Just wanted to briefly share a few sound clips from before and after installation of the Z1 high flow cats for anyone considering this option.

Installation was incredibly difficult after a handful of Canadian winters which include salted roads. Even with all the proper tools and years working on cars I had to have them professionally installed. Original cats had to be torched out. Took 3 guys over 4 hours to get them out while I watched, they even stayed late on a Friday, felt so bad I came back with a case of beer.

Overall I'm very happy with them. Any questions please feel free to ask.

Before:

After:

Apologies for the second video, very windy. Will try to take a better one when it settles down.

 

Good stuff bro, glad u liked it after all !
Thx for sharing

 

Sounds good man cant wait to put mine on in 4 days !!

 

Video doesn't do it justice, you're going to be very happy!

Good luck with installation, hope Massachusetts doesn't salt their roads! Haha.

 

You make me missed my tanabe

 

Oh they are I'm not even attempting this lol

 

Still absolutely loving these. The sound is getting better as they break in, have about 200km on them now.

Threw a code today, looks like I've got an excuse to get Uprev now, haha.

Here's another video for everyone, unfortunately it's windy yet again and you can't hear the nice crackle and pop when you left off the gas.

 

That I didn't want to see, O2 code? I cant have that I have uprev but I can not shut the sensors off! Wont pass emissions.

Oh wait I think the 08's are different ? Do you have the extended O2 bung ?
