EDELBROCK CAT-BACK EXHAUST SYSTEM

For 2000-2006 Toyota Tundra 3.7L & 4.7L V8, 2WD & 4WD

Catalog #5708

INSTALLATION INSTRUCTIONS

Please study these instructions carefully before installing your new Edelbrock Cat-Back Exhaust System. If you have any

questions, please contact our Technical Hotline at: 1-800-416-8628 , 7am - 5pm, Monday-Friday, Pacific Standard

Time or e-mail us at [email protected].

Suggested Tools for Installation:

❑3/8" ratchet set and metric sockets ❑9/16” and 15mm wrench ❑Hacksaw

❑Jack and jackstands ❑Liquid penetrant and rubber lubricant

NOTE BEFORE YOU START:

This Edelbrock cat-back system comes with three different I-pipes. This is because some Tundras (between 2000-2006)

use three catalytic converters. Others use 2 catalytic converters and a resonator. If your vehicle came from the factory

with 3 catalytic converters, you will use I-pipe #25-3269 behind the third catalytic converter. If your vehicle came from

the factory with 2 catalytic converters and a resonator, you have the choice of either retaining the resonator for a more

melow exhaust tone, or eliminating the resonator which will give you a more aggressive exhaust tone. See appropriate

steps below.

DISASSEMBLY

Vehicles Equipped with 3 O.E. Catalytic Converters:

1. Remove the V-band clamp behind the rear most

catalytic converter.

2. Remove the stock hanger bars from their isolators

behind the third catalytic converter and remove the

O.E. exhaust system from the vehicle.

3. Install I-pipe #25-3269 behind the rear most

catalytic converter

(See Fig. 1).

Vehicles Equipped with 2 O.E. Catalytic Converters

& A Resonator:

1. If you are retaining your O.E., resonator, cut the

factory I-pipe 10” from the back of the O.E.

resonator. If you want to eliminate the O.E.

resonator, cut the factory I-pipe right where it enters

the O.E. resonator.

IMPORTANT NOTE:

Proper installation is the responsibility of the installer. Improper installation will void warranty and may

result in poor performance and engine or vehicle damage.

INSTALLATION INSTRUCTIONS

IMPORTANT NOTES:

•Support your vehicle with proper jackstands or ramps rated for the total vehicle weight. Place stands so that the rear

axle is allowed to hang free for easy system removal.

•These cat-back systems are engineered to fit stock catalytic converters or equivalent replacements. If you original

system has been modified, Edelbrock will not warranty fit or performance.

2. Remove the stock hanger bars from their isolators

behind the resonator and remove the O.E. exhaust

system from the vehicle.

end of I-pipe, #25-3248 and install over cut end of

resonator pipe, slip hanger into rubber isolator. I-

pipe #25-3248 must slide into resonator pipe a

minimum of 2”.

If not using original resonator, use 2-1/2” band

clamp on end of I-pipe #25-3247 and install over cut

end of Y-pipe. I-pipe #25-3247 must slide onto Y-

pipe a minimum of 2”. Cut I-pipe #25-3248 on

reduced end back 3-3/8” so to remove reduced end,

and deburr. Place 3” band clamp on front I-pipe.

Install rear I-pipe #25-3248 into front I-pipe, engage

hanger in rubber isolator.
