How to quiet down cold start

Hey guys, so recently i straight piped my car and the cold start is stupid loud now. Any way of quieting it down without having to put the cat or muff back on? I know EVO's have silencers for their exhausts and such. Any ideas would be great

SLP Loudmouth. Gives a nice rasp to the exhaust note and muffles it somewhat. Might go that rout as well.
