Hi all

I've got a little wait before I get my hands on my very own turbo but in the meantime I'd like my sport to sound nicer.

How much difference will it make to put on a h&s backbox? I'm kinda hoping for the nice flat 4 burble but is this realistic just changing the backbox and on a sport?

Forgot to mention that with a standard box compared to a turbo, it just sounds pants!

the burble is there, just needs to be unleashed!!!

i have a GL N/A car inside the burble is nice, but on the outside.... unless you are right by the rear box..nada

let me know how you get on.....

I ain't got a burble at all! maybe very slightly on idle but thats it.

On a Sport with a N/A engine you will not be able to get the flat four burble, unless u get a turbo manifold and something to go instead of the turbo to link the manifold to the up/down pipe. because the N/A engines have equal lengh manifolds unlike the turbo's that have un-equeal manifolds. If you put a fill sports exhaust system and a lest say a Blitz Nur spec back box u might beable to get a small rasp from the exhaust, but nothing compared to a real turbo's flat four rumble. sorry.

hope this helps

the usual suspects (H&S< SS <TSL etc) will release the burble even on a NA motor, go for it, dont expect any performance increase but defo for the aural pleasure

beg to differ... the N/A gl has a layout similar to a leggy... the manifolds join the cat in a y formation, but one pipe is longer due to the shape admittedly not a huge increase but enough to upset the normal flow of gasses hence the burble....

based on your theory (no offense) my saab 900 should not have had a burble, as it had an equal length manifold .... and exhaust....

but burble the 900,s do

I thought the burble is because it is a turbo engine and the exhaust layout, I have heard a sport and it hasnt got a rumble to it at all it's more raspy.

My sisters sport has a group N backbox and that burbles like a turbo

Alot of Scoobs here in ireland are NA due to insurance, most have the burble, i reckon a decent backbox will release it...

me and my mate who brother has an import WRX and were discussing what makes a burble on a turbo and found out that they have un-equeal manifolds, but a sport does not - it has a equal manifolds?? well thats the answer that we came to anyway.

Get a Ninja, definitive burble on a Sport or Turbo. No question.

I understand that it's the manifolds that cause this but I'm unsure what the manifolds are like on a sport

Bottom line is:

With a decent backbox they do. Don't know why, don't care why

The Ninja should work on th NA....my adivce?? Save hard and get the turbo!! Or do what i did and ask the bank manager nicely and borrow the money and buy a turbo tomorrow!!!

I had a Magnex Back Box on my old Sport and it sounded great, go for it you will love the sound.

I had a Hayward and Scott 4.5" Afterburner backbox and straight through centre from Scoobyworld on my old MY00 Sport and it burbled proper...it was even known to pop a little
