Once you have installed an indication kit you will want to increase your speed further and gain more aggressive sounds from your stock engine. A high quality stainless steal or aluminium exhaust system will give sporty looks and sound but also give your car the extra power you are fishing for a 2.5” bore will reduce your back pressure and allow gas flow so smoothen out resulting in a direct gain in power and acceleration. Depending on your car and how much of the exhaust system you wish to replace you can pay anywhere from $60.00 to $4000.00 depending on your requirements.
