It was a place in Walsall. This is the reply I received from them a while back..
"The Dual Exit Back Stainless Exhaust System ( mid & rear section ) you have requested for your Alfa Romeo will cost £375.00 , which is fully inclusive of VAT & fitting . I have included quad tailpipes in the quotation. We carry all the necessary parts needed to build your exhaust system, and any bumper modifications are included in the price quoted.
To make the most of a new exhaust system many of our customers take advantage of one of our ECU remaps. The benefits of an ECU remap include better drivability and fuel efficiency (3 - 5mpg extra). Should you wish we can offer you an ECU remap to accompany the exhaust system at an additional special offer price of £325.00, all inclusive of VAT. Power levels vary dependent on the current set-up; an approximate increase of xx BHP over the standard/stock set-up is achievable.
We do require your vehicle at our premises in Walsall, West Midlands in order to manufacture & fit the system. As a guide it should take no longer than 3-4 hours to build & fit the system to your vehicle. If you choose to wait with your car, we have a customer lounge with refreshments, SKY TV as well as internet access. We are also only a few minutesí walk from the city centre should you decide to go shopping etc. whilst we work on your car.
Having a custom built exhaust system from MIJ has its benefits. You can tell us how you would like the new exhaust to sound, which can be fabricated to sound from quiet to full sport. Our most popular choice is a mid-sport setup as this gives the best of both worlds, non-intrusive but achieves a sporty tone upon applying the throttle. All our systems are free-flowing which can increase the performance and efficiency of your car."
