Flowmaster 80 Series Cross Flow Mufflers

For true dual exhaust performance where only a single exhaust system will fit such as is commonly found in classic Camaros and Firebirds, the 80 Series Cross-Flow Muffler fits transversely behind the rear axle and in front of the fuel tank, the OE placement. With single or dual inlets, the 80 Series gives excellent ground clearance, aggressive tone and dual outlets to fit muscle cars requiring this specialized fitment. Constructed of 16-gauge aluminized steel and fully MIG-welded for maximum durability.

Flowmaster, Inc. (“Flowmaster”) extends the following limited warranty to the original purchaser of its mufflers, exhaust systems, pipes, exhaust tips, headers and other non-race accessories (hereafter “products”), excluding catalytic converters sold under the Flowmaster® brand.

Flowmaster warrants the products mentioned above against defects in materials and workmanship for the period set forth below, when they are owned by the original purchaser and remain installed on the vehicle on which they were originally installed. This warranty is void if the product was not installed properly on the vehicle, was installed on a vehicle for which it was not designed, or was removed from the vehicle on which it was originally installed and reinstalled on another vehicle. This warranty shall not apply to normal wear, cosmetic issues such as coatings and material discoloration, any product that was installed on a racing vehicle, installed improperly or contrary to Flowmaster instructions, altered, misused, repaired, damaged from an accident, collision, undercarriage road impact or debris, or willful or negligent act.

The warranty set forth herein for Flowmaster® stainless steel mufflers, stainless steel exhaust systems, stainless steel pipes and other stainless steel exhaust accessories (except exhaust tips) extends for a period of the life of the original vehicle the product was installed on. The warranty set forth herein for Flowmaster aluminized steel mufflers, aluminized steel exhaust systems, aluminized steel pipes, all exhaust tips and non-race exhaust accessories and commercial applications of aluminized steel products or stainless steel products extends for a period of three (3) years from the date of original purchase and the original vehicle it was installed on. The warranty set forth herein for Flowmaster exhaust headers extends for a period of one (1) year from the date of original purchase and the original vehicle it was installed on. Header warranty does not cover damages caused by exhaust insulating wrap, and is void if the product was installed on a new or rebuilt engine during the initial break-in period.

To make any claim under the terms of this limited warranty, the original purchaser MUST either return the product to the original retailer or directly to Flowmaster. If the original purchaser elects to return the product to Flowmaster directly, he or she must first contact Flowmaster and obtain a Returned Material Authorization (RMA) number. Once the RMA number is received, the original purchaser may return the product to Flowmaster® at 1500 Overland Court, Sacramento, CA 95691 (or such other address provided by Flowmaster) along with the RMA number and Proof of Purchase of the covered product. The Proof of Purchase must clearly show the place of purchase, purchase price, product purchased, and date of purchase. If upon inspection by Flowmaster the product is found to be defective in material or workmanship, Flowmaster shall at its option, either exchange the product for new product with the same part number or refund the original purchase price.

This warranty is not contingent upon the purchaser’s completion of the Warranty Registration Form found on the Flowmaster® website. If however the purchaser completes and submits that form at the time of purchase, Flowmaster will keep that form on file which may serve as an aid in determining warranty coverage in the event of the loss of the original purchase receipt.

Flowmaster’s liability is expressly limited to the replacement of the product or refund of the purchase price as described herein. Flowmaster® shall have no liability for the cost of installation or removal of the defective product, the cost of labor or any additional parts required to complete the installation of the replacement product, towing or transportation costs, or return shipping costs. In no event shall Flowmaster be liable for any direct, indirect, special, incidental or consequential losses and/or damages, including but not limited to interruption of business or loss of business or loss of profit or damage to related components resulting from the use of or inability to use the product, or any breach of warranty or any defect in the product, even if Flowmaster shall have been advised of the possibility of such potential losses or damages. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights. You may also have other rights which may vary from state to state.

The warranties set forth herein are exclusive and unless otherwise required by applicable law no other warranties are made by Flowmaster® or are authorized to be made with respect to the product.
