Vous trouvez que votre C8 ne sonne pas autant exotique qu’elle en a l’air? C’est probablement la modification que vous cherchez.

Nos downpipes transforment complètement le caractère sonore de la C8 : beaucoup plus présente, agressive et surtout beaucoup plus exotique, avec une sonorité qui rappelle davantage ce qu’on s’attend à entendre d’une Ferrari/Lambo.

Et surtout, pas besoin de dépenser 4-5-6k$ sur un cat-back complet pour avoir une vraie différence.

Disponibles en High Flow Cat ou Catless, ils sont probablement l’un des meilleurs bang for your buck pour complètement changer le son et le caractère de votre C8.

Pourquoi nos downpipes?

* Jusqu’à +30 HP / +30 lb-ft

* Environ 17 lb plus légers que les pièces OEM

* Une sonorité beaucoup plus agressive et exotique

* Meilleur flow et meilleure réponse

* Stainless 304 conçu pour durer et résister à la corrosion

* Fabrication TIG entièrement faite à la main à Laval

* Garantie à vie sur les soudures

* Installation bolt-on

* Tout le hardware inclus

Fitment Corvette C8 2020–2025 : Stingray, Z51, Z06 et E-Ray.

Installation professionnelle disponible chez ATL Fabrication : 685$.

Catless :1 400$

High Flow Cat : 2 400$

Shipping disponible partout au Québec et ailleurs pour ceux qui ne sont pas dans la région de Montréal.

On voulait surtout offrir un produit à la hauteur d’une Corvette C8 : beau, durable, performant et entièrement fabriqué à la main ici à Laval.

Notre objectif est simple : offrir l’un des meilleurs rapports qualité/prix sur le marché, sans faire aucun compromis sur la qualité des matériaux, la fabrication ou la finition.

Un produit haut de gamme, à un prix qui reste accessible.

Et pour ceux qui n’ont pas de C8, ATL Fabrication ne fait pas seulement ces downpipes. On se spécialise également en fabrication automobile sur mesure pour tous types de véhicules : systèmes d’échappement, intercooler piping, modifications et projets complètement custom en stainless, aluminium, titanium et plus.

Vous avez un projet ou quelque chose que vous ne trouvez tout simplement pas off the shelf? On peut probablement vous le fabriquer.

Built the right way.

2018 Porsche 911 Turbo S — Custom Charge Pipes

A cool collaboration with the guys over at Blitzkrieg Tuning on this 991.2 Stage 2 Turbo S making 635whp

The factory charge pipes were replaced with a full custom 2.5” aluminum setup, eliminating the smaller sections and restrictions found in the OEM piping while getting rid of the factory plastic construction.

The biggest challenge? We built the entire setup remotely, without ever having the car at our shop.

Using the original pipes as references, everything was replicated and fabricated directly on the table. On a setup like this, being a few millimeters off can be the difference between a perfect fit and something that simply doesn’t work.

Both charge pipes were fully fabricated in aluminum, TIG welded freehand no positioner, and finished with bead-rolled ends to properly retain the Vibrant Performance couplers under boost.

Setup:
• Full 2.5” aluminum construction
• TIG welded
• Bead-rolled ends
• Vibrant Performance couplers & clamps
• Fabricated remotely from the OEM piping
• Built for a 635whp Stage 2 Turbo S

No car. No jig. Just measurements, fabrication, and trusting the process.

1969 Pontiac Grand Prix Full Custom Exhaust

A full exhaust built from the headers back, with a few challenges along the way.

The existing headers ended with a 2.25” outlet, while the client wanted a full 3” system. Instead of using a conventional reducer, we formed our own short transition to step directly from 2.25” to 3”, keeping the transition compact and clean.

From there, we built the entire system around the chassis with a custom H-pipe to keep a deeper, more aggressive old-school tone, paired with Series 58 mufflers from Cortek Exhaust

At the rear, everything had to route over the axle while maintaining enough clearance through the full suspension/axle travel. The client also wanted absolutely no visible exhaust tips, so the system finishes with hidden turndowns for a subtle exterior look.

Setup:
• Custom 2.25” → 3” header transitions
• Full dual 3” exhaust
• 304 stainless steel
• Custom H-pipe
• Cortek Exhaust Series 58 mufflers
• Hidden turndown exhaust tips
• Sectioned 2-piece design for easy removal
• Fully TIG welded
• Lifetime warranty welds

Classic look. Old-school tone. Built to fit the car properly

Une journée comme une autre chez ATL

08/03/2026

This Infiniti G37S came to us with a turbo kit designed for a G37X.

Although the two cars look similar, their front subframes are different. That difference meant the downpipes had no clearance and there was simply no way to make the turbo kit fit by modifying the manifolds or exhaust piping.

Instead, we redesigned the front subframe to replicate the engine mount geometry of a G37X, creating new engine mount locations while retaining the G37S subframe.

This allowed the turbo kit to fit exactly as intended, without compromising the design of the kit itself

Built the right way.

A custom valved axle-back for this C7 Corvette.

It might look simple, but centering four exhaust tips perfectly is one of the most demanding parts of a build like this.

With so much open space around the four tips, even the smallest misalignment stands out immediately.

The kind of detail most people never notice… until it’s wrong.

Built the right way.
