hey i just ordered a flowmaster 80 series exhaust system for my 3.4l, how much hp and gas mileage do you think ill gain?

 

not sure exactly, but it makes your camaro sound A LOT better!!!

 

not much because I heard they dont flow well

 

It Has Been Dyno Proven That Flowmaster Is The Bottom Of Muffler Hp Gain But The Best For Sound...i Think They Said Magnaflow Was Really Good For Flow But It Sounds Bad

 

maybe 5rwhp, 80 series sounds badass, but flowmaster is garbage for performance, if you ever heard a flowmaster on a mustang, you will understand what im talkin about, (they buy for sound not performance), let us know how it sounds after the install! are you gutting the cat?

 

how do you gut the cat?

 

first off, since i dont have to pass emmissions down where i live i gutted my cat, however if you have to pass emmissions where u live then i WOULD NOT gut the cat,

anyways if you want to gut it what i did was disconnect the exhuast at the cat (your going to have to when you put on your 80 series anyways) then i took a 6" chisel and hammered the honeycomb material that is inside the cat until it was broken up enough then i turned the car on and blew the rest of the stuff out. another thing to take into consideration if you have the 2 O2 sensor setup then you will have to get O2 sensor deletes in order for your PCM to run right, like everyone else says do a seach, you will find TONS of info especially on this topic

 

o ok yea ive heard about gutting the cat, doesnt make it louder?

 

louder and less restrictive exhuast

 

uuuuuuuuuuuuuuuuuuuggggggggggggggggggggggggghhhhhh hhhhhhhhhhhhh

 

its gonna sound like ****

 

whats gonna sound like **** ,I have the flowmaster 80 on my 3.4 maro and it sounds awesome

 

does it EVER get raspy?

 

i removed the cat and put a strait pipe in on mine for a short time it didnt really make it louder and it didnt seem to make any more power mabe a ponie or two. but it did make the tone of the car a little deeper.

 

does any V6 EVER not get raspy?
