obviously a full exhaust system is better but is it a big loss if i choose to go with a catback exhaust only
It's worth going turbo back if you can afford it. You don't have to do it all at once but you'll definitely notice the difference between the two options.
When you compare to stock, neither options is a loss.
But for the effort involved, a full exhaust will give you much more.
if going for an exhaust stay stock or go full out.
going with a cat back, you'll eventually want more flow and spend more than if you had initially gone with a full exhaust
what about if you have headers, stock piping and cat and a aftermarket muffler?
Check out my BIG PART OUT!
thanks for the feedback guys have perswaded me to go ful
My AUDM S15 only has a 3inch catback and a pod filter, made 161rwkw so if you're on a budget...you can still get decent gains on an s15.
any upgrade from stock will give more response and some gains, of course a turbo back would give more gains than just the cat back though.
