Is the SLP loudmouth 1 worth it?
 

I currently have kooks headers with a cat delete and a corsa catback exhaust. If I put on a SLP loudmouth 1 axleback on, I know it would give me a little more airflow, but would it make it louder? And if it does make it louder, would I lose that nice exhaust note that comes from the corsa system?

Loudmouth is basically straight pipes. Im sure it will be louder you will loose the exhaust note but since you have a SS it will still sound good.

If you want it LOUD, that would be it. It's loud with stock manifolds and OEM cats. You're running LT's with no cats.

As with most questions on this site, your answer can be found either by searching or in a sticky. There's a nice exhaust sound sticky that i'm sure you could find what you're looking for.

+1. It'd probably sound pretty raspy with LTs and no mufflers. You could always just do a muffler delete for $100-150 and see how you like it. That way if you don't like it, you're not out all that much.
