    There is a step in the instruction to save the 14mm bolt to attach the pipe to the tranny housing but no fitting on the pipe.
    Did I do something wrong or just a goofy instruction step. It is solidly attached to the bell housing and bottom mount. Just wondering.
    No shaking, wobbling or weird noises from the install.

    We see boost creep problems on dyno quite often with the catless downpipes. Especially with the dense air we've had lately. Since there's only so much adjusted wastegate values can do to prevent boost creep; I recommend catted downpipes to almost everyone.

    Easy install and a sweet burble. Now if I could figure out why one muffler is slightly lower. Not loud and Ricey at all.
