i would only go with 2.25" pipes but if you like to you can go with 2-1/2'' after the muffler for sound... if you where to stand next to my truck at idle where the exhaust exits my truck it sounded great had a real deep sound to it

For the exit, definitely use a larger size pipe. I ran 2.5" out the back to the tip, but I honestly wish I had run 3" instead. The back pressure you're going to get will be from the pipe to the muffler, the rest is just tailpipe and for sound. A larger diameter tailpipe will give a deeper note.

You'll probably lose power with a 2.5in exhaust.. That is if you were to do it all the way back. If you've still got a stock cat, stock manifold, etc, this is a bit of a silly discussion anyway (IMHO).
Want it to sound deeper? Add a header.. It'll sound deeper and perform better. Going stock manfold -> stock cat -> stock pipe -> 2.5" flowmaster -> exit is

He can use adapters or make it work with 2.25.

I absolutely understand that.. My point is that rather than spend $100 on a muffler that isn't going to make any difference over a $20 muffer, you might want to save that $80 towards a header... :-)

Good point, didn't think of it that way. I guess it's too late now but gonna work more hours to save up some money. i usually get the best so im thinking of going with the LCE header. Any noticeable power/torque differences or is it just in our heads, lol? thanks guys for all the advise.
