Exhaust Experts

Anyone got any previous experience or advice they could offer me. Engine in question is a 4 pot turbo - i know it will never sound good it just needs a bit more volume though as it is too quiet.
Currently got a branded system on which i could maybe sell second hand for 175/200.
another system will be about 600 including fitting so would cost me about 400.
Im hoping to maybe make the current system louder and not go through the hassle of trying to sell it.
Currenr system is 2.75 inch straight through from the standard cat to the backbox - backbox seems to supress a lot of noise as like i say its a pretty quiet system. Would removing the rear backbox be too loud even leaving the standard cat in place?
Or is it a viable option to keep all the pipework and swap out the backbox for a less baffled backbox?
My main concern is ending up with loads of resonance as it currently only has the backbox as the resonator. Would it make more to straight pipe the backbox and fit a resonator in the middle pipework?

What car is it? Some 4 pots sound decent with a louder exhaust, others just sound crap regardless.

Totally wrong it won’t fail an MOT
"You must use your judgement to assess exhaust noise:during the emissions test for the vehicle
rev the engine to around 2,500rpm or half the maximum engine speed if this is lower on vehicles not subject to an emissions test
Exhaust noise from the vehicle must not be unreasonably above the noise level you'd expect from a similar vehicle with a standard silencer in average condition.
DEFECT Exhaust noise levels in excess of those permitted
CATEGORY Major"

How pathetic as this relies on the judgement of a tester who could be hard of hearing or has very sensitive ears & bias against any form of exhaust modification intended to be louder than standard. Gassing Station | General Gassing | Top of Page | What's New | My Stuff
