Yeah, but you didn't use a Slip-on exhaust to make it sound like
THAT, did you?! :shocked: See my & other's answers in your thread. Good Luck! :thumbup:
Back to Mc Llyr's question, as other's have already suggested, the short answer to that question is
YES, they can! 
hyea:
And expanding on that a little, an RLS (or any Cat Delete/Cat Eliminator for that matter) will generally also help add a little more 'mid-range' grunt, albeit possibly at the expense of losing a little 'low range' torque (the RLS Cat Deletes have largely resolved that tho!

) so you've got
TWO basically viable Options Mc Llyr, plus one more '
extension option' to change the sound.
- You can fit a Cat Delete with the Stock Muffler;
- you can fit an alternative Muffler in place of the Stock Unit, ie, your original 'Slip-on' option (IF you can find or make anything that'll actually Fit); or as the extension option,
- you can do both - Fit a Cat Delete AND an a/mkt Muffler Replacement!
And luckily for you, RLS Exhausts
