OUR EXPERIENCE IN PERFORMANCE EXHAUST SYSTEMS & CUSTOM EXHAUSTS: |
Peter Geddes spent many years Drag Racing and as a Co Driver in club rallies. We have sponsored many successful drag cars; rally cars, stock cars and speedway cars. I held many different class records including sports car and gas classes. Needless to say the various vehicles had our sports exhausts and extractors on them when the records were set and rally's won. After forty odd years in the trade there's not much we don't know about various exhausts. Some people call an extractor an exhaust header whatever you call them they replace the exhaust manifold and are designed to improve Kilowatts - Horse Power. We build all types of custom systems, dual exhaust, dual to single and single to dual, big ones and small ones. We custom build systems for flow master exhaust mufflers. We will also fit your own flowmaster muffler. Geddes manufacture extractors for vehicles when extractors are not available. Geddes recommend, supply and fit Coby extractors. |

WHAT DO YOU WANT TO ACHIEVE FROM CHANGING YOUR EXHAUST? |
Before deciding what type of custom performance exhaust system you require it is best that you consider what is the main aim of changing your exhaust. Is it: 1. Looks, do you want a chrome or stainless end or do you want a polished stainless muffler? 2. Do you just want to make your vehicle sound nicer? 3. Do you want to gain as much power from the engine that you can? 4. Do you have a budget in mind? 5. Is it a combination of all the above? We find that most customers want to change the sound of their vehicle. We can spend time with you trying different mufflers on your vehicle to get the sound that you can choose. Geddes carry large numbers of mufflers in stock. Once we know the budget you want to keep to we can advise what range of mufflers we can use and then try those for sound. We have a db gauge so can keep your exhaust noise to a particular level. We can try combinations of mufflers so that you can choose what suits you. This takes a little longer but you have the control over the sound that you will achieve. |

NOISY EXHAUST, NOISY MUFFLER (Sound Check 09 636 7064) |
NEW LAWS Based on information provided. For more information on this subject we suggest you visit the Government web site: At present the NZ laws are being changed. It is up to the WOF inspector as to whether he believes your exhaust is too noisy to pass a WOF. If he says it is, then you can either: 1. Take your vehicle to a Low Volume tester to have it tested and a certificate provided. I have been told the cost for this may range from $120 to $150. However at present even if your vehicle is under the 95 db limit and you get the certificate, this does not guarantee that the WOF inspector will then issue a WOF. The laws still need to be changed before the certificate will guarantee you get a WOF. (These laws will change again on 1 June 2008). We understand that as from 1 June 2008, cars and light goods vehicles that come into NZ after this date will need to comply with the new 90 dBA level. The remaining vehicles already in NZ will continue to be required to comply with the existing rule of 95 dBA. 2. Bring your vehicle to Geddes, we can either quieten your exhaust (can be cheaper than a Low Volume certificate) and/or Have Geddes check your vehicle for sound to see if you are below the limit. We have a db meter and can check the exhaust sound (noise) level of your vehicle. This is only $25.00 + GST and will be a cheaper indication of how noisy your vehicle is. If you have a noisy muffler, then we can recommend an exhaust repair or exhaust replacement for a quieter muffler and exhaust. |

PIPE BENDING, PIPE EXPANDING & REPLACING
YOUR |
WHAT IS A CATALYTIC CONVERTER |
Catalytic converters look like a small muffler. They are a unit that converts the dangerous exhaust emissions into natural less harmful gasses, from carbon monoxide to carbon dioxide and water. Time, abuse and poorly tunes engines cause irreparable damage. The cat can break up and from the cat back exhaust system can become clogged causing extra back pressure on the system and loss of power. The computer may sense the extra heat generated and send the engine management system into a shut down or reduced power mode. |
EXHAUST REPAIRS. |
Short section of pipe, up to 400mm: $58.50 + GST. Catalytic converters or a small muffler & exhaust are often removed and replaced with a short piece of pipe as a cheaper repair. Sections of damaged exhausts & muffler can also be replaced this way. |
CUSTOM PIPE BENDING |
We custom bend exhaust tubing of various grades and sizes 31mm to 76mm to samples or drawings. Our exhaust pipe bender has various attachments, an exhaust pipe expander, a tube reducer and various flaring tools. We manufacture cones and collectors for extractors and headers. We need to inspect your vehicle to advise the various ways of repair or replacement. We are often required to replace from the catback exhaust and mufflers because of performance or blockages. |
EXHAUST PIPE CUT TO LENGTH |
Geddes sell exhaust tube by the metre - we cut to the length you require. We charge $9.00 + GST Plus the cost of the tube. |
