i am putting together a gasr wit a compression of like 12:1 and i was wondering if a 3" exhaust is too big? will that will not give me enough back presure?

 

A 1" exhaust will give you plenty of back pressure. You won't make any power, but what the heck

 

whats that mean i know the smaller the exhaust the more back pressure you will get

my question was is a 3" exhaust too big.

will i have enough back pressure if i use a 3" catback?

To small will be no good just as 2 big will be no good...........2.5''-3'' will work wonders depending on the setup

 

Back pressure =bad.
Clear enough?

 

get the biggest exhaust you can so you can scrape the ground like bobby brown.

 

Why do you want back pressure, the purpose of a bigger exhaust system is to free up back pressure. Why do you think drag cars run open header at the track?

 

one of my friends said that his car will hit vtec better when he puts an exhaust on his car

and someone else told me that 3" is too big and it would make the car slower

 

You need to choose your friends more carefully. Don't listen to self proclaimed experts. A 2 1/2" exhaust is usually adequate for most all motor applications, but we have even seen some cars benefit from a 3" exhaust. It won't hurt you or make your car 'slower'.
