Limited Product Warranty, Policy and Procedure

All ISR Performance products sold are warranted for a period of 1 year on "Hard Parts" and 6 months on "Moving Parts"  from the original date of purchase. No warranty claim will be valid without authentic, dated proof of purchase. This Warranty does not cover parts or labor used in the installation and/or removal of any products. Any product which has been modified from its original state or defaced by the end user would not be eligible for warranty coverage.

This warranty is to the original retail purchaser and none other and is available directly from ISR Performance and not through any point of distribution or purchase.

Customers who utilize "Flame" or "Barble" tunes would automatically forfeit any warranty to exhaust components such as headers, catalysts, y-pipes, and exhaust systems. These "tunes" subject exhaust components to DRASTICALLY higher temperature and pressures than they are intended to operate in and will cause catastrophic failure of exhaust components with extended use. 

If a defect is suspected, the retail purchaser must contact ISR Performance directly to discuss the problem, possible solutions and obtain a Return Merchandise Authorization (RMA), if deemed necessary by the company. All returns must be shipped freight pre-paid to the company and with valid RMA before they will be processed.

ISR Performance will examine any product returned with proper authorization to determine if the failure resulted from a defect or from abuse, improper installation, misapplication or alteration. ISR Performance will then, at its sole discretion return, repair or replace the product.

ISR Performance Parts MAP Pricing Guide

ISR Performance Parts actively supports the advertising and promotion of its products by its domestic dealer network, and in an effort to strengthen its dealer network it has decided to institute a MAP pricing policy. Effective May 1st 2015 all dealers will be required to meet ISR Performance NA MAP pricing requirements.

MAP policy guidelines

MAP Pricing applies only to advertised prices and does not apply to the retail price at which ISR Performance products are actually sold, nor does it prohibit advertised prices that are higher than ISR Performance MAP pricing.

MAP Pricing on ISR Performance Parts products is fixed at 10% off of MSRP. Current MSRP pricing can be found on .

Advertised prices of products may not appear in any media for less than MAP pricing, this includes print catalogs, television, radio, signage/flyers, posters, coupons, or any internet and electronic media, including websites, e-mail newsletters, forums, or auction sites. Websites featuring ‘click for price’ or automated pricing e-mails, ‘in-cart’ specials, or other forms of communication initiated by the reseller will constitute a MAP violation if lower than MAP pricing.

Retailers must sell ISR products in their original packaging. Retailers cannot change, re-label, adulterate, or otherwise alter ISR products and packaging.

Selling open box items is permitted, however, “Open Box”, “Display Model”, “Demo” products must be clearly marked as such by the retailer listing them for sale. Only 1 listing of an “Open Box”, “Display Model”, etc. product is permitted at a time, and only quantity 1 is authorized to be listed. Listings must be clearly labeled as “Open Box”, “Display Model”, etc, and photos of the actual product must be displayed in the listing showing its condition.

If it is determined a vendor is listing new product as “Open Box”, “Display Model”, etc. and selling multiples of the same item to circumvent MAP pricing their account will be subject to immediate cancellation or discount tier reduction.   

In addition, customers of ISR Performance NA are responsible to distribute this policy, or otherwise notify their customers of the terms of this policy. Distributors selling ISR Performance products to violators of this policy will suffer the same consequences as outlined below. ISR Performance will pursue all violations, and it is in your best interest to ensure your pricing is within MAP pricing terms, as well as any resellers you may distribute to.

Authorized sale/promotion policy for Authorized Dealers.

During each calendar year (January 1 to December 31) each authorized dealer is allowed 2 specific sales or promotions pending ISR Performance approval.
