TRD Exhaust Installation w/ pics

I somewhat recently did the TRD exhaust install on my access cab. There were no threads with pics when I searched, so I decided for future reference I would put some up. Now I know 95% of members on here will laugh at this because it is so easy but I prefer pictures of a procedure in addition to a write-up. Many new users who are debating buying this exhaust and installing it themselves should review the pictures and make their decision. Numerous threads and posts say it is super easy (which it is) but what is easy to a mechanic is not easy to a desk clerk.

I will say this, it took me an hour because I took my time, double checked things, took out my spare tire, and tried to avoid damaging the hangers. No lift was needed, and the only thing I used was the cold air intake box to let the exhaust sit on when I was installing it. Front refers to engine/cab, back refers to rear of the truck/bed.

To start, I used the write-up from the user "Se7en".
His thread can be found here:

Tools are :14mm socket, wrench, dish soap, new exhaust gasket and something to rest the exhaust on so it doesn't drop to the floor. I have a 4x4 so no lift needed but you do need to drop the spare. That allows you to actually sit under the bed to help work the angles to get the exhaust out.

Always confirm part numbers with your dealership.

PT910-89060 TRD Single Outlet Cat-Back Exhaust System for Double Cab Long Bed only.

PT910-89061 TRD Single Outlet Cat-Back Exhaust System for Tacoma double cab short bed, and Tacoma access cabs, not available for regular cabs.

Part numbers I found online of the STOCK setup:




1. Use a rag or cloth to wrap the tip of your exhaust so when it shifts and moves it won't scratch your paint. Leave the cardboard on the tip of the new exhaust until you are completely finished.





Look at all the room once the spare is down. Definitely helpful.


2. Use dish soap and massage the rubber hangers with it where the exhaust and frame are inserted into them. I found WD-40 was less effective. Now these rubber hangers are irritating, and some are easier to come off with the exhaust, and some are easier to leave on the truck. Doesn't matter as long as you install the new exhaust in the reverse order.

Pointing to one of the hangers with the tip of the WD-40. I switched halfway through to dish soap.


3. Measure under your exhaust and find something to support the exhaust once bolts are removed. I used my CAI box on its side. Worked fine.




4. Next I got my 14mm socket and wrench. I used my 1/2 inch torque wrench as it was the biggest one I could find. The two bolts are installed with loctite so you really have to put pressure on the wrench to crack them loose. Once I did this I noticed a quick cracking sound and dust like material fall which was likely the loctite disintegrating. Take both spring bolts off and put them somewhere safe for later.






5. At this point make sure you have the exhaust supported on the front end. Start manipulating the rubber hangers moving them back and forth over the hanger pins to let the dish soap do its magic.



6.Once you removed all the hangers (whether remaining on the truck or the exhaust), the exhaust will be supported by you on one end and the support on the other. Rotate the exhaust in order to get it over the rear axle. Be aware of the brake line and take tremendous care not to damage anything. The exhaust is heavy enough and has a natural curvature which makes it difficult to balance. These pictures may not be clear, but I was resting it NEXT TO, but NOT ON the cables. Pull the exhaust towards the back of the truck until you can angle it properly. Lower the support at the front of the exhaust and then slide it out going under the engine bay. Once removed put it to the side.



Emphasis on this picture is that there is absolutely no pressure or pulling on the cable. The exhaust is resting adjacent to it, I had to do this to take the picture.


Note the strategically placed shovel. Due to difficulty with the front end of the exhaust digging into the floor, I needed a "1 inch lift".
Also in the pic, front end now is down, moving it under the engine bay.


7.Now, reverse your steps, starting with the front edge of the exhaust under the engine bay, sliding the rear of the exhaust up over the axle, then twisting and turning until the catback is past it and can be rotated properly. Place your front part of the exhaust on the support and start placing the exhaust back in the rubber hangers. This is much easier than the removal process, so don't worry. Start with the rear hangers and work your way forward.




8. Make sure the holes line up, then insert and tighten the two spring bolts. Keep turning until it's tight. 33ft lbs torque, minimum spring measurement 40.5 mm (1.594 in.) if less than this, replace.




9. Remove the tip cover, make sure you don't have any packing material in the tip of the exhaust. Clean the exhaust tip and do a quick inspection to make sure everything is attached and looks good. These pics are for reference as some people have had the tips slightly bent.




10. Start it up and see how you did.
This video was my attempt at before and after (also had the intake on) but you really can't tell the difference until the very end of the video when it is near idle. More of a rumble.

Great writeup! Don't ya just love the exhaust note now? Sounds so much meaner.

I was going to install it myself, however the dealer threw it into the deal (including installation) so there wasn't a point in doing so.

Hopefully TRD comes out with an exhaust for the new 4Runner, I will be installing that one myself (if they ever do!)

 

I personally notice the sound change at idle, and like it. Not too loud but better than stock. Over 1800 RPM the cold air intake really enhances the sound. I did a before and after intake on the driveway just for comparison. No sound difference below 1800 though. I'm going to add the CAI before after pics as soon as I can find them.

 

Had this on for awhile, thought I would add my observations...
It sounds louder in warmer weather. As the months have gone
on, it has a deeper tone to it. Not sure why but it is clearly
a different sound now, subtle but deeper.
Don't regret getting it at all.

 

thanks for the update, I've been on the fence about getting this, might just have to, did you notice any gains in mpg or throttle response? I dont expect much but an improvement over stock would be a added bonus.

 

Mine sounds louder in warmer weather also. I had my catback on for about two weeks so far and the sound does seem to be slightly deeper than when I first put it on. That would be sweet if it got even deeper over the next few months

 

How hard was it to get the stock exhaust out from under the truck and the new one in with the truck on the ground?

 

Honestly it was simple, as I said you need to remove the spare tire. Then life is easy.

I have a 4x4 sport though, that might make a difference in ground height.

 

Well that is an interesting point you bring up. I have the air intake
and exhaust. Initially I thought there was a throttle response. I have
since driven a sport without the upgrades and honestly I don't notice
a difference. I got it for the sound anyway....

MPG I am not sure

 

Thanks for the write up and pics. Going to install mine this weekend and this will help.

 

Good pics and writeup for anyone doing an exhaust install. I love my trd exhaust too. Great sound!!

 

Just installed and now I am getting a slight shutter or rattling metal noise at takeoff.

Checked everything and everything seems tight... it is dark outside and I can't get into my garage for better light until tomorrow.

Any ideas?

 

Nice write up man! I think I made a mistake by buying a 2 chamber flowmaster cuz its a bit loud and droney. I think ill take a vid/pic too cuz I picked the WRONG tailpipe as well ...thought it was cool at first but now Im starting to think about changing mines.

 

In addition to my earlier post, I realized that I should have replaced the gasket .

I have an exhaust leak where the TRD exhaust meets the y-pipe. Leaking from the bottom and seems to be the cause of the slight rattle/shudder at takeoff.

Planning on picking up an exhaust gasket today and replacing it, hopefully that makes the noise go away.

 

Wow. You cannot imagine how much time I spent looking for that information and it was right here this whole time. I searched high and low for those specs that I remember seeing but couldn't remember where I saw them.

That's the info I needed to find before I did this, I just couldn't find it for some reason. Right under my nose maybe?

 

Thanks for the contribution, I added this to the original post in case people aren't reading all the way down the thread. Credit to you of course for the find.

 

Just found this thread. Yeah, for anyone thinking of getting this exhaust, do not and I mean DO NOT pay anyone to do this, this is one of the easiest jobs you can do on the truck, especialy on a 4x4. Took me about 45 mins, only because I took a smoke break after fighting with the damn hangers. Thats probably the hardest part of the whole job.

Thanks for the write up OP, hopefully this will encourage people to do it themselves.

 

Great write up! I followed it to the letter and the install was smooth as can be! Sounds great! Now, I just have to figure out what to do with my stock exhaust!

 

I gave it away to a TW member from clarksburg

There is not much of a market for them, I had a
scrapyard that would have paid money but the
effort to take it there was too much.

 

Thanks for the write up, it's always a pleasure to go on TW! We find everything and anything!!
