Exhaust systems, catalytic converters ,mufflers, muffler tips?
I've been having the same problems but I've been doing some reading. Muffler tips are mostly cosemetic, they are just for looks. They make your exhaust look nicer on the end, muffler is like a fart can they cost as much as 200 but as cheap as 20 bucks. They are mostly for sound and weld or attach onto your exhaust. An exhaust system is from what understand is from your engine to the back of the car, it gives a nice sound and is ussually 500-up in price they are an hp increase and let your engine breath better
catalytic converter, only need for smog,muffler is sound and performancemuffler tip is all cossmetic. exhause piping is sound and performance. next step, muffler style, circle straight style gives more performance and louder sound, oval cannister less performance and lowers sound, exhaust piping should be sized to your engine size.
