DMM MOTORSPORTS

The best DMM Motorsports parts in this collection are the DC Sports pieces for the Subaru WRX and WRX STI: a cold air intake and a single canister cat-back exhaust for the 2015-2021 cars, muffler deletes in polished, black, and burnt tip finishes, a rear strut bar, and a blue pitch stop mount, plus a short ram intake for the 2002-2007 WRX and WRX STI. Check your year and model before ordering.

This is a mixed bolt-on collection covering three jobs. Intakes change how the engine draws air, exhaust pieces from the muffler delete to the full cat-back change flow and sound at the back of the car, and the strut bar and pitch stop mount stiffen the chassis and drivetrain. Start with the part that matches your goal: most of this range centers on the 2015-2021 WRX and WRX STI, led by the DC Sports cold air intake for the 2015-2021 WRX.

DC Sports is the product brand behind every listing here, sold in this DMM Motorsports collection. Its range in this catalog is focused and Subaru-heavy: two intake styles split by generation, three muffler delete tip finishes for the same 2015-2021 application, a single canister cat-back exhaust in polished finish, and chassis and mount hardware including a rear strut bar also listed for the FR-S and BRZ. That makes this a simple one-brand shortlist for WRX bolt-ons.

Invidia is the exhaust specialist shoppers most often cross-shop for the same 2015-2021 WRX and WRX STI, with a much deeper cat-back and downpipe catalog. Compare Invidia when you want more tip, piping, and sound options than the single DC Sports cat-back here, and browse the wider strut bars range for other chassis options.

GrimmSpeed is the Subaru-focused engineering brand in this conversation, known for intakes, intercooler parts, and engine-bay hardware built around WRX and WRX STI applications. It is the natural comparison for the intake and pitch stop side of this collection.

K&N Engineering is the intake-focused alternative, centered on air intake systems and filtration for a wide range of applications. Our comparison of cat-back exhausts for the 2015 and newer WRX and WRX STI helps weigh the exhaust choices before you buy.

What is the difference between the muffler delete and the cat-back here?

The muffler deletes replace the rear muffler section and come in polished, black, and burnt tip finishes for the 2015-2021 WRX and WRX STI, including the polished tip version. The single canister cat-back is a fuller exhaust system in a polished finish for the same application.

Which intake fits my WRX?

The cold air intake is listed for the 2015-2021 WRX, while the short ram intake is listed for the 2002-2007 WRX and WRX STI. Match the intake to your generation, and check the product guidance on tuning before driving after an intake change.

What does the pitch stop mount do?

The pitch stop mount limits engine and drivetrain pitching movement under acceleration and shifting. The DC Sports version here is blue and listed for the 2002-2025 WRX and WRX STI, so confirm your year before ordering.

Are these parts bolt-on?

These are application-specific bolt-on style parts, but difficulty varies between an intake, an exhaust section, and chassis hardware. Check product details, and use a professional for anything you cannot fit safely.
