I’m looking for a good custom exhaust shop that will be able to build me a road legal system for a Mustang GT. Car has aftermarket exhaust manifold which I plan to keep but neee new catalyst converters etc

Only just seen this, but have a chat with Naz at Powerflow Exhausts in Slough.
He fitted an AWE exhaust I bought for my car (which required a bit of modification that he expertly carried out) and he's also built custom exhausts on a couple of my mate's cars.
He really knows his stuff and has many, many excellent reviews.
Give him a call.

Might be worth trying Wortec near Chichester - they do some lovely exhausts.

Horsham developments in Newbury can do this.

When I bought my current car it had already been fitted with Powerflow back-boxes, but for some reason whoever did it had cut off the hanger on one of them.

The nearest Powerflow supplier I could find was in Slough so I took it there and Naz fabricated and fitted a hanger for £30!

So I'd definitely go there again.

Simpson Race Exhaust in Slough. Absolutely first class and as bespoke as you would wish.

Thanks for the replies. I spoke with Simpson but they said they do race exhausts only. I will try contacting the others recommended.
Car is a 2012 Mustang GT that I use as a track car here in Florida but I’m seeing if it’s possible I can make it road legal if I were to move back to the UK

If you're still in the market try The Exhaust Company, Newbury.
Josh will make you a stainless system for a lot less than others charge.
He'll even tune it to whatever dB rating you require so as not to upset the neighbours.

Agreed. They've done bespoke work for both of my cars. Will use them again in the future.
