So my next project for the celi is to do full exhaust. The only headers i could find that fit my budget are all 2.5" o/d.

So i was thinking to avoid reversion i would just do a 2.5" catback as well, that arose questions.

Many people on this site say 2.5" is too big for the st. But why? does it pop or sound bad? Hurt performace?

What are the pros/cons of a 2.5" full exhaust?


Thanks! biggrin.gif
