We just got my girls FRS back today. Installed this visit Borla UEL Header. Works Automotive resonated front pipe and Works over pipe. Also got a ECUTEK custom tune.
We already had an agency power cat back muffler and AFE intake. The base we had with existing parts was 150.3 HP with 118TQ on this particular dyno. After new parts and tune we are sitting at 164.9 HP and 129.6 TQ. Also had him extend the limmiter up by 200 rpm.
I wish I had him do a dyno before the tune, but both of us suspect the tune did not add a lot of power.
We got 173 HP on a mustang dyno with the old parts. I will run it again on the mustang to see what the tune and parts got on that one as well.
My Girlfriend and I defiantly notice the added power.
It sounds sooooooo bad ass now. But the audio on my phone does not do this thing justice.
Also the odor from not having any cats is not very bad at all. Especially comparing it to my uncatted supercharged Celica.
