If you are asking yourself if you should install an aftermarket performance exhaust or if they are worth the cost maybe we can help allay your fears in that respect. First of all, race headers are undoubtedly one of the simplest changes you can make that will generate an improvement in the way your engine performs because they are primarily a bolt-on application. They function by making it simpler for your engine to work exhaust gases out of the cylinders and they accomplish this by affording each cylinder with its individual exhaust pipe of equal lengths resulting in each cylinder’s exhaust gas being given the opportunity of arriving in the collector evenly with an absence of back pressure and consequently improving your engine’s power. If you are considering headers then take the time to peruse the LMPERFORMANCE web site and learn about the headers from the inimitable AMERICAN RACING HEADERS, a company that has been in the business of making headers since 2005 and with the goat of making a header that would be well received and problem free.
