URD has updated our Tacoma Cat-Back system, now called the Mark 4 version. We have redesigned the tail pipe section to better accommodate the larger spare tire of the 4×4 trucks while still fitting the rear sway bar and ground affects package of the XRunner. The system uses a very large muffler to tame the exhaust note when used with cat-less headers and Y pipes. It sounds wonderful no matter what the combination!!!
The New Mark 4 system now has our new anti-drone technology. This is a true resonating J tube that is tuned to cancel unwanted exhaust frequencies that contribute to exhaust drone while cruising. The exhaust goes from a nice high performance with a deep tone while accelerating hard to a very quiet purr sound while cruising. The best of both worlds.
URD 3″ stainless Cat-Back fits all access cab trucks and double cab short beds too. (not for double cab long beds)
Designed to maximize power from URD’s Supercharger Kit. Improves power and torque from a normally aspirated truck.
Kit includes:
- Made in USA
- True resonating J-Tube to eliminate drone at highway speeds.
- Use a large stainless muffler with an excellent performance tone. The muffler has an inner core made of 304 grade stainless and an outer shell of 409 stainless.
- Mandrel bent exhaust
- 3″ 304 stainless exhaust with polished tip
- Bolts up to OEM flanges
- Very simple installation with all needed hardware included
- Properly fits the XRunner ground affects package
If you are supercharging your 1GR Tacoma, this exhaust is a must have item.
URD’s 3″ Tacoma cat-back exhaust system is handmade in the USA, and it is made of quality, heavy gauge (wall thickness) 304 grade stainless steel. All bends are mandrel bent to ensure that the exhaust keeps its full 3″ diameter from the beginning to end so flow is maximized. The 304 grade stainless material will look great for many years and will outlast the truck its self.
This system installs to the stock mounting points and it bolts up to the stock Y pipe, URD Y pipe, or the Doug Thorley Y pipe. No cutting or welding is needed to install. Complete installation takes about 20 minutes.
When URD designed this Cat-Back system we had our own supercharger system in mind as well as other forced induction systems. We were concerned that the large 3″ diameter piping might be too much for normally aspirated combinations and might lose some low end power. We did some dyno tests and we were very pleased to see that there was no significant low end power penalty when installed on a normally aspirated engine. We were even more pleased to see the nice gains in the entire RPM range. So, for you normally aspirated folks, this system works great.
Note- Does not fit 2012 and earlier trucks.
