The MBRP XP Series 3″ Cat-Back, Turn Down, T409 exhaust adds performance and an aggressive “throaty” sound to your Tacoma.

The 3” diameter mandrel-bent pipes and high-flow muffler provide increased airflow over the stock 2” cat-back system for a small increase in horsepower and torque.

Installation Overview

Tools Needed for MBRP Aftermarket Exhaust Install

Allow the exhaust to cool down before you begin your work. The Install time is approximately 30-60 minutes. Eye protection is recommended.

Note: This install was done on a Tacoma with a relocated spare tire, 33-inch tires, and 2” rear lift. If you have a stock set up, you may need to consider the following points during step 2 of installation. This is just a guess, however, and may not be necessary. I personally haven’t worked with exhaust removal on a stock truck.

Tools & Materials

Tips For Install

  • If your truck has a spare tire in the stock position under the bed it might need to be removed temporarily.
  • If the truck is stock ride height you may also need to jack up the rear of the truck on the frame allowing the axle to droop. Making more space to clear the exhaust pipe between the axle and the underside of the truck bed.
  • If the exhaust system is caught on the axle and you’re unable to jack up the rear: Cut the pipe behind the muffler and it will drop out easily in two pieces.

Step 1. Disconnect Stock System

Start by removing the bolts (14mm) from the rear flange of the Y-pipe located just past the passenger side front door.

Keep the bolts, you will reuse them later.

Next, remove the hangers from the rubber isolators starting from the flange.

You may want to spray a little WD40 on the rubber to get them to slide on the hangers. Use channel locks or exhaust hanger removal pliers to push the hangers out.

If your truck is NOT a double cab long bed (DCLB) then you will need to trim the front pipe.

Cutting MBRP Exhaust

Measure 20 1/8” inches from the flange and mark with a sharpie.

Do this all around the pipe to keep your cut straight.
