Typical cost $1,200 before anything else
Across the 0% window $80.00/mo 15 months, no interest

How we got that: $1,200 spread evenly across the 15-month introductory window on the Discover it® Cash Back. Checked · at the bank Carry a balance past the window and the standard APR applies to what is left.

A high-performance exhaust system changes how your car breathes, sounds, and feels on the throttle. You get a deeper tone, a bit more pep, and the satisfaction of a clean upgrade under the bumper. But running a modified car means paying for parts that rarely go on sale outside of major holiday weekends, when vendors finally drop their prices.

We look at holiday online sales because that is when you will find the softest pricing on stainless steel headers and cat-back kits. You want to line up your parts purchase when the discounts hit, and keep the installation cost separate from the hardware. A financing window helps you handle the upfront hardware cost without draining your checking account all at once.

Keep in mind that the intro window is a deadline, not free money. If you still carry a balance when the 15 months are up, interest kicks in on the remaining amount from day one.

The steps

  1. 01

    Hunt the holiday sales

    Wait for major online holiday events to order your kit. Exhaust parts are heavy and shipping eats margins, so look for retailers offering free freight alongside their holiday markdown.

  2. 02

    Line up your install shop

    Don't guess what installation will cost. Call a local specialty shop before you buy to get a firm quote on labor, rusted bolt extraction, and new gaskets so you aren't surprised.

  3. 03

    Use your card window

    You can use the Discover it® Cash Back card's 0% intro APR for 15 months on purchases and balance transfers to buy the hardware. Spreading that typical $1200 cost across the 15-month window means paying about $80.00 per month.

  4. 04

    Automate your monthly payment

    Set up auto-pay for your monthly share right away. Treating the payment like a fixed bill keeps you on track to clear the balance before the promo period ends.

  5. 05

    Save for the extras

    Set aside a little extra cash for unexpected hurdles like seized O2 sensors or extra hangers. Shops always find one stubborn bolt on an exhaust swap.

  6. 06

    Check the card terms before you commit

    Every figure we publish for the Discover it® Cash Back carries the date a person verified it against Discover and a link to where they checked. Intro windows and APRs change without notice, so confirm the current terms before applying.

Common questions

Will an aftermarket exhaust void my factory warranty?

By law, a dealer has to prove the aftermarket part caused a failure before they can deny warranty coverage. However, a loud cat-back kit might draw extra attention at the dealership, so know your local noise laws.

Should I install the exhaust myself?

If you have a driveway jack, jack stands, and a good set of penetrating oil, you can do it in a few hours. If the car has rusted underside bolts from winter salt, pay a shop to save yourself a headache.

Do I need a tune after getting a new exhaust?

Most cat-back systems do not require an engine tune because they sit after the factory catalytic converters. If you are changing headers or downpipes, you will likely need a tune to avoid a check engine light.

What is the difference between aluminized and stainless steel?

Aluminized steel is cheaper and fine for dry climates, but it will rust out eventually if you live where roads get salted. Stainless steel costs more upfront but easily outlives the car.
