IWSTI Addict since: Jun 2004 Trader Rating: (14)  | Don't bother replacing your uppipe, the stock pipe is already catless. From what I have heard, the Helix downpipe is top notch, it's very common around here. I personally have an APS TBE, which is extremely well-made, but it only works as a full turbo back system and it's not cheap. |

| Grassroots STI Racer | If you want to upgrade prior to the turbo, go with a header with integrated uppipe. Gruppe-s just started a thread on nasioc a few days ago where they did a before/after only of their header/uppipe. No power loss anywhere on the band with increased midrange and top-end. Greddy Evo 2 is IMO the best quiet exhaust you can get. All the others seem to have a restrictive design. This ad is not endorsed by this member. Please register or login to hide this ad. |
