    The CBE isn't what causes it to change, you need to replace the DP, then your ticking noise will change. The loudness of the ticking noise (my theory) is due to the stocks DP only having like 1/4 " clearance between the waste gate and a solid flange. It creates a "tick" before merging with the rest of the exhaust and flowing down the exhaust track. A bellmouth fixes this as the WG is now able to expel the gas down an empty tube, thus nothing to audibly "tick" against. The sound then changes to a fluttering sound.

    Royal purple is junk. Doesn't meet Subarus rating recommendations and can void your warranty.

    Synthetic is great stuff and last longer especially in CA climate, I find Mobil 1 5w30 (not the Supersyn) more than adequate and is available at Walmart $23 for 5 quarts.
