Information on backboxes please?!

I was considering getting a back box, don't know which one yet, thinking of browsing the stock at a local professional supplier, but I really don't want to run the risk of getting the Ultra deep, monotone, boy racer sound. Or no sound at all.
Anyone able to shed light on this subject? Anything about sizes and tips, shapes and things.
thanks

And would it be worth getting a backbox? A smallish one, maybe a double tip, nothing too over the top.

J.

Also if anyone has fitted a backbox onto their GP what does it sound like?
Thanks.

Seriously, I don't get you - you are a new driver, well not even that to be fair - yet every single post on here is about modding your car - induction, exhausts, ICE

Really, don't bother - you are going to be raped on the insurance in any case, plus you really should concentrate on learning to drive and not be another boy racer

Still, it seems you have more money than sense eh.

Have to agree with stu, wait til you can get ncb before modding.

You will get bum raped for mods like exhausts.

Alright, but just so I know, rather then having to ask in another year or so, does the size, say 4" compared to a 2" make difference to noise?

Basic searches on google will tell you this kind of stuff, no offense intended but you would be better of doing that before posting on here and getting slated.

Oh and yes it normally will make a difference in noise, 4" would be ridiculous on a GP

Meh, I see where your coming from but from
the information I've gathered on here from
the last few days, I tried here first ^^

Better off saving your monies for when you are a bit older and have a more tuneable car

Unless the GP in question was a lovely modified blue T-Jet like mine.

Why a new system, not happy with your 'replica-dlight' system?

Depends if you are talking about the pipe diameter or the tip diameter

Tip

Don’t put a 4” tip on your GP.

If your wanting a tip, go for the sporting one, keep the car looking standard will be best.

I wasn't planning on a huge one anyway I was looking at dual 3" tip, looked nice
