    Recommend seller. Items as described. Quality item, and the item was a good value for the price. Item was delivered in excellent condition. Shipping time was excessive. This would be eBay’s fault, not the seller. Item shipped out June 16 from USA, and delivered July 8 in Canada. eBay definitely needs to overhaul their international shipping to provide better service for the amount they charge.

    Great system for the price. Quick on shipping. Was shipped in 2 boxes….one arrived a couple of days earlier than expected and the other arrived a couple of days later than expected. It was all good though. Seller responded promptly to my question. Will purchase again!

    I Love speedway , though this time they upset me a little .. waiting for wheels finally called and they tell me on backorder and 6 months before they will be shipped , they should have contacted me , or better yet , don't advertise things you don't have , but this is the first problem in well over 20 years . they are still on my top for sellers.

    Flowmaster 50 series big block

    It sounds good but on a 6.0 chevy with no catalytic converters you get a high pitched cackle at certain rpms.
