FLOPRO EGR Delete KIT

Factory cooler setups recirculate soot and harmful gasses through your engine causing build-up and clogs, resulting in loss of performance and proven mechanical issues. GDP Cooler Upgrade Kits remove those concerns from the equation. GDP components install with an exact fit resulting in a longer lasting & better running truck, less turbo lag for better throttle response, cooler engine temps, less weight and a cleaner looking engine bay. Proudly Made in the USA.


DPF Delete Full 4 Inch Exhaust System.
The Delete Exhaust is a full 4 inch exhaust system from down pipe back entirely replacing your old exhaust systems and deleting all emissions components, meant to work in conjunction with the Delete Tuning.

We send either FloPro OR MBRP (P1) Race Exhaust systems depending on what is available at time of order. Both Exhaust descriptions below.

P1 Race Parts provides you with enhanced performance, styling, sound, and airflow. Made from only the highest quality materials, P1 Race Parts is the premier choice for the at-home diesel and gas enthusiast, competitive drag racer, or sled puller. Whether you’re taking your purpose-built sled pulling truck down the track, or tearing down the quarter mile, P1 Race Parts has you covered. P1 Race Parts are specially built for an easy installation on your GM Duramax, Dodge RAM Cummins, Nissan Cummins, and Ford Powerstroke, Sport Compact and Muscle Car. Constructed from your choice of T409 stainless steel, T304 stainless steel, or aluminized steel, P1 Race Parts offers an option for every budget and a material to withstand every type of environment.

Improving the performance and sound of the 2017-2019 GM Duramax L5p is as simple as installing one of P1’s Race Parts, full Race Exhaust systems or Race Component Kits. These Race kits feature mandrel-bent construction and work with factory exhaust systems.

	We make our exhaust systems stronger where they need to be the strongest with machined turbo flanges. Most of our modern Dodge systems come with a machined flange that matches perfectly to your stock or aftermarket turbo. The alternative construction of a turbo flange is to over expand the pipe and flare it out. We used to do that, but that process created a weak spot in the 16ga steel and often had to replace downpipes for damages caused by stress and vibrations off the turbo. If you order a FLO~PRO kit, your turbo clamp will thank you!
Why would you buy a system that only has 1" of weld holding the hangers on? Your truck works as hard as you do and hangers take a beating. We machine all our exhaust hangers to contour to the shape of the pipe. This allows us to apply a longer bead of weld to the hanger to greatly reduce hanger failure. Where there was once one inch (1") of weld before, now we have 6-7" of weld on our hangers. Using alternative hanger clamps causes unnecessary stress and added time to installing your kit. The clamps don't typically have a whole lot of surface area to weld, so we try and avoid using them as much as possible.
	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, we include 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.
