Hymee Exhaust installation + Dyno results!!

(cross posting from the .au site )
--

Hey guys

Got the Hymee installed today and man I am VERY impressed. Hymee, without a doubt this is one beautifully manufactured exhaust..well done!

Sounds great (even @ idle!!!), looks stunning and really enhances the rotary experience.

I had my car dyno'ed before and after - very impressed about the performance gain, didnt expect THAT much..installation was pretty standard except we used a new midpipe.



EDIT: Dyno + installation was done @ Power Tune, Fairfield.

Were both those dynos done on the same day by the same operator?? That improvement is an impossible one. I have a Hymee exhaust BTW.

Hymee wouldn't believe those figures either, IMO.

Yup, done about 4 hours apart on the same day, same operator.

did you know which gear it was done at and was the dyno loading altered?

4 hours apart can still play a huge difference

Easy....if you change the midpipe at the same time, like kunz did. You don't have to undo the Jesus clamp....

Funny, I got the midpipe replaced with a 2.5, with the stock cat still in place and it feels the same but only less puffy. Although my last run with an EVO 9 was quite impressive at higher speeds.

Well come on Kunz - is there a reason for the coyness?

Spill, unless it's not legal, in which case your silence will be interpreted as confirmation.
