The Ultimate High Flow Cat Question!
Yeah here we go with another mod. Ive seen and read about a few for the 07 models (stillen, berk, crawford, etc.) but I wanna see what you guys think and have heard/seen/have. Trying to find a good HFC that wont drone and will make this Bassani scream. Reliability is a plus. Funds dont matter.
Go search google videos for bassani berk, bassani crawford etc. Try to find video/audio of your exhaust with each cat and see how each one sounds. I've never heard a bassani exhaust at all, so I have no personal opinion on this one.

I've had ceramic ultimate racing hfc and ran metallic Ultimate racing. Metallic HFC gave up with my SC setup, but i love their quality. I checked their website i don't think they have an 07 model. But You might want to check with adam@z1auto.

haha no i read it man. but you have a SC, im stock, and you didnt provide any info on these such as how they sound performance gains and such. I did email Ultimate Racing to see if they have an HR HFC available. oh and gogle search only provided bassani and berks which sound pretty damn good i might add

I'm quite satisfied with my berks... threw 1 CEL standard code, might have to get the non foulers.. probably won't happen unless you really push your car however.
I hear crawford makes some decent ones.

100 cell cat?

Ill be getting the 200 cell versions installed sometime in the next month. Had a couple on my old car and loved em.
They dont come with pipe work to bolt straight in however, so you would have to get them custom done.

i have berks which sound nice and have served me well for almost 2 years
however, im afraid they might be spent now.
I've started to hear slight slight metallic rattling noises, i think something may be up so I'll be checking them soon

damn they sound awesome! I think they will take the win if they have an HR version.
i kinda got rid of some....it was coming from where the x pipe connect to the cats.....maybe its just that i have NO CATS what so ever so i guess i have got to get used to the noise!!
got an email from Ultimate Racing today and unfortunately thay havent come up with an HR cat yet and the DE motors wont work properly. Oh well, Crawfords or Berks Crawfords or Berks Crawfords or Berks Crawfords or Berks hmmmmmmmmm or Test pipes?
