The best P&L Motorsports parts for a Subaru WRX or WRX STI are its fabricated exhaust pieces — like the GESI-catted J-pipe — and its engine-builder hardware. P&L is a Subaru-focused performance parts manufacturer whose catalog reads like a shop manual: J-pipes that unlock turbo response, plus the fasteners, flanges, and fittings that make an EJ build go together right. If you're bolting real power onto a Subaru, start here.
What P&L Motorsports Builds
P&L's exhaust hardware targets the restrictions Subaru left in the factory downpipe. The J-pipe — the FA20DIT engine's name for the downpipe — is the first exhaust component off the turbo, and a well-built catted unit like P&L's GESI-catted J-pipe for the 22-26 WRX with a manual transmission frees up spool and midrange without the smell and check-engine drama of a catless pipe. P&L also machines the small parts other brands skip: CNC up-pipe flanges, master bolt kits for EJ builds, crank surface locks, and stainless steel brake line kits.
These are parts for builders and tuners, not cosmetic dress-up. If your build sheet has a turbo upgrade or a built short block, P&L likely has the hardware that holds it together — check your year and model, especially on transmission-specific parts.
The Brands in This Corner of the Catalog
P&L Motorsports is the house name on everything in this collection: a Subaru-dedicated performance parts maker known for fabricated exhaust components and precision engine hardware. Its parts skew toward serious builds — the kind of catalog where a Diamond Claw crank surface lock sits next to a stainless brake line kit — rather than bolt-on appearance pieces. That builder-first focus is why P&L hardware shows up in shops that build EJ and FA engines for a living.
GrimmSpeed is a Subaru-focused performance brand whose intakes, intercoolers, and exhaust parts pair naturally with P&L hardware in a full build. Browse the GrimmSpeed collection for complementary bolt-ons.
Perrin Performance is another Subaru-dedicated brand whose parts catalog — from drivetrain bushings to turbo kits — overlaps the same builds that P&L hardware serves. See the Perrin collection for more Subaru-focused upgrades.
Build out the rest of your setup with our performance intercoolers, cold air intakes, and performance engine mounts.

Frequently Asked Questions
What is a J-pipe?
On the FA20DIT engine in the 2015+ WRX, the J-pipe is what Subaru calls the downpipe — the first exhaust section off the turbo. An aftermarket J-pipe reduces backpressure right at the turbo for faster spool and more midrange torque.
Do I need a tune with a J-pipe or downpipe?
Yes. Changing the downpipe alters boost and fueling characteristics, so a proper tune is required to run it safely and actually gain power. Budget for tuning alongside the hardware.
Why choose a GESI-catted pipe over catless?
A high-flow GESI catalytic converter keeps exhaust smell down, avoids most emissions headaches, and still flows far better than the factory cat — the best balance for a street-driven car.
Will P&L parts fit my Subaru?
Many P&L parts are application-specific — transmission, engine code, and generation all matter. Check your year and model against the product's fitment details before ordering.
