Exhaust Repair Putty - Why You're Wasting Your Time Underneath Your Car

Exhaust Repair PuttyWe often see exhaust repair putty on old exhausts in our workshop. As we repair and remove rusty exhaust components, we come across the remains of failed attempts to prevent the inevitable blown exhaust. So why does exhaust repair putty not work and why would you be wasting your time trying it?

The main reason why is quite simple. Exhausts nearly always fail from the inside out. That is, they start collecting condensation and corrosion from the inside. By the time you see the outside signs, your exhaust system is actually quite bad on the inside. So trying to push exhaust repair putty into the small blowing hole is quite literally like papering over the cracks. The root cause of your problem is still there, you're just hiding it from sight for a short while. All too often, within a few days you'll begin to hear it once more. And the next pay day is still a few weeks away....

If you have this problem, take a look at our Exhaust Repair page. We often find that it's only a small part of the exhaust that is actually failing. Many times, more than 90% of it is still perfectly fine. For our customers on a budget who need to keep costs to a minimum, we are able to use our skills and advanced cutting technology to remove just the failed part, then graft in a fresh replacement.

Exhaust repair putty can be false economy, have your exhaust repaired properly

Our state of the art Plamsa Cutters make a clean cut around the corroded exhaust, leaving us with clean metal. Then we use advanced cutting, shaping and welding equipment to craft a replacement part, leaving your exhaust quiet and strong. While we can't give the several years guarantee to such repairs, we can generally help keep away that bill for a new exhaust for a few months and give you time to save up and be prepared for it when the time comes for a new system.

If you're worried that your exhaust may be about to fail, give us a call on 01325 362271 and ask for some help with a free exhaust inspection. We'll tell you right away what we can do to help.

Removing DPF - Changes to MoT Legislation and DPF Cleaning Tips

We're sometimes asked by customers to remove Diesel Particulate Filters, or DPF for short. Your DPF is designed to make diesel cars run as cleanly as possible with current technology, though cars often used for short journeys can become blocked, due to the way the system regenerates and cleans itself. Until recently, it was perfectly legal to remove a blocked DPF. The car would run adequately without it, though with an increase in soot particle emissions. However, many people are unaware that a change to MOT regulations in February 2014 now includes a physical check for the presence of the filter. If the car was fitted with one when new, it must be present. While your diesel car may perform fine without it, you will not be able to pass an MOT test without it in place. DPF cleaning is a better way to stay driving.

Example of catalytic converter failure

So what is the best way to ensure your Diesel Particulate Filter continues to perform well and not become blocked? Understanding how the system works is a start, as many drivers are unaware of them. The filter works by trapping soot particles that occur during normal diesel operation, trapping the most harmful elements. Eventually if course, the filter will become full and need emptying. This normally occurs during a session of high temperature running and for most people this isn't a problem. However, if you use your car for a lot of city driving, this doesn't occur and crs used for stop-start driving are vulnerable to the DPF filter becoming blocked. Often the first you know of it is reduced performance and a red warning light.

To avoid this, head for the open road on a regular basis and give your diesel car some good exercise. Many large leasing and fleet operators are now including this advice in information sent to fleet drivers, as any remedial work is often not covered under a manufacturers warranty.

In fact, there's a case for suggesting that city drivers are often better off with a good petrol engine or hybrid, especially when you factor in the reduced cost of petrol at the pumps compared to diesel.

Catalytic Converter Failure

Failure Is Not An Option, as they like to say in those American movies. And indeed, when it comes to your catalytic converter, your car will feel positively ill should the catalytic converter fail. There two images show the result of a failed catalytic converter, with the casing cut away to reveal the interior detail.

This image shows how the internals have failed and then disintegrated. The net effect is that it blocks your exhaust system as effectively as the old fashioned potato up the exhaust pipe. As you can see, there's no way your car can breathe out through that.

This second image shows the undamaged end of the catalytic converter. This thin network of long pipes is how a healthy catalytic converter should look.


Failures like this used to be very expensive, but we are able to replace failed catalytic converters far more cost effectively these days. This page gives more information on catalytic converters and some of the typical reasons for failure.

If you think you may have this problem, drop us a line. It costs you nothing to have it checked out in our workshop.

Golf GTi With R32 Rear Bumper

Added the smooth R32 style rear bumper to the Golf GTi is a great idea. However, this means that your exhaust system will no longer fit... We solved that issue for this customer by fabricating a new rear system that replicated the R32 exhaust system at the rear. Adding a neat pair of stainless steel rear exhaust tips completed the look, the finished installation looking really very smart, even though we say so ourselves.





Rare Toyota Landcruiser 60 Series Here For An Exhaust

Here's a rare old vehicle. The Toyota Landcruiser 60 series is legendary in all of those places that you really need a dependable vehicle for. Simple and very tough, the UK climate of the 1980's wasn't kind to them and you don't often see them any more. This one arrived at our workshop after extensive restoration by it's new owner including heavy duty overland suspension and significant bodywork restoration. He requested full stainless steel exhaust system with a duplex twin exit tail section.

The created the entire system from scratch in stainless steel, meaning that with the investment by it's owner, this Landcruiser will live on for many years to come.




Nothing Lasts Forever, Not Even A Lexus Exhaust

We'd be the first to acknowledge that the durable stainless steel exhausts that are standard on Lexus are probably amongst the best manufacturers exhausts. But nothing lasts forever and eventually, they need replacing. This V8 Lexus GS430 came to our workshops with parts of the system worn out. By keeping the good parts, closest to the engine, we were able to fabricate a complete system towards the read made from stainless steel. Lexus are whisper quiet, but our owner wanted to release some of that pent up aluminium V8 sound, so we created s system using just two rear silencers. The final exhaust tone was nice and fruity without being too loud. We think the owner was quite impressed with the new character of his car.

It's The Little Details...

It's the little details that make the difference, often something you wouldn't notice, unless it was wrong. The rear bumper of the Golf GTi is quite ightly curved where the exhaust exits. So if an owner wants a twin exit tailpipe, then the two exits need to be staggered to follow the bumper's curve. It's something we do on a regular basis and we like to think our customers appreciate our attention to detail to keep their cars looking right.



Oddball Bora - Side Exit Tailpipes

We have all manner of oddball requests for exhaust systems and we're quite happy to build whatever the customer wants. This rather odd Volkswagen Bora tailpipe arrangementb was requested by a customer recently. Not really sure why, but the idea of a side exit tailpipe setup appealed to him.


Ford Capri Twin Turbo Exhaust System

Here are some pictures of a really nice Ford Capri Sport that came to our workshops earlier. Fitted with the curvy Cologne wheel arches, it's a great looking car. Under the bonnet, there was a custom V6 twin turbo engine that the owner wanted us to make a complete stainless steel exhausts system for. We fabricated a complete system from scratch to the customer's specification, all in stainless steel. A great looking car, that sounded even better once the twin stainless system was installed.

Ford Mondeo Stainless Steel Duplex Conversion

Here's a very nice, standard Ford Mondeo turbo diesel we saw recently. The owner fancied the idea of the twin outlet 'Duplex' look, so we manufactured a custom, stainless steel system. For most of these looks, some trimming of the exhaust is required. This was done in our workshop before final fitting and adjustment of the finished system.
