Hey guys, is there any difference between a NA and TT exhaust?

Is the NA more restrictive?
Are they both a straight through mufflers?
Do they both have 3 mufflers?

Only the NA have the two smaller silencers in the center pipe, I do believe the piping is the same size.
There is different part numbers for the tail pipe, but not sure if the internals are any different.

The TT piping is about a 1/4 inch bigger than the NA. I've run TT exhaust on NA's before and they actually sound pretty good since they don't have the two little mufflers like the NA's.
