back box help
« on: 25 February 2011, 13:18 »
i've found a magnex back box for sale thats for a 16v but my car is a 1.8 8v driver, do you think it could be fitted with a pipe reducer easy enough?

If it needs fettling i know someone that will do it but just wanted to know if its too much hassle, its a bargain price so dont want to lose out!

thanks

I dont see any reason why it wont! At the end of the day anything can be fitted with the right reducer, and the bore will be bigger than your standard pipe i reckon so a reducer should do the trick!

So it turns out the backbox was a twin upswept :( I wanted a twin straight!
So what would my car sound like if I took the centre box out? I want a raspy sound with the occassional pop

t.b.h your going to need to modify the middle box as you wont fit the back box with just a reducer as the angles will be out!
best option is fir a 16v middle box and reduce it from the back of the cat (it's handy as the mk3 uses a connector pipe on the rear of the cat which you swap for the 16v version and it will all bolt up ok)

I'm not goin to get it as it's a twin upswept. Cheers for the vids!
I've decided I'm going to just keep standard backbox as the baffles are going and it sounds good but remove the mid box. Will this give me the raspy noise I want? I'm on a very small budget at the moment so until I get enough money for a custom system I want to spend as little as possible!
Was just going to drill a hole in my mid box! Lol

Well that's just daft :huh:

Removing the middle box will give you a little more noise, removing the cat will make it a bit more raspy.

All that will do is it will sound like it is blowing.
