does an exhaust reduce mileage?
- Thread starter ProFiver

i find the best thing for milage regardless of mods is going to be driving habits. you can get a few mpg from this or that, but you have to watch how you drive. I got 13 mpg at buttonwillow redlining it every shift, but i can get 35-36 on the highway keeping it at ~72 mph
also it depends on the type of driving you do normally. to save gas in the city learn to anticipate lights and accelerate and decelerate slow and smooth, dont use the AC, shift early. On the highway keep the windows up (using AC is fine) keep it under 75, reduce aerodynamic drag (remove roof racks, etc)
i dont think getting an exhaust will improve or worsen milage to a significant degree.

with all my mods on teh 1g, i went from 32 mpg to 35 consistently. thats conservative driving, under 85. thats not that bid of a difference, but exhaust/intake/etc helps the engine breathe better, making it do less work = better gas mileage
Performance mods such as exhaust and intake do help... the problem is that the driving style usually changes after you modify those two things. Since there is more noise... you usually shift at a higher rpm because you like hearing the noise, which in turn makes you use more gas.otmsp said:performance mods dont really help mpg.The answer is NO.
I just took a trip from southern utah up to northern, was stuck in traffic for 1.5 hours, and the rest of the time averaged about 80mph, and still got 32 mpg on the tank of gas. All i have is a injen CAI and a custom magnaflow exhaust.
The stock MSP exhaust is an RB exhaust, different than P5ProFiver said:this just in...is the stock exhaust on the pro5 the same as the stock exhaust on a mazdaspeed? i wud assume it to be since that turbo would need a better way to relieve itself?
oh yeah anyone got a rb exhaust system to sell?

i just got 30mpg without trying. Must be the Unichip leaning things out and saving me some gas! haha
yes your prbly right.but just the fact that one adds performance mods to a car means you`re looking for hp and to make that you needs GAS lots of GAS >.so the answer in my opinion is no hell no you wont save gas with an exhaust or much less cai and s*** like that .....I know i have lots of mods and if any mod would help mpg it would be something like an afc or unichip or such.my 2 cents.wipedawg said:Performance mods such as exhaust and intake do help... the problem is that the driving style usually changes after you modify those two things.

Better airflow (i.e an aftermarket exhaust) will improve engine efficiency and overall improvement in mileage.
...oops i meant "i assume NOT to be the same"
sorry lots of stuff going on at work...haha

but he wasnt asking if it helps, he was asking if it decreases
and yea i dont think it will matter as long as you keep same driving habbits then youll keep getting about the same mpg
true! (thumb)SkinnyJoint said:but he wasnt asking if it helps, he was asking if it decreases

well i have been driving conservatively...you know accelerating smoothly and stuff, trying to coast whenever i can, and anticipating stuff. jus trying to get the most outta the crazy gas prices...prices have been going down tho. seeing 2.69 and 2.71 in san fran.
