BMW M3 & M4 F80, F82, F83 Cat Delete Downpipes
Our Price: $895.00 Exc GST

The 3.0 liter Twin Turbo I6 S55B30T0 engine in the BMW M3 & M5 (F80, F82, F83 platform) packs a powerful 425 BHP and 410ft/lbs of torqque. The most advanced M3 platform BMW has ever made. But with two huge catalyst bricks per exhaust bank, a lot of backpressure is created, increasing engine bay heat, restricting airflow and performance and limiting spool speed on the turbos. Particularly when applying ECU Tuning, the stock cats are very restrictive and an obstacle to gaining good power.

VelocityAP has designed a cat delete downpipe for the F80, F82 and F83 cars. Utilizing 304 Stainless throughout for supreme heat resistance and durability, minimal turbulence and restriction.

Removal of the stock catalysts dramatically improves the exhaust sound, letting the Inline 6 breathe.

These are a must for any big HP build. Pair with our ECU Tuning for maximum results.

The 3.0 liter Twin Turbo I6 S55B30T0 engine in the BMW M3 & M5 (F80, F82, F83 platform) packs a powerful 425 BHP and 410ft/lbs of torqque. The most advanced M3 platform BMW has ever made. However, as with most modern turbo engines it is capable of much, much more. BMW has limited output to allow for ever increasing performance variants in later model years.

VelocityAP's performance software builds from our experience with the 4.4L Turbo engines, offering seamless integration, improved power & throttle response throughout the RPM range. All without compromising factory driveability.

Removal of the stock catalysts or replacement with 200 cell sport cats allows further improvement in HP & Torque. See our downpipes for these vehicles for further info.

BMW M5 F10 & M6 F12 F13 200 Cell Sport Cat Downpipes
Our Price: $2,395.00 Exc GST

The 4.4 liter Twin Turbo V8 engine in the M5 and M6 packs a powerful 560-600 BHP depending on variant. The most powerful M5/M6 platform BMW has ever made. But with two huge catalyst bricks per exhaust bank, a lot of backpressure is created, increasing engine bay heat, restricting airflow and performance and limiting spool speed on the turbos. Particularly when applying ECU Tuning, the stock cats are very restrictive and an obstacle to gaining good power.

VelocityAP has designed an Ultra-High Temperature 200 Cell Catalyst downpipe for the F10, F12 and F13. Utilizing 304 Stainless throughout for supreme heat resistance and durability, minimal turbulence and restriction.

Replacing the stock catalysts dramatically improves the exhaust sound, letting the V8 breathe. It also prevents misfire codes which are common with some cat delete downpipes using large expansion chambers.

These are a must for any big HP build. Pair with our ECU Tuning for maximum results.
