4" exhaust

[One Old Dog]

Ok, here is a question. I have a va,boost,and a BHAF, plan on putting in some dd2' will i have to go to a 4" exhaust or can I just take everything off the 3" and add a walker muffler. Thanks Joe

You will get lots of opinions here!!!

I think a straight-through muffler will be enough. If you are planning to go much farther with the HP, then you may consider going to the 4" now.

The 4'' is nice to have though.
