HKS down pipe will fit.
Anything below 3" in diameter its good.

 

So the Espelir 3 inch downpipe will not fit?? I was under the impression that it will

 

Well i got all my mods on my 05 now, and i must say the helix dp i had pn my 03 fix perfectly on my 05. It cleared the Tc by like a hair. I have no rattling at all which i did have a lot of on my 03. Now i dont have to buy an new dp

 

wow, finally someone that has a helix on an 05. Thanks for chiming in!

 

mine does the same thing... you figure out why it does that yet?

 

I was told when I bought the helix that I got a v2 helix DP and NO, it will not fit without rubbing on the t-case and the center cross member area. It rubbed on my '03 on the cross member and I had to take a hammer to the cross member to knock it up a bit. Traded in my '03 for an '05 and thought I could just get away with doing the same thing....nope! It rubbed on my t-case, so I got rid of it.

 

My helix dp cleared the TC by like a hair , lol!! I do hear it rattle once in a while but its not against the tc. I need to make some adjustments
