Hey fellas, I went for a little thrash around last night in my 1zzfe rolla. The only mods of got are a 2-1/4 inch exhaust and a trd air filter. I started hereing a whistling/wheezing noise up past 4000RPM. I don't think i've heard it before, I'm not sure. Does anyone else's rolla do this or have they had this problem? I also reved out a couple times going down mitchells pass which is when I started hearing it. Cheers, Ben

Hey there, I'm new here but was wondering if this manifold actually went on and how well it went? cheers,
