When my exhaust recently fell off, a week after the MOT, I searched for anything to replace it. No luck anywhere. MJP suggested PD Gough but they are in Nottingham, I think, no South London. Also they were expensive at £1200 but it was custom made on the car. QuickSilver quoted me nearly £900.
Eventually I settled for a custom made on the car exhaust from Longlife. They have outlets over the south of England. Cost £300. Looks good , sounds good.
Here is what they said:
"A custom build stainless exhaust system for your Nissan 280zx would usually run from the base of the down pipe through to the rear of the car. Included in the base system price would be a standard style 2.5" rolled lip style tailpipe. You can of course choose an alternative or upgrade from our extensive range of about 55 tailpipes if you wish.
Because all of our systems are custom built, you are able to tell us how you would like the car to sound, anywhere from quiet to full sport. The most popular choice is Mild Sport, which gives a slight note when you open the accelerator, yet without being intrusive.
The system is guaranteed for as long as you own the car, and this is a fully transferrable warranty. It's also a "No Hassle" warranty - we believe it is the very the best warranty in the industry.
If you are interested in technical specifications, the system is built in 304 grade stainless steel throughout, and assembled using high frequency TIG welding. All of our systems are built using freeflow technology, so your engine will breathe better than with conventional systems. This usually gives a noticeable improvement in the torque from your engine - particularly at lower revs. We have numerous testimonials from customers who have experienced both improved engine performance and fuel economy.
Fitting is by appointment - we usually require a vehicle like yours for around 3.5 hours while we custom build and fit the system. If you chose to wait with your car, we have waiting facilities with coffee and internet access. If it makes life easier, we may be able to make a courtesy car available while yours is with us. There is no charge for a courtesy car, but there is an age restriction."
Hope that helps someone.
