Original WG muffler verse the straight pipe....

I was told the factory WG pipe/muffler was "tuned" to bleed-off exhaust to optimize boost.

While I have had the straight pipe on the WG for a number of years I remember going back and forth to see if one or the other had any impact on performance...

I found that the boost "seemed" to hold on a little longer with the factory pipe than with the straight pipe but that the straight pipe's sound was awesome. So I stayed with the straight pipe..
