  1. Awesome quality exhaust from what I can tell. Packaged well, arrived safely and in a reasonable amount of time. I absolutely love what it does for the look of my bike. Sounds great too! One of the more affordable options for exhaust when you factor in shipping cost to Canada, at least from what I could find. Seller was also excellent! Great communication and very proactive about offering assistance if needed.

  2. Outstanding seller with a great track record. The E3 plugs are an incredible value for the price. The quality was factory new. And the appearance of the packaging was in factory boxes within a shipping box. I am a repeat customer. As this seller has always had the E3 plugs I need in the correct quantities. I cannot recommend this seller more highly

  3. Actually....the wheel was not what I expected going from the description & communication to the Vendor was made prior to shipping. The Vendor advised me that it had to be attempted for delivery & rejected in order for the refund process to be initiated. Once the item was returned & received back by the Vendor, they refunded my funds as paid.
