Cat clogged, over heating....

Check engine light

Do like I did on mine the day I got her home from the dealership. Get a reciprocating saw with a metal cutting blade and cut the two pipes going into the converter right iwhere they join, this will leave you enough excess to have two exhaust pipes made that will join right up to the two headpipes. For the O2 sensors, I simply got a set of header collectors with the O2 sensor fittings, cut off the collector part and welded the barrels into the exhaust pipes. I mounted one of the sensors in each pipe, and had the computer flashed up so I don't get a code or check engine light. Then had a pair of tailpipes custom bent to go over the axle and exit in the stock location, and there you have it. No restriction true dual exhaust with a one of a kind sound that is sure to get you compliments. I can't tell you how many times I pull into a gas station or parking lot and someone says, wow, your truck sounds awesome, what do you use for exhaust? And they are usually surprised to find out its nothing but pipes from the engine all the way back. It gives a loud, crackling roar when you rev it up, (kinda like a Harley) a low gutteral rumble when you're going slow about town, during light accelleration it produces an rather loud, powerful crackle that has been likened to a huey, and at cruising speeds a rather quiet deep tone. Losing the cat and single exhaust gave me markedly improved fuel economy, throttle response and acceleration.
