Flowmaster

It maintains a token amount of backpressure so heads/valves stay cool, EGR does it's trick, O2 is metered properly and the ECU stays happy without tossing codes. And that's my . I got an immediate 11% gain in MPG with my muffler setup before I opened up and modded the intake to match it.

Forgive my ignorance, but what is a "750," and where would it fall in flow rate compared to say the flowmasters and ravins? Is that the muffler setup you're running?

[wolfox]

The number is just a model number indicating mostly inlet/outlet size, position of those pipes on the body cannister and relative flow rates. FloPro gives numbers to subsets of products with names. (I.E. FloPro Turbo 400, FloPro Twister 530, etc, etc. Mine is a straight, no nonsense oval FloPro 750 with an intererior, single baffle design that's seam welded)

Where it fits in as far as flow rates? 1st, really - followed by Ravin by a very close margin to be nearly identical, really - and then Flomaster at roughly 1/3 less flow rate. If you ever bought the complete FloPro kit in a box, there is a sheaf of paper with installation instructions and the flow charts based on a static water supply flowing through the muffler's innards vs other popular brands. Why they use liquid for testing instead of gas is a little of a mystery to me, but understood - as I use dynamic liquid simulation software to gage and design stuff that flow gasses.

you dont want free flow cause you loose all your low end torque

true you do lose some low end torque, but what it does is shift the power curve of the engine to the right, and in the end you'll have more torque in the higher RPM's and it will net you quicker 1/8th and 1/4 times.

Dude, Cherry bombs are not all glass packs.

i always thought they were. thats how they are listed in jegs, summit, etc. if they aren't all the glass pack type, my bad.

Sorry, my reply might have a sounded a little abrupt, it came across wrong.

They are all made by Maremont.

So you can just use a universal design right? What are the specs, inlet/outlet, center/offcenter?

Well, they will have to weld an extension pipe on it.

2 1/4" offset inlet, center outlet I think.

Some of those Cherrybombs are reversible, changing the way exhaust rolls over the louvres inside the body tube. One way, it makes a rich, mellow tone and nice growl at launch. The other way around does the same thing, but when you let off the throttle, it doesn't dampen the random ignition of unburned fuel in the pipes, making a nifty pop-a-pop-popity-pop as you decel from highway speeds.

I reversed a FloPro Turbo series muffler that was just a resonator can, similar to a glass pack on my Scooby with that 2.2 flat-4. Awesome sounding machine after all the go-fast parts went in, without a ricer fart pipe on the back end. It just sounded mean, and being all plain white, no pinstripes,stickers, nothing - quite a stealth sleeper. It scared folks when I would pull away from them @ WOT at lights, or playing in the sand/gravel where you have to snap the throttle for drift-like turning utilizing the built-in AWD.

ehh i went with the flow master any. The speed shop down he recomended it and i got it for 65 bucks with a lifetime warrenty. If it doesn't work out then i can just buy a new exhaust.

I think that I'm going to go with flowmaster, on my Blazer, too. I've already got them on my Impala.

I saw some tests a while back. If I remember correctly the Vortex flowed about 300 and had more horsepower. The flowmaster only flowed about 250, but had more low end torque.

That is probably due to flow restriction and backpressure.

Nice i have one on my 95 Impala SS to

My flowmaster on my Blazer sets it apart from the rest. Get one.
