second topic is what is better to put on first and cold air Intake or exhaust? and what does the Intake affect?
personally, i'd go with exhaust first..but thats purely a matter of opinion. to me, an exhaust is more noticeable and will usually add 1 or 2 more whp than an Intake
just affects how much air goes to your engine for combustion. aftermarket Performance Intakes
have a wider diameter, and this allows more air (and thus more oxygen) to enter your engine.
