i was looking at the skunk2 catback exhaust systems and there are 3 different sizes. I know not to get the 3" cause that is more for boosted cars. I was wondering which size pipe would sound the best and give the best performance. the 2-3/8 pipe or the 2-3/4 pipe.

 

What kind of cat and header do you plan to use?

 

i was acctually planning on using the stock cat and headers for now. get the headers and cat later. kinda a money issue. What do you suggest? its a 94 integra ls also forgot to mention that

 

2 3/8 will be fine for you then. When shopping for a header make sure you buy a good one, not no DC garbage or it defeats the whole pourpose of the exhaust.
