Wow. Glad I cancelled my order for them.

 

bump..... is the new version out yet? i want to get these and wanted to know if they re out yet

 

bump for the same ?

 

any new updates??

 

Sorry I sold the car, but I would recommend the Crawford hi-flows =)

 

BUMP for updates - I just ordeded mine.

 

Still no dynos?

 

any updates with the slimmer Helix hi-flow cats?

 

Are they even out? Any pics of what they looked like? I just switched over to crawford cats from RT cats and wanted to see what these looked like...

 

are the new slimmer Helix cats out yet?

how does Helix compare to the Crawford cats?

 

I purchased the helix HFC's a while back but never installed them due to the fact that they hit the floorpan. So instead, I went with UTR's new Metal HFC's, picked them up during their recent sale. These fit fine, no hitting of the floorpan and they come with a support bracket. Quality is nice and butt dyno says there's some gain.

 

do you have a pic of them?....hows the sound of these UTR's?

 

yea i have the same question as well

 

Let me get this straight: Helix recommended you either dent the car, or dent the high-flow cat itself? That's kinda fugly. Denting your cat is one huge step closer to knocking loose the internals. Once the internals get loose, you'll experience lots of annoying rattling noises, and it might clog up your exhaust altogether.

I've heard a lot about Helix's bad fitment issues. Check out any other car forums, such as www.evolutionm.com, and you'll see what I mean. This seems to be yet another example. As for the new re-design they are supposedly coming out with, it's supposed to have smaller cats? Note that the smaller the cat, the less chance you have of actually passing smog! In fact, most of these aftermarket "high-flow cats" are not enough to pass smog here in CA. Chances are, you'll have to swap on your entire stock setup to pass anyways.
