No resonator makes it louder?

[osl]

But how much louder? I'm thinking about doing a generic 2.25 pipe from cat back without the resonator. Not turbo'ing or anything but just want to know if it's worth skipping the resonator.

It's not worth skipping the resonator. It's going to be raspy and shitty sounding, and won't give you more than a horsepower.

[cb7pr]

YES. Sounds like a empty soda can with a few coins inside rattling at about 3k RPM, 10x louder. I know, because I had none for 2 months.

[stretch JDM]

much louder and also cutts back on the back pressure. cops love it tho lol.

Thanks for the replies. I'm not looking to gain power from this. Just trying to cheap out and hope to not have to find a resonator. Does anyone know where I can get a resonator that will fit if I'm doing 2.25" pipe? How long is the resonator and is it OK to just use the one from my stock setup?

What are you talking about cutting back on the backpressure? Backpressure is the enemy.

[cbh23]

Just go to an exhaust shop. They will have one...

back pressure is by far not the enemy... a car with no back pressure will run like shit back pressure is supposed to be there... however too much or too little back pressure can also be bad

Dude, my resonator's gone the day i went on the circuit, its sound way too loud imma record it later on and youll see. And when you absolutly need to drive to somewhere, be careful to not push your luck cuz "cops" gonna like you!

I will redeem myself here and say that needing a certain amount of backpressure is a myth. a car will run fine with zero backpressure. what deviates performance is pipe size, hence exhaust gas velocity and volume to maintain proper scavenging and performance.

There is a thread on this ...I will try and find it for you later!!!

No, whatever ricer told you that should be shot... If they haven't been already.

Probably not a ricer... the backpressure crap seems to come largely from muscle car guys.

Sadly, no matter how many smart people say otherwise, there will ALWAYS be a handful of idiots that say "you need backpressure for performance".

[crazymikey]

I took the resonator out when I installed my 2.5" catback.

Worst sounding car I'd ever heard in my life. So raspy.

Keep the resonator, and dont use a round style muffler.

And I am on a quest to eradicate that...
