hey guys i just bought a new civic. it has a b-16. the exhaust is 2 1/4 inch. is there any benefit of going to 3 inch. also have any of you tried the steath black mufflers. the exhaust on the car right now is just too loud so im thinking of getting this exhaust. any good?

the stealth black one will probably be just as loud as its a straight through muffler and doesnt do much to quiet it. If u upgraded to a 3 inch exhaust that would be a waste of money unless youre car is turbo'd.

alright thanks. do you have a suggestion on what exhaust i should run. should i just run stock? or am i losing performance?

The wider your exhaust pipe, the more work the engine has to do in order to push out the hot exhaust gas. Hot air is light but when there is too much in the pipe, the engine has to do more work to exit out the gas.

Having said that, smaller diameter pipe (i.e. OEM size, 2.25") will make exhaust gast exiting faster at low end; which will suffer at high end (restriction). And of course, vice versa.

For a B16, 2.38" is a happy medium. You can go 2.5" for a little more top end power if your engine screams at higher RPM a lot.

As for black stealth muffer, I don't know what that is. OEM painted black? OEM ITR muffer would also be a nice quiet muffler if you want to use that.

the stealth black muffler is made by vibrant.

Apex'i WS II Catback is one of your best bets as far as a performance system that is also got nice sound and it quiet.

i'ld go 2' on a b16. 2.25 on any 1.8s.. and 2.5' and up for any 2.0 and up..

alright well i want to leave the exhaust itself but just want to buy a new muffler. what you guys got in mind? gimme some suggstions.

I bought a used axle back from my friend and sanded and painted it flat black with exteme high heat paint! I like it, at night you cant even see it at all!

actually, the vibrant stealth black are not too loud... they aren't fart cans if thats what you are thinking. they are a straight through design, but the canister is huge on it to quiet it down... if you have a resonator or even better a dual res, i would run it with a nice high flow cat a 2.5" all the way back... and of course some good headers, but even without the headers... thats going to be my next setup.

imported_mikepasini

btw... they have just a nice deep tone to them, if you just cruise around or drive normally its pretty quiet... but, romp on the gas pedal and iti opens up a bit...

also, for me, i would run it without a cat or res and 2.5"... i was saying above that a cat and res/twin res would quiet it down quite a bit.

some people just dont know eh C?

I've found going from 2.25" up to 2.5" on my b16 was one of the best things for it....didn't really loose any low end, like every one says.
3" is for turbo.

imported_civic_66

alright thanks guys. liek i said right now my car is 2.25'' but in a little while my plans will be turbo. so i guess i'll just drive the thing until i pick up a turbo and then just do a 3 inch. thanks for your help.
