Dirtco's 1999 4Runner Build

trying to watch these videos! I'm so used to instant gratification these days and not even my universities network can grant me this. I cant wait to see them!
 
Well, the stock rock anchor of a muffler had to go. I have only taken it on one real rock crawling trip and I managed to drag the muffler several times. It really needed to be replaced with something smaller. While I liked how quiet the stock muffler was, it could be a little more aggressive sounding. I’ve had vehicles with loud exhaust systems and that’s not what I wanted; I wanted the smallest muffler that I could find, that was somewhat quiet, while adding an aggressive note.

I looked at several mufflers (Magnaflow, Borla, Flowmaster, etc.), but I chose the Flowmaster for several reasons. First, the size was just right and second; I’ve had a Flowmaster in the past and I was very happy with the fully welded steel construction. I picked the Delta Flow 50 series (Part number 942452), hoping it would not be too loud.

During the install, notice the size difference

After I first cut the stock tail pipe off, the exhaust aimed right at the P/S rear brake drum. I didn’t like this, and I felt that it was making extra condensation inside the brake drum on cold days. I was going to reroute the entire tailpipe but instead I added a turn down to redirect the flow, it was less work and does pretty much the same thing. I used a small section of a junk crossover pipe that was on an E-350 van I worked on.

How's it sound?

It sounds good!:D It was a little loud at first, but once I got used to it I'm happy. It has a nice aggressive tone at idle that gets louder as I accelerate, but once I get on the highway and hold a steady RPM the note decreases and it's only a little louder than stock.

I still need to take some pictures/video of the LED lights in action, so I'll try to get a sound clip or two of the muffler at the same time.

Ok sounds good thanks!
 
Stock reverse lights just don’t cut it when you need to back down a trail in the dark. I’ve always had an extra reverse light on my rigs, pointed straight back and on an extra switch. This time I wanted to do things a little different; I really wanted the lights aimed at where the edge of the trail would be and I wanted them to come on with the reverse lights so I don’t have to think about turning them on.

It took a while to find a place to mount the lights where they would shine the way I want, but I found a spot and I’m happy with the light pattern. I still need to wire the lights; I’m going to wire them to a relay and have the stock reverse lights trigger it but I want to wire my rock lights and a couple goodies for the trailer at the same time.

(Excuse the cell phone pictures, I forgot my camera)

Lights installed. They are just some cheap Walmart lights, but they should do the trick (they will only be on when I’m in reverse).

Testing the light pattern. I might pull them in towards the tires more, we’ll see once I get it on the trail.

I also removed the lower Toyota and old dealership emblem from the tailgate, they have been driving me crazy since I bought it!

And after, much better!

Had the Flowmaster Delta 50 on my last 3.4L, definitely a good choice. Mellow deep sound, and as you mentioned much more slim than the stock!
 
you know Fightman likes it when he posts it Twice :) (kidding)

but practical addition/mods dirtco! good job
 
Exhaust work... Nice. Backup lights... sweet. Removed emblems... had to be done, definite improvement.

So when is it this summer that you're planning the NM trip? :biggrin2:
 
Looking good man! Again....nice additions to a classy trail rig! :)

Thanks guys! I really feel it's the small details that make a rig your own. :D

I was a little worried at first; but your right, it has a mellow deep sound that goes away when you hit the highway. I like it!

Thanks man! I need to finish the trailer and apply for a title, I also need to upgrade to the Tundra brakes (I've been looking through your write up which is Awesome!), and take it on a shake down run or two.

I really don't have a time frame, but when I do I'll let both you and Ripcord know (it's going to be a while). I would love to get together and check out both of your rigs! I would also like to get some input from you on places to go, if you have some idea's. I'll let you know when I get the trailer wrapped up and get closer to an actual date.
 
Dirtco, would you happen to know if the 40 series sounds similar to the 50 series?

I might have the opportunity to buy a 40 series from a buddy....and was wondering what IT sounds like???

The 40 Series is a lot louder. I had one on the old green 4Runner and I would not run one again unless it was on a muscle car or a buggy. It's just too loud for daily driving in my opinion, it also resonates pretty bad on the highway. Hope that helps, I'm sure there's some videos on Youtube that might help you make your choice.
 
I'm going to copy and paste this from the trailer build because it directly correlates with the 4Runner. As the trailer gets closer to completion I might do this a couple times. I've been building the 4Runner and trailer so they share certain responsibilities and pretty much act as a "Team". You might ask, "Why don't you have a spare tire?"

The full build thread can be found here: http://www.yotatech.com/f88/my-camping-trailer-project-219053/

"I’ve also decided that I’m changing the wheels. The whole point of having 35’s on the trailer is so I can run one (or two) on the 4Runner in an emergency. Since the new 4Runner doesn’t have a spare, and I have no intensions of running one; this is important. The first problem is that 15” wheels will not clear the front brakes on a Limited 4Runner, especially once I upgrade to the Tundra calipers and rotors. The second problem is that the 2” backspace wheels I had on the Turbo 4Runner will tear the rear fender flares off the new 4Runner the first time I hit a bump. I’m not going to buy two new 35x12.20x17 MTR’s with 17” wheels, so there’s not much I can do about the first problem, but by changing the backspace of the wheels I could run them on the back of the 4Runner if I need to (If I get a front flat I’ll have to swap a rear tire to the front, then use a trailer tire). I needed a wheel with 3.5” of backspace; the Mickey Thompson Classic Lock had that, and also looked very close to the Trail Ready beadlock wheels I have on the 4Runner.

(Knock on Wood!) I’ve only had two flat’s my entire wheeling life, and both of those were rear tires that I lost the bead. I now have beadlocks, and I also have OBA with multiple plug kits. The chances of me needing to rob the trailer tires are slim, but I still like the fact that I can if I need to. I also don’t want to ditch the trailer out in the middle of nowhere, so I’m going to install the stock spare tire from the 4Runner under the trailer (that’s all that will fit) and use it as an “Emergency Donut” to at least get the trailer to a paved road. (Knock on wood again, just for the hell of it!)"
