If you are too lazy for the details, bigger exhaust pipes do make the exhaust louder – but only by a little. Exhaust pipes are made bigger to allow better exhaust flow. Instead, aftermarket exhaust also equips a less restrictive muffler – which is responsible for the much louder sound.

What pipe is good for exhaust?

Stainless steel is the most expensive choice. It is also more difficult to bend and weld. There are different grades of stainless steel. 409 and 304 are the most popular grades used in exhaust parts.

Does exhaust pipe size affect performance?

Systems that are too large in diameter can actually hurt performance. As a general rule (when not running a high compression ratio, nitrous, and/or a blower), switching to a performance exhaust system that is 1/4- to 1/2-inch larger than stock will provide you with the best horsepower increase.

What gauge is most exhaust pipe?

What is the caliber of an exhaust? Most headers are 18 gauge steel, most exhausts are 16 gauge or larger, same material unless you have stainless steel headers or tailpipes.

Does pipe diameter affect sound?

Yea it can affect sound but you could be better off just going with an aftermarket muffler if you are looking for a sound change. I’ve noticed smaller diameter exhaust seems to make the exhaust more raspy.

Can I use galvanized pipe for exhaust?

Galvanizing also begins to degrade at about 450 deg F, so it would work for some but not all on the installation. Plus, depending on how much it will need to be bent to fit, it could crack the coating as well.

What is the pipe diameter for our exhaust?

As a rule of thumb, an engine with 150 to 200 cubic inches of displacement (CID) that produces 100 to 150 horsepower (HP) should be paired with a 2 to 2 1/4-inch diameter pipe if you are using a single exhaust system or a 2-inch pipe if you are using a dual exhaust system.

What size is the exhaust pipe?

For engines making 250 to 350 horsepower, the generally accepted pipe diameter is 3 to 3.5 inches. Over that amount, you’d be best off going to 4 inches. If you have an engine making over 400 to 500 horsepower, you’d better be happy capping off the fun with a 4 inch exhaust. Ah, the drawbacks of horsepower.

How to measure pipe diameter?

Direct Diameter measurement is the easiest. Measure at the end of the pipe. 1 1/2″ nominal

How to determine pipe size?

Cut open the pipe you’re replacing. Measure it from inside with a tape measure, since all pipes are sized…
