Product Description

For off road use only (see note at bottom of page).

For years, it has been a common belief that all catalytic converters place a choke-hold on performance. In 1993, Random Technology disproved that theory with the introduction of Super High Flow catalytic converters. This design enables virtually any vehicle with a properly tuned engine to meet emissions standards with little, if any power loss (compared to an exhaust with no catalytic converter).

In fact, Random Technology catalytic converters actually have a higher flow capacity than most mufflers. This direct fit, bolt-in replacement for the stock catalytic converter on 3.8-liter vehicles has a 3 inch inlet and 2-1/2 inch outlet. It flows 438 cfm compared to 267 cfm for the stock converter at a test pressure of 28 inches of water. That's a 47% increase in flow! Add up to 8HP to the wheels with this converter! The added benefit of this direct fit, bolt on replacement is the inclusion of the U-Bend replacement and the enlarged downpipe. The U-Bend replacement does include the O2 bung for mounting the O2 sensor.

Independent testing by engine builders, racers, and automotive magazines has repeatedly proven the superiority of the Random Technology Super High Flow design.

NOTE: Compatible with W-body vehicles with 3.8 liter 3800 Series II / III engines only. The converter package includes hardware to mount the front section, but you will re-use your stock bolts and gasket in the rear.

2004-2008 Grand Prix Owners: A O2 Sensor extension harness required for 2004-2008 Grand Prix owners (excludes GXP). Please select the harness from the options below only if you own a 2004-2008 Grand Prix (excluding the GXP).

I just ordered this converter for my 04 grand prix. Overall, I was very pleased with a noticeable difference from startup and idle. Sounds good even with stock exhaust. A little more midrange torque and lower idling RPMS. Installation was simple. Installing this converter was considerably easier than removing the oem. Good part, now i need an exhaust :).

I have a 2003 Supercharged Monte Carlo SS and this item was a huge improvement. I loved the deep throttle sound it gave and you could really feel the extra torque that it gave. 5 Stars all across the board.

I have a Grand Prix GT and installed this product along with PFYC's SLP cat-back exhaust system. Deleting the u-bend and adding a bigger downpipe, as well as a more free flowing cat made quite a difference for a N/A car. Installation was very simple and only took about 30 minutes or less to the the old downpipe and cat out and put the new one in on a lift. I highly recommend this product to anyone who wants a better performing exhaust system, while still staying legal.
