange, clamps, hanger and even the weld.
