Description

Quick facts:

More power and better response

Expect a decrease in turbo lag with power and torque gains as high as 59 HP and 95 FT-LBS of torque over APR Stage I!

Full 76mm Race DP system

The APR system is a full Race DP upgrade as it replaces the kinked 60mm catalyst cross pipes and resonated midpipes with straight through, 76mm mandrel-bent tubing.

Port-matched investment-cast Race DP inlets

The factory inlets are restrictive. APR’s cast system allows for massive, port-matched inlets that smoothly neck down over a long distance. The result is improved flow, better response and more power.

Dual, high-flow catalysts

GESI’s encapsulated catalysts are known for their strength and performance. Expect lower emissions, reduced noise and less exhaust smell compared to catless setups, all without negatively impacting performance to over 1,000 HP. Furthermore, with the catalyst moved, expect a cooler engine bay!

T304 stainless steel construction

Premium grade T304 stainless steel resists corrosion and stands the test of time.

Argon back-purged TIG welding

Clean, strong and attractive welds both inside and outside the pipes.

OEM-style low-profile slip-on clamps

The APR slip-clamps are easy to use, resist leaks and pipe deformation better than swedged setup, are lower profile than vbands and flanges and don’t require replacement gaskets.

OEM-style internally-corrugated flex sections

APR’s flex sections are internally corrugated to increase flow and prevent failures common with braided flex sections.

Investment cast secondary oxygen sensor bungs

APR’s obsession to details resulted in investment cast oxygen sensor bungs that sit on top of the piping, preventing material from protruding into the exhaust stream, disrupting flow.

Compatible with the OEM catback exhaust

Bolt-on and go! The system is fully compatible with the factory catback exhaust.

Designed, assembled and quality controlled in-house

All critical aspects of the system are handled internally to ensure the highest quality fit and finish.

All hardware and instructions included

New OEM gaskets, oxygen sensor harnesses, clamps, brackets and install instructions are included to make the install as headache free as possible.

APR Stage II ECU Upgrade price waived

With every APR Race DP purchase comes a free upgrade to Stage II from Stage I, saving consumers hundreds of dollars!

Limited lifetime warranty

The best system on the market also carry the best warranty in the industry!
