Is helix coming out with a newer version? the old ones seems to be discontinued.. even though you can still get one. Helix is cheaper and prettier, but crawford seems to last longer..

 

Gruppe-S told me Helix no longer makes their cats due to low demand.

I had a set of these on my car for almost a year before the pass. side pipe cracked along the weld at the bottom of the cat. They performed well and made a very noticeable performance gain, but I've taken them off the car as I'm sick of dealing with all these exhaust problems.

Not to hijack this thread, but I may put these up for sale for cheap since the one cat needs to be welded up, the other is perfectly fine.

 

I am trashing a set of Helix cats for cracking reasons as well. I can't see what the difference between Crawford and Kinetix is, so I am going with the less expensive Kinetix cats.

 

do kinetix cats long? who's got the cheapest price?

 

go to www.kinetixracing.com

$369.99 for a set of quality cats from a reputable company

cant beat that

 

i guess there's no demand for helix - places have been out of stock on them for like over a year now....back in feb. 05 they were suppsoed to be making some new dna version 2 model, but it's been well over a year and......nothing.

 

you cant go wrong with Crawford products. I love mine..

 

My Helix have lasted and held up perfectly with my OEM exhaust manifolds and Injen exhaust. I got mine as soon as they were available, but it seems like you have answered your quesiton since they are no longer readily available. Just go with the Crawford. No matter what cats you have there is a chance of them cracking if your exhaust is not able to flex enough where it needs to.

 

I found them on ebay from my-liquidator. They state to be a sister company of Kinetix. I ended up getting mine this way for $355 shipped to my door. Since they are related companies you get the latest product and all warranties are honored.

 

great... I just ordered them for $413.. otd....

 

wait a minute.. I just checked the ebay site and those are the older ones. check out the kinetix site and make a comparison.. the new ones look a lot better.

isnt hi flow and resonated test pipe different?

 

nevermind.. those are cats that you're talking about.. I've gotten the TP ^ yeah they are. those cats are emisiion legal here in cali.. the tp aren't..

 

tat's test pipes vs cats there

fyi, even though u could pick up cats cheaper on flea-bay, i wouldn't - you have no idea if yo're getting an old inventory product or not (and the older cats are known for definite cracking, which has been addressed in newer models)

 

The vendor I mentioned and bought from is part of Kinetix. The cats I bought are the latest improved design. Find my-liquidator and read the description. The return address on the package is from Kinetix themselves so their claim is true.

 

I'm selling a set of used UTR metal HFC's $400. No complaints, awesome quality.
Reason - lease is up and time to get a new car!
