Default SLP Exhausts?

right now my car is set up with pacesetter shorts into two cats to a y-pipe then into a 3" magnaflow catback system. It sounds alright at WOT but you can barely hear my car at idle, my question is if i switch to a slp loudmouth 1 or 2 system will there be much of a difference. I am still planning to run my car through the 2 cats until i dont need to go for emissions anymore.

Car will be much louder and much more raspy. IMO I would keep the Magnaflow and just get an electric cutout. Then when you have the cash, ditch the shorties and get some LT headers.

I have an SLP catback with my shorties and y-pipe. it gets the job done, pretty loud.. but i can keep it down when i need to.

i dunno if all SLPs are like this, but mine is only a single-side tip. Might bother you... i could care less.

The loudmouth 2's are supposed to be less raspy. Personally with cats the LM1 sounds good but without cats it's kind of annoying and the drone is terrible. Have you seen the new setup SLP is offering? It's basically a LM with extra resonators right before the tips. I've never heard one only seen them on SLP's site but I wonder how that would sound.
