E-cutout stock front/dump vs. 3" dump/front E-cutout

1. what how much difference really? 5rwkw or so? and 500rpm fast spoiling?

then how about;

2. Stock Dump/Front E-cutout vs. 3" full system turbo back?<---- what will be better?

basically trying to anaylse which will be cost effective with minimum difference

thx

oww no1?

What is this e-cutout that you speak of?

[rev210]

I reckon go a D-cutout or a Q-cutout and prevent things from spoiling fast by keeping it in the fridge in an airtight container.

dump---> front pipe --->E-cutout--->cat---.>cat back--->muffler

ok its a dodgy picture but it represents an exhaust system,

Point 'x' has an electronic flap where it can open and close by a siwtch inside car.

So if it is closed the gases will past into the normal system, which includes, cat. catback, muffler. back to stock

If Flap is open the gases obviously just pass right under the car, bypassing cat/catback/muffler.

which would be hella loud, like a v8.

but things like sitting in traffic the fumes would be really hard to seal completely off? apart from getting raped by the cops also, it would sound alright

P.s. I took my muffler off a few months ago from the cat back, so I only had the front/dump on. It sounded shit, the backfires were heaps loud, and have you ever heard a holden 202 with no muffler? They sounds nearly the same. The neighbours wondered what was going on when I did it lol. Took her for a blat, but I live in a small town so coppers werent too much of an issue

mupkant: would this be the same as a 'screamer pipe'? I am thinking of having a screamer pipe put on when i put on the 3" front/dump pipe....

we "bypassed" the exhaust (unbolted the cat) on my mates R30 L20et for a trip to ec. yeah, sounded fairly interesting, like how i would imagine a poorly tuned 253 V8 with a T-88 hanging off it would sound. the turbo whistle was insane

those valves used to be sold thru street machine in the late 80's. a guy who used to have on his mini used to have it open on thusday night 'MacNats' and would shut it only when a cop appeared. never saw him get busted

I drove my 308 holden with only extractors on and it sounded crap at anything less than 5 grand.

im not sure...

this is just a replacement for an entire exhaust system.

from a flick of a switch you have

1. free flowing ON

2. back to stock exhaust OFF

- daily driving you can have it back to stock nice quietness

- for the tracks or drags switch it ON for performance wise.

good for being a sleeper

imagine a skyline flying past ya, with roaring sound, then you look at its rear and see the stock muffler with 2 small pipes, you'd be "wtf....."

[rsx84]

theres that new back pressure valve, it works from around the final muffler and at normal driving you get low flow and when you put your foot down it opens right up to get max flow, just think of running a 3.5"-4" system with a nice quiet sound till you put the foot down!!
