Title: Help with custom exhuast
Post by: Dead_dub on February 04, 2015, 09:09:35 PM
Hi all. So after selling my old g40 some
7 years ago it's g8 to be back behind
The wheel of one agin.
So my new G has a custom exhuast on but it sounds
So bad. I like it loud but it's well bad. And I want the
Plastic zip tie hanger sorting out haha custom hay lol
It's straight though. So maybe I need a mid box? (Small one)
Has a big twin back box maybe a smaller one?
It's make a really bad droning noise @ some speeds
It's messing with the driving of it.

It's 2 and a half inch. Pipe the exhuast makers
Are telling me to put 2 and a quarter on?
Is he just selling me his pipe haha.

So would like to know what's the best size
To go with.
What's on yours?
I want to best for the car.
The best performance too

Thank all G

Hi mate,

2 1/4 is about right imo, I'm aiming for 180-190 bhp and I'm going for the same so i guess it all depends on what you have/ aiming for? Its only a 1.3 at the end of the day. As for silencer a mid box would be a good idea, guys with turbo's can get away with 1 because turbo'd cars tend to be a bit quiter due to the nature of the setup. I'd add in a centre box first then mess around with the rear box if you're still not happy.

Also a good tip when I'm looking to make something custom I normally go to a local exhaust fitter, they've normally got loads waiting to be scrapped going for free/a drink.

This is my opinion and I'm sure others will have different views... hey if we all agreed the same thing life would be boring

Hi thanks mark.

Yer it's going to a custom exhaust shop to have one
Fitted. Just got to put me hand in me pocket agin hehe

I just want to do it once if you know what I mean

Yer he did say to go 2 and a qu
I want not to sure if he was just trying to sell me some more
Than I needed.

I got a r1 charger and 65mm pulley
And a big vale head.
It use to have a cam in it as well but only made
149bhp at jabber I think it souls have made more
So maybe to big an exhaust is putting the power down

Defo having a mid box lol.

Thanks glyn.
