Exhaust Modification

[R31Nismoid]

depends if your current exhaust is restrictive or not

[r33_racer]

I envy the quietness of your car! After a while off loudness you will be wishing you left it as is and IMO the induction noise is way cooler then a loud exhaust note.

If your exhaust flows well and your making the power your happy with and its nice and quiet. Thats something I would wish for before world peace!

with such a big muffler at the back (it really is big, truck muffler size) would removing the centre muffler make it alot louder? not looking for annoying just a bit of a burble

[KiwiRS4T]

I'm a fan for quietness but my exhaust was too restrictive so took out the middle muffler (don't have or need a cat in NZ) and now it goes well and is still not too loud.

Get a hacksaw (or better still a pipe cutter) and cut out your middle muffler and fit a bit of pipe temporarily. If you like the result get it welded in if not you can weld the middle muffler back in.

A loud exhaust is a good way to annoy the neighbours and attract the attention of the police.

Everyone has a different definition of "loud", that much is certain... and often the law has another view all together...

So do what you want TUF250, but just remember its highly likely any mods will almost ensure EPA's will come your way.

Are 3inch pipes any good for the car? Like say from the catback straight pipe no muffler or anything? could it mess my tune up if i change it? as i have a greddy one?

u mean flutes? be noisy as fark dont think its gona do anything to your performance positive or negative.

I dont want it to be silly, I had a V8 previously with just resinators and it sounded great but it really was stupid and eventually got annoying.

Unless my rb is over 4-5k rpm there really is no noise at all. My dads stock xr6 turbo makes more noise! I was just after a burble. Not into cannons, big resinators only or anything like that. Just wanted a bit of burble not bark.

Thats why I thought id leave the rear muffler (the biggest) and remove the centre but I dont want to make it too loud and get myself into trouble.

its a tricky one...

It literally makes almost no noise. It is completely drained drowned out by the induction noise.

If the induction noise is too loud, why not do something about quietening it, like enclosing it in an air box.

[TUF250]

I have an airbox with a high flow filter, currently on loan to a friend so he can pass a rwc then it will be going back in. once in the car makes very little noise at all, which was my point

3 inch dump pipe high flow cat and lukey turbo muffler 3in 3 out. no police attention but loud enough and seems to flow enough

I have a 4 inch from my T88 turbo back. I had the exhaust custom made with a 4 inch dump coming out pointing at the ground (rotaflo muffler)

It's loud as f**k, on a piston engine it would probably be a little quieter.

Swap your middle muffler for a resinator, should give it the nice burble your after

induction noise > exhaust noise

[wacky_will]

i've just got a 3" system from turbo back. with a single remus muffler. the sound is sweet. quiet when you're not on the gas and the system is nice and straight so a good note

coming down through the gears. but it has exceptional flow at WOT.

I would say to be cautious with mucking around with the exhaust chasing a given sound. Odds are you will end up with 'not quite what youre after' and louder than u want.

Quiet is better id say, and im in WA where you can do whatever the f*k you want

My old R33 was loud as. Good for 10% of the time, annoying for the rest.

The current R33 makes twice the power but is quiet as. I love it. Then again i have a pod so it is dead quiet when chilling and an angry tornado under gas. Best of both worlds.

Maybe look at that mod to make turbo induction noise. I think it is a way sweeter noise than exhaust (as good as an RB can sound at the tailpipe) noted by another post above.

I turn way more heads with all induction noise on this one than all exhaust noise on the last one....

And yeah, Vic sounds very cop-strict so a loud exhaust is going to give you nightmares me-thinks.

Goodluck mate

thanks guys, ended up pulling that middle muffler out, quite happy now, only a touch louder and has a slightly deeper note, still very quiet highly doubt it will attract any more attention.

note. I am selling that straight through 3inch stainless muffler if anyone is interested in a high flow 'quiet' muffler
