Years ago I picked up a TRD exhaust off some kid for dirt cheap. I never expected any performance gains, but I do love the sound of it. Right now I’m upgrading the rest of the exhaust and other parts. I’m wondering if the TRD catback is gonna hold me back from any potential gains. Im going with a Gruppe S catless header + overpipe, Invidia catless front pipe, Injen Evolution intake, and a OFT Tune with E85, so I’m expecting a decent power bump. However I probably am not ever going to go turbo.

I know the TRD is 2.5” except for a section that is 2.25” for some reason. The Invidia is 2.36”. As much I love the sound of the TRD, I’ll likely get a new catback if I would be losing any potential gains here.
