New Exhaust

I am finally going to finish off my exhaust with a new cat and eliminating the first cat. I hope this will make a difference!

Eliminating the cat straight up makes a difference. In performance and the tone of the exhaust.

I love the tinny noise you get from hollowing a cat. Lump hammer+pole+cat=fun ^^

[ps. by cat i mean catalytic convert. obviously

]

High flow cats are a bit pricey, i prefere my method

lump hammers are the shit.

if you nix the cat you have less back pressure, you will lose low end torque and you will throw a CEL. get a good hight flow cat and you should be good.

Or weld a pipe through the cat and leave it in for MOT.

Besides I've still got a centre box and backbox for back pressure

It's really hard to explain, you usually hear it on old redtop cavaliers.

Once you hear the noise you'll say 'Ooooh, that's what you meant by tinny

Too hard to put in words, it sounds like exhaust fumes belting off hollow tin.
Sorta.

..Only sexier

it sounds like a bumble bee farting in a coffee can. like every civic out there

Actually it's not at all like that. It's not high pitched whiny or anywhere near as annoying as civics.

Maybe my really bad use of words trying to describe a sound without using the word [tinny] led you to think that, but it's not that raspy whine you get from civics...

At all.

Just my 2 cents worth here and nothing personal.

I'm young enough remember back to the 50's when smog control was a breather pipe running from the crankcase to open air.
Back then "emission control" was a condom.

And guys ran dual "straight pipes" out of flathead V8's Fords.
Wo0o0o0o0o-Who0o0o0o !!!! now that was loud! A straight piped Harley Davidson couldn't hold a candle to that !

So, have fun while you can with your 'tinny' sounding smog emitting 4 cylinder.
And know that strict federal, state, country and even world smog control rules are nippin at your heels.

Not atm no as the car hasnt moved in a while. I'll try and get one soon. Need to set my fuel pressure regulator as it splutters at low rev when you're WOT

Your's sounds nice, mines isnt that loud, it's just nice, sounds nice, not loud at idle which is what i wanted, so i can sensibly drive it and not sound like im going flat out :b
