dual exhaust

[714ms3]

If the tips were 1" smaller, I think it'd look REALLY good.

I agree fully man. But it still looks nice. I want to hear it too........

holy wow. this looks like a custom kit from the back, but a professional kit from the looks of the actual fitment and piping. unreal. looks like i have a custom job for the spring. cant say it will be as show like though. lol.

i like the big tips...it fills out the slots very well.

Might be my eyes or the angle of the pics, but it seems like the passenger side tip is higher?

 

[mazdaspeed32007]

seems like your eyes to me.

me three...just a little itty bitty tadbit smaller and they'd be perfect in my humble opinion

i think the amount they stick out from the bumper is a little too far for my taste as well(too many ppl have tips that go out farther than some truck tow hitches, this isn't as bad though)

 

[Saskatchewan17]

Maybe half an inch smaller and sticking out half an inch less and it would be perfect to me. Wow. Great job though.

sometimes with exhausts its hard to get everythign perfect. i think its a pretty bang up job though. def the best exhaust ive seen on a 3

no we can make it look that nice.. it'll just cost u more money to have it coated.. from the looks of it.. its a fairly easy job.. nothing my pipe bender and welding equipment cant take care of.. ull need to grap some tips and a muffler that fits in that spot they have it in..

yup.. my custom exhaust was'nt exactly centered.. the passenger side was off by a 1/4 inch but u couldnt see that unless looked at it for a while..

Get a factory tip on other side to keep the stock look. There's certainly enough takeoff MS3 exhausts systems available.

Do you lose power because of less backpressure even if you have a high flow cat in the downpipe?

Turbos don't like backpressure at all. On most turbo applications, the less restriction from the turbine outlet back, the more power you will make.

 

[Saskatchewan17]

Yes, the N/A rules of backpressure in the exhuast do not apply to turbocharged cars. The less restrictive you go, the quicker and higher the turbo can spool up.

 

[h0rsies]

so i wont lose any power from the dual? then why do most turbocharged vehicles switch to a single exhaust?

single is less restrictive on inline engines by definition - you don't introduce additional resistance in the point where you do fork.

when the exhaust gets pushed out of the cylinder by the piston it needs some sort of backpressure regardless of being charged or naturally asperated. in an NA applications the exhaust plumbing design along with restrictions like the catalytic converters and muffler create the backpressure. in turbo applications the turbine is the main restriction in the exhaust. superchargers and prochargers are in the same boat as NA when referring to exhaust since they don't use exhaust gasses to charge the inlet air

when you have V configured engines, or if there are 2 separate banks of exhaust, they design the plumbing to help "pull" exhaust away from the combustion chamber through use of exhaust reverberations....ie H or X pipes in some V-8's

in addition, charged engines usually have bigger exhaust valves than intake valves. other way around for NA

Actually that's not entirely true. The concept of the necessity of backpressure on most modern fuel injected engines is more a myth than a reality.

When in the days of carbs and very rough engine tuning, the results from running an engine with a lack of backpressure used to be burnt valves and drop in torque, but that was caused more by lack of adequate A/F ratio at higher RPM's to compensate for removing that backpressure. In our modern world of fuel injection, most ECUs are able to compensate by richening the mixture and/or changing the timing to accomodate the removal of the restrictions at the exhaust.

Backpressure is an age old concept that really doesn't have any place in the world of modern FI ECU tuning.

^^cosign^^

the quad tips look really good. the single tips look ghey.

either way, dual on 4 banger is ghey rice

its for appearance purposes only. the asymmetrical back end is "ghey". call it gay, but when my ride is called gay for having dual exhaust and i smoke some douche with an 8 just for saying that then we'll talk about gay. my 4 beating a car with 2x the cylinders....talk about someone being gay.

i have never seen a car where the exhaust valves are bigger then the intake valves..

i might have been thinking about cam timing being different on charged than NA engines. harder to get exhaust out than incoming air in when your charging the intake
