How to Make a Straight Pipe Exhaust System

How to Make a Straight Pipe Exhaust System

A car owner who is trying to give more horsepower to his car would have to remove all the restrictions if the exhaust. You have to let the exhaust gases to flow smoother out of the vehicle. Because catalytic converters are very restrictive, many people opt for straight pipes for their cars and trucks. They eliminate the catalytic converters totally. Depending on the State you live in, this could be illegal but if you are using the car for performance or only for drag racing and not for everyday purposes, then it should not be an issue.

1. You have to raise your car or truck using high quality jack and jack stands. Make sure that it is secure to go underneath before doing anything with the car.

2. The next step is to find the catalytic converters on the exhaust system. This is an oval shape part of the system and it swells out. Depending on the year, it would have had some louvers or vents. Using a reciprocating saw with metal blades, cut your catalytic converter from the exhaust. Make sure that it is a perfect cut that will produce a straight line.

3. Get the replacement tubing that will be placed where the catalytic converter used to be and then mark the tubing using a permanent marker to cut the right length. Again, using the reciprocating saw cut the new tubing at the desired length.

4. Using the MIG welder, tack weld the exhaust tubing that is between the two cut sections of the exhaust. The tack weld is a small and fast kind of welding that secures two pieces together. This however is temporary. You have to make sure that the alignment is straight and that there are no gaps between the tubing before a permanent welding could be done.

5. Get your welding gloves and helmet on and fully weld the tubing together. Make sure always that the tube has no gaps to ensure that there are no leaks.

6. Take the jack away, clear everything out and test your car.
