Making An Rb20 Sound Meatier?

[123456]

Any suggestions? I have a 3" exhaust system, all the way down and it sounds OK i suppose but i want it to sound tuned. Like you know when you work a v8 it starts to sound rough (lumpy cams are popular way to make it sound rougher), same as like a J-ported rotary sounds rough.. what would i have to do to the rb20 to achieve a rough sound? Dont need like smart assed comments either, just wanna know how... I can give examples of cars that sound rough if you like

Straight through pipe all the way out from the front pipe back.

long duration cams with overlap and a straight thru exhaust.

man the rb20 sounds awesome on my car with the 3" exhaust...

try some cam gears...

or record the sound of an old V8 and play it on your stereo real loud

you should heard my NA RB20DE without the extractors on... pwoaaah.

ways to make your car lumpy (note: these methods can also be used to kill your engine)

use ultra low octane fuel... esp if its from Woolworths/Safeway petrol stations and the indian (hey... I'm allowed to say that) the counter has watered it down for the day

remove AFM from car... spray the sensor with thick cooking oil... put it back in

put hole in intercooler/put in leaky gaskets on intake/BOV

play wheel of fortune with your ignition timing

rmove some teeth from your timing belt

that should keep you occupied for a while.

get nice big injectors and dont get the tune at idle to suit the bigger injectors

and it will lump like mine

drop a 454 chev in it.

but take the centre muffler out, and go to autobarn and buy the cheapest, nastiest 3" muffler you can.

WTF at the sudden increase of posts about making everything sound better. Why not just do the mods to make your car quicker and reap the benefits of the sound difference afterwards... the sound if usually a by-product of a worked motor anyway...

Aside from that, cut your exhaust off before the diff like the scummadore owners have been doing for years. Should sound different then.

car is fast enough for the moment, and i couldnt justify making it faster. 2530's just cost to much, better to save and buy a gtr next year when im 21 i reckon. Hmm alot of exhaust cutting advice, im to scared to lose the cat, and i got a like 5" tip and muffler already, so i dont think that side of things would help, umm i would prefer not to make my car unroadworthy, its only got 1 muffler on it currently. I dont want my car to be lumpy because i hit something with a mallet!! i guess cams would be the way to go... What if you got a stroker kit for one of these things, besides the fairly significant power gain, would yuo be looking at a nicer sound? rb25's dont sound as good as rb20's in my opinion and the stroker would take it closer to an rb25, so;;;
