Upgrade your exhaust on your 1st Gen Cummins 4x4 with this 4" turbo back 409 stainless steel system from Diamond Eye. The factory exhaust on your Cummins is highly restrictive and installing this kit will gain you extra horsepower, lower EGT's and an overall better sound.

DETAILS OF EACH MUFFLER/ELIMINATOR PIPE OPTION

Diamond Eye Muffler: This is the standard muffler that comes in the kits. Featuring a stainless steel construction and perforated core, you really can't go wrong with this muffler. The muffler itself gives the truck a deep tone, while not being overly loud and does a good job of reducing exhaust drone.

No Muffler / Straight Pipe: For those that want the uninhibited sound of straight pipe, here it is. This is a complete kit, but instead of shipping with a muffler, you will receive an eliminator pipe to give you the exhaust bark you're after. If you ever want to put a muffler back into the system, you'll merely need to remove the eliminator pipe and install a proper length muffler.

EXHAUST TIP OPTION

No, it won't add 20 horsepower or give you better mileage, but adding an exhaust tip simply adds the finishing touch. As another way to make ordering easier, we allow you to simply add Diamond Eye's most popular tips right from this page to complete your kit. You have the option of Diamond Eye's 4" to 5" angle cut, rolled edge, bolt-on tips in either a stainless steel or black powdercoat finish. And if you either don't want to add a tip, or would like to choose a different option, no problem, just select "No Tip(s)."

Throttle pin defective
This carb fits my tohatsu 3.5 hp but the throttle pin is defective. The only way to regulate it running wide open is to choke it out.
