Thought I would share something here. I have 2 diff Sets of Header types. One is the Maximizer in the 1st pics that are on my 13 GS350 right now. The other is a Set of Used PPE Headers. Notice the different in configurations, especially the Collector make up.
I plan to one day switch out and Dyno both. I may even do some more crazy stuff to try a squeeze every ounce of hp out I can get on my GS350 including Mid range increase and TQ. I think I know which combo of Tune and Header Collector type might do best on my 2GR.

Reason: grammer
Did you ever run these? On other manufacturers "shorties" give what about they give here in the 2gr land. However long tubes certainly boost the mid range torque a notable amount and the top end power slightly over shorties.
