what size is the ITR rear muffler section?

and would it be a too much of a restriction for a B motor setup?

currently running a fireball exhaust but im getting sick of that exhaust noise.
dont get me wrong, i love that tone that its producing but its getting annoying plus i dont wanna risk getting the cops on my @ss.

so i was thinking of getting an ITR rear muffler to replace it. will it be the same in exhaust free flow?

thanx.

 

I've been in the same situation, I'm getting so tired of my exhaust noise, but I was talking to my autos teacher about it today and he suggested adding another resinator or changing my current one, it will muffle the sound a little and make it a lot deeper and thus somewhat quieter. Its not the answer to your question but maybe a suggestion of a direction to take. I'd also take a look at the ES oval muffler, it looks a little like the ITR I think and sounds a little like it too
