In between jobs we’ve been working on some new manifolds for our Capri Race car. Proper exhaust manifolds take a long time to make but there’s a lot of calculations to make before the welding begins. Race manifolds need to take into account all sorts of details about the design of the engine, head, valves, cams and even the gear ratio’s and rolling road power plot. Once all of that is taken into consideration the work can begin. You can see from the picture how much is involved with getting so much tube wrapped around the engine bay. The power gains are well worth it though.

Capri Exhaust manifolds
Friday, October 5th, 2012Mini savings
Friday, October 5th, 2012We’ve done a few Mini’s recently, I suppose they must be of an age where the exhausts are starting to wear out. These supercharged Mini exhausts can be eye wateringly expensive and it turns out it’s cheaper to build a life time guaranteed stainless steel exhaust than buy a standard replacement. The last few we’ve done have been in a larger bore and with better boxes for improved performance. The exhaust gives off a purposeful growl but is remarkably quiet for a free flowing exhaust on a supercharged car. It’s the perfect solution when the time comes for a replacement.

Tuesday, August 14th, 2012classic BMW under renovation
Friday, April 27th, 2012After having a mad run on modern BMW’s wanting Diesel Particulate Filter (DPF) removals we had this little classic come through the door. The owner was taking the time to bring the car to date as he carried out a rolling restoration. Items such as Poly bushes in the suspension, uprated brakes and an air-conditioning unit are all either done or being done. This type of gentle modernisation is a speciality of ours and is the ultimate in recycling. You can drive around in a beautiful car which can keep up with modern traffic whilst knowing you’ve saved the planet by avoiding another car going on the scrap heap. Our part was a simple stainless steel exhaust build. The customer wanted a little more noise but nothing excessive. We kept the number of boxes to a minimum as this helps reduce the cost too. We look forward to seeing the cara again when it’s completed.
Classic Ford Capri Custom exhaust
Friday, April 27th, 2012Signum Silencers
Tuesday, November 29th, 2011We’ve done loads of these V6 signums now, and pound for pound they must be the best exhaust to do. The car should have 2 huge boxes at the back but without them the exhaust isn’t loud, it just has a nice growl to it. The back boxes go in the bin and we build some simple pipework with the customers choice of tips. Good looking, great sound and really cheap as there’s not much involved. Everyone’s a winner.
Rolls Royce Repairs
Tuesday, November 29th, 2011If you’ve never driven a Roller you won’t be able to appreciate how effortlessly luxurious they are. This one was in need of some exhaust work and the owner wanted a full copy of the original exhaust in stainless steel. There are a lot of exhaust boxes in the twin system to keep it silent and the owner couldn’t stretch to having it all replaced, especially as a lot of it was still in remarkably good condition. Instead we built the required parts in mild steel and repaired other parts where required. The final bill was a fraction that of what he’d expected and he wafted off into the sunset, another happy customer.
Ferrari Jigsaw
Thursday, September 8th, 2011
This Ferrari P6 kit came to us for an exhaust build. The engine is from a 355 so I think it’s fair to say it’ll be loud. The problem is the car needs to meet the IVA compliance of 99db and have catalytic converters. the engine needs to breath freely though matched length primary headers and have it’s secondary air system, temperature sensors and lambdas included. The customer also wanted quad tips and a cross over adding, all in the space of about 3 feet and without fouling the closely fitting body. That’ll all add up to a challenge then. We just about squeezed it all in there, the pictures speak for themselves. The finished article looks beautiful but as the car is incomplete we couldn’t check the noise levels. we’ll continue to work with the customer though until his creation is on the road.
more dodgy DPFs
Thursday, September 8th, 2011Particulate filters are the latest emissions control idea for Diesels. The only major problem is that they have a life span as short as 30,000 miles if a car only gets local town use and the dealers consider their £2000 replacement costs to be an acceptable service charge. Personally we feel that’s a more reasonable cost for a new engine, never mind a wearing component that you’ll need to change again. because of this we do a lot of DPF removals. We bypass the filter assembly and the car then gets sent to have the ECU decoded. the whole lot costs around £200 to £500 and you’ll never need another DPF. You’ll also gain a bit of power as an added extra. This BMW had a full stainless system built for better performance and had the car remapped while he was at it. It produced driveshaft snapping torque figures once finished.
