Hello Ryan,

The picture shown is the proto-type Helix cat-back on my car. Yes it did had some issue but that was well addressed and fixed when final production rolled out. No need to worry about fitment issues on this cat-back! Thanks!


NvsEVO/schleppy,

Thank you for the support! Greatly appreciated!

Just ordered a helix downpipe! How long is the $449 offer for the helix cat-bax w/ free test pipe going on for? Depending on how I like my new dp, (and how much $ I have left) I just might order the catback.

One question though, how much difference does the test pipe make compared to my stock cat?

 

Hello Johnnysixer,

I highly recommend using full 3" setup to compliment the 3" dp. There's no comparison between test pipe and stock cat in terms of performance.. The power gain from using test pipe can be immediately realized upon installation! instant 10-15whp!

As for the price goes, since you bought the DP from us, I can offer you complete cat-back at a good price! just let me know when you are ready!

Thanks

Hey Cal,

I want in on this deal if its is still going.

Hey there...I was interested in hearing the sound clip, but the link you provided does not seem to want to work. If there an alternate site i could look at to hear it. I was between the HKS catback and this...i really like the sound of the HKS, but would like to hear what the helix sounds like....it seems like a great system for a great price

 

Cal,

How do i place the order for this. Do i call you?

Thanks,
Luis

 

Sweet! Thanks Cal! Could we possibly arrange a deal on the helix cat-back w/ a 3in cat? I've already been pulled over w/ my stock exhaust.....don't wanna actually get a ticket for it.

 

Hello Luis,

Thank you for the order! Your package will go out today!

Thank you
