exhaust instead of lift kit

so my parents didnnet really like the idea of a 1000 lift kit that i would hever use, so im gettin, i hope,  a custom dual exahust with tipps for 260$, the guy has really good reviews, he told me that i should get some where between 10-20hp casue of the bigger pipes i hope they buy it ill post pics as soon as i get it

going w/ 3 1/2''?

i believe so. cantrember the details since it was  few days ago

Isn't 3 1/2 pipe a waste on a Blazer?

I remember is lowers back pressure or something to much.

all i can say is it basicly the exact same as that gree one i posted, identical really

It's 3 1/2" tips that are 18" long. Not a 3 1/2" exhaust piping.. If this site offers that as an kit, that would be awsome. But I truely dought the 10-20 hp claims unless he has a dyno sheet to back that up. Butt dyno's dont count...lol.... Overal this does look good. I was looking into changing my exhaust system too.. Good find.

oh, sry then, didnt see that.

3.5" pipes would be WAY too large on a 4.3L v6 and duals at 3.5" is just rediculous... 

I also don't think that it will be true duals as the computer will definitely have something to say about that as the O2 sensors won't be right...  The PCM uses both the upstream and downstream sensors or catalyst monitoring and the readings would not be correct if going true duals.

And again, engines needing backpressure is a myth.  There is such a thing as going too large and limiting the scavenging affects.  Too large and the exhaust will just slow down too much and stack up.

oopse he said it was gonna be duals rigaht afther the cat, haha forgot about that, and he said hed get the right pipe size for that output, alot of people i know have had ther car done there, they all say yeah its a little bit quick now

Well if it is possible see about getting some dyno specs for it before and after the exhaust to see if there truly is a major difference!!

Looks nice, I have a similar set-up with a Flow 40. That looks a little nicer then mine (mines not all nice and tucked up and I had to lose the spare tire), you have to post up pics and a sound clip when your done though!
