Thought #2: Arrows w/o TPS or Termi's with TPS?

Looking for opionions: Arrow pipes without CPU upgrade or Termis with? Do you have any performance data? I know that the Arrow slip ons are good for about a 4HP increase and the full system and 8HP boost.

Are the differences in performance minute enough that it comes down to astetics in sound and looks?

You are going to need some way to adjust fueling to compensate for the increase in air your motor will be pushing out. This may be as simple as an ecu reflash. If it were my $, I'd get a full system which necessitates ecu reflash or new ecu and tps reset.

After researching my options, that is looking like what I will go for. Full Arrow system with an ECU reflash. I'd rather fo that route. I like the look (and sound) of the Arrows better. Plus, the price of a full Arrow system and ECU flash still (appears) to be cheaper than a full Termi system with the ECU included.
