I've got a 90 Blazer and I'm going to put Flowtech afterburners on it. They are about $150-$200, and are supposed to help a lot in HP and torque

Headmans are cheap, Flowtechs are cool.Stay away from shorty style ones.Don't know how well the puter will take you removing the cat.try unplugging it and drive around awile like that.At least a few tank fulls to see if there is a milage differance.Try and stay in the 2 1/2 inch pipe range 3 inch will suck alot of your low end torqe away.

I have Ceramic Flowtech's on my 89 K5....HIflo cats, Dynomax mufflers, and 2 1/2 pipes...no crossover because I like the sound of duals...it's throaty without being obnoxious, and quiet enough cruisin' so ya ain't gotta crank the tunes so bad ya start clippin' the amps.....did the entire thing, new cats and all for $500...JD
