does anyone know what i could use to make my car more louder or growl maybe intake or exhaust anything else and can i get some names doesnt matter about the brand just results. thanks guys.

I removed the resonator on mine, love the sound. It's not much, exhaustdepot.com is gonna have an x-pipe available soon for our cars, he did mine.

Care to inform a newbie?

How does an x-pipe alter the exhaust flow (if it does at all), and what kinda changes in the car could I expect if I were to install one? Is is just for sound, for performance, or both? If performance, how much? Thanks.

is removing the resonator a DIY?? and is there any down side to this?? would i have to install a new resonator when i take out the stock one??

You need to cut the back side of the tubes. The front half are clamped and can be removed by yourself. Any exhaust shop can do the job easily and cheap enough as they have exhaust expanding tools for a slip fit or welders.

Make sure you tell the shop doing the work to be careful and save the resonator as it can easily be put back on by reversing the above procedure.

Only downside is if you don't like the sound.

Make sure you ask for X-pipes and not just straight pipes as they are louder.

nbturbos

Not just louder, but they sounds like complete ***. I tried that first and boy what a mistake that was.

An X-pipe equalizes and lowers back pressure between the two sides of the exhaust system. A good X-pipe forces the gases to merge and cross over even at higher RPM. This is what gives a true X-pipe design their charateristic sound. An x-pipe causes no gains in performance as our resonator is not restrictive at all, inside it just has 2 extra chambers.

For a car like C300 though, wouldn't decreasing backpressure result in lower torque? I mean, other than a deeper sound or growl, what's the benefit? Any performance?

nbturbo do u mind putting up a pic of underneath ur car?
narky: little performance gain + better sounds
down side is its bad for the environment and u might get a dirty bumper faster
plus it might worsen the fuel consumption as your ecu is not tuned to suit but thats being said a freer flow exhaust might give u a better mpg on the highway too

cmon guys, think of the mother earth

I believe Remus covered the back pressure issue in their thread. There is enough back pressure from the catalytic's to not affect performance.

nbturbos has mentioned in numerous posts about his modification that he can't see a performance difference as the exhaust is not chocked in any way by the resonator. It's a sound difference only.

IMO the intake and exhaust's(minus headers maybe) are pretty free flowing(plenty of volume and clean flow paths) on these cars so I wouldn't expect much if any power increases to concern oneself with. I am just speculating off past experience and could be wrong though.

Krytech

That's what I read also. I would jump on an exhaust setup if I could get a reasonable gain out of it, but IIRC even Remus said their exhaust offered no noticeable gain as the OEM setup was fairly free flowing.

do you think it would be any expensive job, about how much you think??because i leased the car and dont want to be pouring a loud of money into a car thats not mine i already bought rims tints chrome accessories and hid kit for the car and now was just looking to add some sound for my final mod. thanks

racetested

I haven't gotten mine done yet as I'm unsure of my complete exhaust project but from past experience I can't see more than $100-150. The materials are cheap and the labor is easy.

To remount the resonator if you even have issues will be cheaper yet as it's just labor.

Nick2008914

any idea on how much an x pipe would be?? or if its made for our cars??

nbturbos

$100- $150 is right. If they're charging you more, go elsewhere.

Zankok, none of what you said is true. Resonator has nothing to do with emissions. Mother Earth will be fine. The ECU does not need to be re-tuned so MPG will remain the same and you won't lose any power, just as you won't gain any.

racetested

There are various universal X pipes but best to call a local exhaust shop and see what they have to offer. The pipe measures around 2 1/8" O.D. I'm have only seen 2 1/4" X pipes but close enough for a weld to seal the gap.

Again it's a very simple job that doesn't need over-thinking. If you get a bad install then you just had bad luck as any intermediate installer/welder can do the job with ease.

zankok

ah
I mistaken the resonator for catalyst converter
my bad
that gives me another reason for modifying it now *giggles*

Nick2008914

are there any air filters that are easy DIY that i can buy or order that will increase sound and performance??
