Exhaust question
Hello everyone, i'm new here and this is my question
I just bought a 87 F150 4x4 witha 302...the guy i bought removed the cats and mufflers and put glasspacks on and both pipes exit infront of the rear tire on the passenger side, my question is is this to free flowing for the engine, as in the engine not having enough back pressure, and is it bad for the engine, i've heard that its not going to harm anything, but i've also been told that my valves might burn up on my engine.
thanks, chris

the old 'burn up the valves' trick is a wive's tale that people started when they ran without exhaust at all. They would be very hot, and then when you shut off the engine, cool air rushes in and shocks everything.
Emissions is your only real concern.

No worries with hurting the engine, but it will sound a lot better if you put some sort of crossover or x-pipe on it to allow both sides to flow together. It will give you a much more even-toned sound. Just my 2 cents.

thanks for the input guys, i'm happy to know that i don't have to fix the exhaust right away, but yeah it will get some sort of dual exhasut system in the future. the truck does sound pretty mean with the glass packs.
