Restrictive Exhaust

A restrictive exhaust creates backpressure in the exhaust system that hurts your vehicle's performance in two ways:

(1) The engine has to work harder to force exhaust gases out of the cylinders.

(2) Engines cannot scavenge burned exhaust gases out of the cylinder efficiently. This leaves exhaust gases in the cylinder to dilute incoming air/fuel mixtures and rob your engine of horsepower.

Pipe Diameter

A common misconception is that the larger the diameter, the better the system. But bigger isn't always better. Systems that are too large in diameter can actually hurt performance. As a general rule, switching to a performance system that is 1/4" to 1/2" inch larger than stock will provide you with the best horsepower increases. To determine which pipe diameters will be best for your system, decide what RPM range your engine will operate at, most of the time. Smaller diameter pipes will produce low- to mid-RPM torque. Larger diameters produce mid- to high-RPM torque.

Horsepower Depends on Flow not Pipe Diameter Alone

Bigger isn't always better. Systems that are too large in diameter can actually hurt performance. Improved flow is what you need. Having large diameter pipes isn't what's cool. Going fast and making horsepower is.

Balance Tubes

Balance Tubes (or 'H' pipes) help to even out the pulses in the exhaust gases and balance the backpressure between both banks of your engine. They not only help improve horsepower, but sound as well. To find the right location to install your balance tube, apply a strip of paint down the front portion of the exhaust pipes. The balance tube should be placed where the paint burns off (bubbles) on the exhaust pipes. Generally, put the balance tubes as close to the headers as possible. The balance tube diameter should be at least 75% of the diameter of the pipes with which it connects

Thanks for the tip man. I think I will go with a 2.5 exhaust system on my Stratus

 

i would not go above that it would be useless for you to.

 

Yea. That I know.

Do you know of any upgrades for the 05 Stratus?

 

for the 05 stratus. it all depends on what motor, is it the coupe or the sedan ect......

 

Its a Sedan with the 2.4L 4 cyl.

 

alot of srt4 parts will fit on the engine such as
turbo setup,
plug wires
coil rack

ect........

 

What would you suggest? As in upgrades. And all of the gooooood stuff. lol.

 

look into some msd wires & coil for starters. look around on sites like msd and look at part #'s
