Straight Through Exhaust

[joe blo]

if i take the mufflers out on my r33 will it be really loud? would it sound good or crap?

Is this a serious question?

Mufflers keep the car quiet... So yes, its quite safe to assume it would be much louder.

I take it you've never hear a car with just a pipe?

How much, no-one knows, but either way its going to be waaay beyond legal without a doubt, and im talking not just one block away.

You'd quickly get a headache from it all which would probably teach you the reason we have mufflers

i have just a straight through rear cannon, and nothin else up to the turbo which is loud but i like it, personal preference anyway, although my car isnt a full daily if it was then maybe i would have a different one

ben...

Hey,

Presuming you have a turbo (you're in FI) you will get some performance benefits from deleting mufflers.

It won't be as loud as a NA because the turbo(s) does a lot of muffling.

It _will_ be louder - it depends what you're going from/to; but say you deleted the mufflers from a stock

system on an R33 with a stock turbo I'd guess you'd be looking at around 95-100dB. If you can unbolt

your exhaust behind the cat, try it out to see what it will probably sound like. You probably won't like it

If what you're going for is performance; you should be able to find something that flows more and yet

is still legal by either using a different muffler design (you haven't said what you already have) or a larger

pipe size with appropriate muffling (up to around 3.5"; anything bigger than that is very hard to shut up).

If you're going for performance - but on a budget - look for a secondhand system in stainless to suit

your car. You can polish stainless if you're after the bling factor.
