rear exhaust advice

[Deefadog]

I got a full stainless exhuast system on my MK2 (it was on there when i bought the car!)

I don't like the roar from the rear box, just getting to old for all of that now so apart from fittings is there any problems in fitting a standard gti back box onto the system? It will stop the roar yes as i have been told that the back box gives the note!

btw back box from GSF is ?28.50 I was qouted, not sure if that is right though, sound a bit cheap to me

Thanks for any advice

I had a magnex system on mine when I bought it.
The bore is bigger than the standard pipe so a normal back box wouldnt fit.
i took the whole system off, sold it privately on this forum, and used the cash to buy a new standard system.
the car's now smoother, quieter and the new 'zorst has a 2 year warranty.

I am sure there are adapters if the bore is bigger, if not I could get one made up!

Don't realy want the fuss of removing the whole sytem just change the box and stop the roar

Its up to you mate, but the back box is half the system anyway.
You'll not get much benefit from a performance mid section only, even if you can get it to fit.

So what is the whole system because I ahve the back box, then about hald a foot away another large box, the further on up there are two smaller cylindrical boxes! Just thinking of a quick fix

you'll actually find that a std 16v system breaths very well indeed - i've read a few reports on other forums - and there is no real power gain from having an aftermarket system - main power gains are from a aftermarket manifold

as for replacing the back box, it might be easier to keep the back box and remove the centre & middle boxes - that way you at least keep the nice tail pipe

16v's have 4 boxes in their system, though one of them is part of the downpipe

Yeah heard that about the exahusts!

It the damn boy racer (no offence to anyone) sound I want to get rid of!

I have a spare second box in as it came as a replacement and want to fit that and the standard box.
