    Overall Assessment

    Customers appreciate the product's perfect fit and quality materials. Some noted minor adjustments needed for proper installation, primarily related to the collector flange and end pipe. However, these issues don't compromise the product's overall functionality. In contrast to competitors, our product has been confirmed by customers to provide value through its robust construction and practical design. However, it's advised to equip replacement bolts for the installation process, emphasising the product's need for customization for optimal fit. This feature sets it apart in the market.

    Speedway was amazing, great customer service and fast shipping. As for this exhaust system the pipes itself fit right the the collector flange wouldn't fit over the expanded collector pipe and needed to be ground out to fit and also the collector end on the pipe had to much pipe flared out and wouldn't allow the collector bolts to pass through. One last thing with the supplied bolts and brackets as 2 lag bolts that is supposed to be used in the crossmember are for would not metal and I had to get replacement bolts.
