is something wrong?
 

i pulled into a 7 11 this morning and as i left i notice that my exhaust changed tone. i just put in loudmouths and an x-pipe. i was wondering if there is any sort of like breaking in period or do you think somthing is wrong?

New exhaust has a break in period. the sound will change slightly but not too different than when first installed.

I didnt know about the whole break in thing but I do know one thing for sure....It sounds really good!!!

Yea, that's normal when you put a new exhaust on. It should only last a week or two depending how much you drive it. You're car's alright.

u dont need to break in the slp LM I's there is no packing..but u should be alright...it could be all in ur head..haha

Loudmouth 1's are an empty tube. There is no "break in". The 2's are fiberglass packed. Theorhetically, they might change somewhat.
