Guys i want to get some new exhaust to make my truck sound better. I was going to go ahead and get the whole TRD cat-back system, but i got to thinking. It looks like the TRD system is just replacing my pipes with SS ones that are the same shape with a new mufler. Now wouldn't it be just as effective to buy a muffler by its self and have it put in. It would be alot cheaper. If anyone knows if the TRD or whatever system you have has pipes that are in some way better besides the muffler let me know. Which way should i go?
