Helix

[UCWRX]

I just got a helix dp and have been trying to figure out what it connect to. Will it work with the stock cat-back on my 05 sti. What aftermarket cat-backs will work. Is there someplace which has allready covered this. Thanks.

It should, might need to change the flange on the DP or CBE. But any aftermarket CBE should bolt right up to it.

it has been cover several times before. like metioned above any cat back will work, What gasket should I use?
