The GR Yaris Gets a Garage Whifbitz OPF Back Exhaust System. With Back to Back Dyno!!

Today we have a short video from where we fitted a Garage Whifbitz OPF back exhaust system to my GR Yaris. We also did a back to back dyno run to see if there are any horsepower gains from the system. If your interested log on to Garage Whifbitz website or social media found here:

Without music guys would be a great and accurate video!

How stable is this side to side / does it have much wobble or play?

[UlTiMaTeShtZ]

I’m gonna get their titanium version when it comes out, was your impressed by the quality of the welds?

what is OPF? Does it have particulate filter?

Looking good - sound too ( be better if music was dropped when trying to listen to the exhaust note - probably my age 😂) lm 58 and l have all sorts up to £35, 000 (That being the GR4) I have had BMW M235, M140, Focus RS MK2&3 (all 👍) Audi RS3 (🥱) Mercedes C63 (👍) Subaru WRX, (👍) Skoda Fabia VRS 1.9 tdi (👍) and l can quite honestly say the GR4 is brilliant- bar the sound - sounds great inside when nailing it though !

why this noise from the music.... have you a video without this noising music??

Hi, I just wanted to ask what your long term review is on your whifbitz exhaust? I'm very close to pulling the trigger on it, it's a great price when compared to other systems and sounds pretty good too with no obvious drone, would you agree? I will be going the opf back so it's mot friendly. I would appreciate your honest opinion on it? Cheers G 👍

Been to the whifbitz shop they are not offering their own exhaust, just the rubbish sounding HKS systems.
where did you see this exhaust advertised? it looks and sounds good.

Great video, exhaust sounds good, and loving the tips. Can I ask how much it was fitted? and did you consider any other makes?👍
