Exhaust Question
 

I took off the cat and the muffler and I do not like the sound. Sounds like the Tin Man farting. Will it sound better with 4 or 5 inch or do I need a muffler? I really want to hear the turbo whistle. Thanks for your advise.

that tin man fating noise is the what all the lly and lbz make. the noice can be tuned at idle though

if you want more whistsle plug the resonator and mod the intake, if thats not enough then remove the resonator and get an intake.

so the sound is not going to change much with 4 or 5 inch? Will a muffler take out the tin man?

its the vvt, look up some lbz or lly trucks on youtube and they all sound like tin men unless they got rid of the vvt turbo.

the truck will get louder the bigger piping you choose. also lowering egts is a plus

You need a muffler

Do u really need a muffler?? Or can u get away with running just straight pipe?? Cause i cut out my muffler and turned it out infront of my rear tire and then did the air box mod. Now it whistles like crazy!!:U: Sounds really sweet when u rug it:U:

The guys I run with call my truck the retarded kazoo. That is just the tubo.

For exhaust size, I personally like the 5" it gives it a nice throaty sound.
