My various Axleback exhaust review.

Sound is good. Mellow after warm and stays quiet until about 3500rpm and then noticeably louder. A bit of drone but way better than AAM short tails. This is a great axleback for the price and the best balance between stock and something like the short tails or a muffler delete.

I'll run this set up for a while. I want something that accentuates the VQ engine sound. I'll be adding test pipes or HFC's soon, but will be hanging onto my G37 muffler as I might end up doing test pipes or hfc's with resonator delete and G37 muffler with 370Z tips welded on and potentially add a Y-pipe.

I'm picky, and just can't get the exact exhaust note I want
