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.

 

Keep us posted!

 

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.
