Cheapest high flow cat for my chevy? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm looking for the cheapest high flow cat that you guys know of. Mine seems to be clogged up or is getting clogged up. I'm pretty sure I have the original cat converter on my truck from the 80's lol. Its huge and its pretty old looking.

Its single exhaust too... not sure what the diameter is. Was it 3"? Just the standard Y pipe that would have came on the truck. 87 model with 350 engine. I want to cheap out on this one. Don't have a whole lot of money since I just bought a boat, and its just the catalytic converter, so eh, not a real fun part to spend money on. I'd like one that's direct fit with the pipe diameter and is high flow.

Universal high flow cats are like $90, nothing cheaper then that.

cheapest is no cat

wouldn't recommend it though. The cheapest you'll find that's pretty good is the magnaflow hi flow, but there are probably cheaper for lower quality obviously

lol, I don't think I could stand the fumes! They're pretty bad as it is. Maybe that's another indicator of a bad cat?

Anyway thanks for the recommendations. Just wanted to make sure I wasn't paying to much. You know how that is.
