Hi guys...
Just wondering if anyone knows the size of the standard exhaust piping for an LS???

I've just got a muffler installed and is DAMN LOUD! Totally unexpected because its the loudest exhaust i've ever heard, no exaggeration. Gives me a headache when i drive...shouldnt have gone for the cheap one

Well, to the point - i want to know what to do about this problem. Thinking of replacing the standard resonator with a bigger one, and wasnt sure whether to upgrade some of the piping at the same time - to 2.25"? Its currently 2". I dont want to change the muffler coz i really like the look of it...

thanks!
