can someone fill me in on the difference between ls axleback and itr axleback?

 

alot of difference, the ITR has way more air flow, a shiny tip thats cut at different angles, i can take pics of my exhaust and send it to you if you please

 

I think it flows like 30% better than the Regular integra exhaust, plus it has the better tip

 

the main diff between these 2 systems is the piping diameter. stock ls piping is between 1.91-2.0" whereas the ITR piping is 2.25" all the way back. The muffler itself is the same design except the ITR muffler is slightly bigger a bit less chambered which allows more airflow, the tip on the ITR muffler is slash cut much like the stock gsr tip. In reference to length, the ls axleback and ITR rear section are the same size. hope that helps
