How to install a performance exhaust on your car

Ever set off a car alarm just by rolling past with a boisterous, ready-to-rumble exhaust system?

How to install a performance exhaust on your car

When it comes to tuning a car, one modification that is high on anyone’s list is to replace the standard exhaust system and allow the car to access the power locked up in other upgrades. Installing performance exhaust systems is a job that is easy enough to do at home, and can be attempted by anyone with decent mechanical knowledge.

How to install a performance exhaust on your car

We have put together a helpful checklist for those that are thinking of changing their exhaust system and are unsure on the exact steps to follow.

Things you will need!

Safety equipment – Goggles, safety gloves.

Lifting equipment – Either a jack and axle stands, car ramps or a lift if you have access to one.

Replacement exhaust kit – Check that it comes with gaskets; if not then buy these separate.

Exhaust sealant – Available from any motor shop.

WD40 – The most useful fluid to any mechanic.

Tools – Socket set; screwdrivers should do it, but a saw may be needed if the old exhaust has seized.

How to replace it

Video Tutorial

Removing the old stock exhaust

To remove the old exhaust system you will want to start with the manifold (closest to the engine) and work backwards.

Usually the manifold can be removed via the engine bay, but it may need loosening and then removing from underneath.

Once you have removed the manifold, or at least loosened it, you will need to lift the car off the ground to allow access to the underneath.

If you do not have access to a car lift (they can be rented locally) then axle stands or ramps will give you enough clearance.

Work your way back from the manifold and remove all parts to the back-box and tailpipe; if any of the bolts or joints have seized then a liberal application of WD40 and force should get them moving.

 

Installing the new performance exhaust

Again, it is wise to start with the manifold and work backwards, but the first step should always be to remove any trace of the old manifold gasket and give the area a clean.

Once you have reattached the manifold then it is time to lift the car off the ground and begin to work backwards to the tail pipes.

It is important that you seal each section together with exhaust sealant, which will cure with heat and provide a rock hard lasting seal.

If the performance exhaust kit is designed to fit your car then the process of installation is simply the removal process in reverse, and all the parts should fit perfectly and easily.

One thing to make sure of is that you are replacing the exhaust hangers in the right places, and that any heat shields are put back into place; as these protect vital parts (such as brake lines) from overheating.

Running it in

Once you have fitted and correctly ensured the torque of all the bolts, and checked that the kit is all in position, it is time to run the exhaust in and make sure that the exhaust sealant is given time to cure and set.

Firstly, you will need to start the car and let it idle for around 10 minutes; the heat will start to cure the paste and the seal will be secure. To make sure of a reliable seal it is advised that you don’t drive the car hard or allow it to become too hot for at least 24 hours afterwards.

Once you have run the exhaust in, and made sure that it is all functioning correctly, then you are free to enjoy the improved performance and improved aural soundtrack that your car will provide.

Great Job! Modified Rides.
