im wondering if im losing power or gaining power do to having .. dc headers ,test pipe and 2 1/4 all the way back with a ws2..if i am losing power do u guys think i should put a stock exhaust or wat ..lmk jw

you're probably gaining a few horses with that stuff over stock, not sure exactly how much, 4-8 hp maybe?

Pothole987

since your doing the exhaust stuff you might as well get an intake for it.
you should gain a bit. problaly won't be too noticeable though

JasonYo

Gaining power definitely, but it might be better with a high flow cat instead of a test pipe. You won't really loose power and you won't have as much of a buzzing sound.

And an Intake would help too with that exhaust.

just remember this, anything is better than stock.

not always true, ricey *** body kits is in no way better than oem bumpers/skirts!!!

You can definitely lose power from not having enough back pressure in your exhaust system.

agreed i think it also means less torque

itsnotfast

And, if it's little enough back pressure you run the risk of burning your valves but I don't think your exhaust is that free flowing.

i have a aem intake on the car...how would i kno if i dont have enought backflow pressure lol

don't bust my *** if this is bad for your car - but stick a wad of steel wool in your exhaust pipe and try driving around. if you notice more power, that means you don't have enough backpressure from that exhaust pipe. The exhaust system must be tuned to the motor, not just "the bigger the better"

the exhaust gas resonates and pulses in the properly tuned pipe/header and creates a vacuum which almost sucks the exhaust out of the cylinders and out of the pipe. If the pipe is too big, the resonation frequency is off and there is no suction and the exhaust doesn't flow out the pipe correctly.

Different cams could cause more exhaust valve lift which might help the resonation effect more but I could be wrong. Bigger exhaust pipes are better suited for turbos, not NA cars.

someone care to elaborate on this plz do...

your missing a cam and displacment. haha no it depends if its an obd2 car you may lose a bit. can i suggest a tune? it will bring out the add on parts true potential.

The ws2 exhaust is one of the best systems on the market for improving BOTH HP and TQ numbers. you are gaining power but im sure its limited beings your ecu is probably untuned. get it tuned to maximize the mods you have made to your setup

ive had that prob b4, sohc's need backpressure to survive!!!!lol

shogee

true but back pressure is not desireable in any exhaust design its velocity, if the pipes are to big you lose velocity,

jdmsir4dr

so what did u do in ur case seeing u needed back pressure

Corksil

boost that b!tch.

the only replacement is displacement.

boosting your car will not increase displacement.

Corksil

only replacement for boost is displacement crackaf00!

aight wasn't clear haha.
