I have been searching all over the net and cannot get a straight answer but I might get a Spectre cold air intake for my 2000 blazer and i want to know if it will make my engine/exhaust Louder??? also how many extra MPG's a gallon am I looking at?? Im running a super 40 and want more sound!

 

i have a k*n with a stock exhaust and about 3000 rpm its louder. then at 3500 it quiets right down

 

I have a spectre intake with a 2.5" Flowmaster 40 exhaust and it deff made a difference. The intake made a good improvement along with the exhaust made even more of an improvement. With the intake, exhaust and tune, im getting 28mpgs on highway and around 11-13 to local. You will deff hear it when you get on it along with obviously your exhaust will. You have literally the exact setup and year truck as I do

 

28? 2wd or 4wd

and is this being pulled downhill with the wind blowing on your back with the truck off?

 

4wd and no man i swear. 28mpgs i caculated it myself. I took a trip from Long Island NY to Ocean City Maryland and got 28 on the way there with windows open, and i got 24 with the A/C on. The intake, exhaust and tune really helped my truck. Our first gear is nice and low and i uses for offroading and the beach but our low gears and overdrive are great expecially with 3.42 rearends. I have always known these trucks to get great mileage on the "HIGHWAY" never local lol. Tune ups and oil changes are a great thing!

 

I got a nice tone from my CAI and I get 1-1.5 MPG better from that alone. By my calculations the CAI has already paid for itself.

 

theres two different ways for a intake where u buy the whole tube and cone and stuff or just the adapter at the end of the tub and then a confilter on the adapter. havent put one on a blazer yet im gonna put a dapter and cone on tommrow. but i think that Spectre cold air intake will sould good and u could hear the air going in but idk. laster year in my 91 accord i put just a cone filter and i could hear the air going into the engine.

 

Agreed!

 

this sounds about right. my electronic readout says i get about 26 on highway and thats completely stalk. so with intake it should be about 28

 

When you say "tune" what kind of tune are you refering to? Plugs,wires,ect...? or computer tune?
