I'm trying to make my truck louder, right now I'm just running stock manifolds w cats still on going back to a y pipe to a dynomax muffler, it sounds good but I want it louder, what muffler/headers set up will be the best to make it louder?

 

remove the manifolds completely. Open exhaust ports for life

 

Gut the cats

 

Agreed, gut the converters and it'll crackle and rasp and maybe wish you didn't do it lol.

 

speed engineering full exhaust.

 

LT Headers will make your car loud with just about any muffler combination.

 

Get some 1 3/4 long tubes and a catless y pipe and keep the dynomax I ran that exact setup dumped on a 4.8 sounded good and was loud if you want anything louder then that you won't want it any louder I guarantee it especially if you're running a decent size gear or torque converter

 

If you can't make your ride loud with a hack saw and 30 minutes you should probably try a different hobby. lol

 

werd.

I did this with my old Tacoma. It even cost me about 7 stitches on my thumb when the sawzall jumped and came down on the top of my thumb. lol.
