And it couldn't have been easier! The old system came off with a single screwdriver. The new system fit perfectly and was fastened with two bolts that you could finger-tighten. Took 5 minutes total to do.........NOT!

Actually, it was a little more involved. I'd bought the TRD dual-outlet, cat-back system months ago from a place in NH. They were running some sort of special for $250 (pick-up only) and I typed in the comment box to ship to my address in Colorado. The ad said it was for 2003-2005 4Runners. Well, this huge box showed up and I got the system for $250 total. When I opened the box and read the instructions, it mentioned only 2003-2004, said nothing about fitting 2005 and nothing about fitting models with XREAS. Having read the numerous posts about different systems, what they'll fit, what mods are needed, losing vs. keeping the spare, it was clear that there were no clear answers if the thing would fit (I've got a 2005 Ltd with XREAS). I suspected it wouldn't, so it sat in the box for several months. Even thought about just putting it up for sale and buying a system that I knew for sure would fit.

I finished my training in Colorado and returned to Missouri. We've had some nice Fall days, so thought I'd install that exhaust system. Got the 4Runner up on some ramps in the rear. Took the exhaust loose from the front (easy), then tried to get the main section loose from the piece that goes up and over the axle to the outlet. For what ever reason, the factory had welded the nuts on the bolts and it was impossible to get loose. Couldn't get a hacksaw on them, the nut-splitter was in my tool chest in storage, couldn't even get them off with the air hammer and chisel. Ended up passing the point of no return by taking my cutting torch and cutting the pipe after it exited the large muffler. No going back now! Got the old system off and went to work putting the new on in its place.

First hint this wasn't going to be easy....the front section seemed about three inches too long because some of the hangers didn't quite line up. Some did, some kinda did, one didn't at all. Got that section in place and went to put the passenger side y-pipe in place. Kinda lined up, but seemed about three inches from mating well with the flange of the front section. Eyeball-fit the driver side and it looked like it would clear the spare. Got to the point where I realized I couldn't make any more progress, so called a custom muffler place that installs Magnaflows, etc. Took it to the shop, put it on the lift and told the guy that it looked like it would fit if about 3 inches were cut from the front section between the little resonator and the large muffler.

He cut the system, took out a little section, and rewelded. Also repositioned the front hanger to work with the factory mount. Mounted the Y-section over the axle (the passenger side outlet matched the factory hanger well). It cleared the spare well and the driver's side outlet did, too, with just a little tweaking. But the hanger on the driver's side didn't match with the extra mounting piece that came with the system, so he repositioned the hanger on the pipe to work. He kept the vehicle overnight and I picked it up this AM. The dual outlets look nice and he did a great job with the little tweaks and changes to get it to fit. I'll take pics later, but will take a little while to get them developed (yeah, I still shoot film. If you come over, I'll show you my new 8-track player, too!).

The guy charged $150 for the installation. Seems money well spent. Still got my spare, doesn't hang down, all the hangers are positioned correctly. It was done by a guy named Gene at Seeburg mufflers in Springfield, MO. I'm super picky about some things and he did a very nice, clean installation.

It definitely changed the sound of the vehicle. At idle, you can't hear anything, but the low growl picks up early. A little drone at about 30 mph. Haven't really had it out on the highway yet. I'm sure the sound will change as it goes through some heating/cool down cycles.

Overall, very pleased. The guys thought it looked like a Borla system (I've heard they make the TRD systems). So, with the killer deal on the $250 system + $150 for the custom install = $400 for a nice system. Took a little longer than expected and a few detours.

what, no pictures??!:mad: :p

You still paid much less than what the TRD exhaust goes for normally. I almost bought that same exhaust when it was posted a few months ago but I already had the Magnaflow installed.

you'll love it with an intake.


I see you've got an '05 Ltd. Does it have the XREAS system? Did your cat-back TRD system fit without any mods? Mine was part # PT901-17400-19. Are they the same part number? My guess is that the XREAS option is maybe the difference.

Looking back at my original post when I ran across that killer deal, it was waaay back in Dec '05. Nothing like dragging around something in a huge freakin' box for nearly a year!

I've got a K&N filter installed, but didn't know they made an intake for the newer Ltds. Is that the new system I've seen some post about? Seems like somebody was letting K&N use their vehicle as the development vehicle, but I thought that was for an '06. Including part numbers really helps, so thanks.

I wonder how the intake compares to a K&N filter in the factory air-box? I like K&N stuff (got it on all my vehicles and cycles), but I installed the K&N filter only about two months ago and a new intake would scrap it. Suppose I could sell it on the forum.

Yeah, it worked out to still be a great deal. I just like to do things myself since I'm picky about how they're done, but I'd reached a point where I couldn't do anymore and Gene did do a great job.

It was so odd that the system was so cheap. And I didn't get charged anything for shipping. That box was huge and heavy, sent all the way from New Hampshire to Colorado.

Got a roll of pics shot today, gotta get 'em over to Wally World for developing.
 
i do have the same part # exhaust. i do not have x-reas, but for some reason the system doesn't fit with my spare tire on. i also had to have the guy at the muffler shop modify it so that the hangers would fit.

you got a great deal compared to what i paid for it. $750 for the system and $50 to install.

The K&N intake is the new one that came out a couple of months ago. there are 2 kits, 1 chrome and 1 plastic and i believe they fit both the 05 and 06. i have the plastic one.

That's the odd thing about these exhaust systems--nobody knows what will and what won't fit. It's almost like you just have to install it to see. I've always heard that the addition of XREAS was the problem with fitment around the spare, but mine fit nicely around the spare. I've even seen some TRD 4Runner systems (different part number, but no picture to see what's different) that specifically mentioned it wouldn't work with the XREAS system--didn't say specifically what "wouldn't work", e.g., hits the spare, doesn't match with the hangers, hits the pipes from the XREAS, etc.

The driver side hanger on the pipe did have to be modified just a little to match with the hanger that mounts to the frame rail. The passenger side fit pretty much as usual. The front section was the problem (about three inches too long). It includes a small resonator just downstream from the junction of the left and right cylinder pipes (which, incidentally, the one coming from the driver's side of the engine has a section flattened somewhat so that it didn't hang down too low). Seems like it would introduce some resistance, less of a free-flow system, but that's how it is.

Looking at the pics in the instruction guide (which was for 2003-2004), it looks like my spare is a little farther forward than the one pictured. Before putting on the front section, I was convinced that the driver's side pipe was going to be the problem. Instead it was the front section being too long.

Did yours smell like hot brakes for a while? Mine has a very distinctive smell, like hot brakes, after driving and if you get out of the car while it's running. It's not the brakes, that's for sure. I figure these new exhaust systems have a smell for a bit, but hoping it'll go away after some more miles. It's not a sulfery, rotten egg smell that apparently has been the subject of a TSB (I never experienced that with my old system, either).
 
Post those pictures whenever you get a chance...I've been considering that kit for mine.

Just FYI, etom and I have been kind of guinea pigs for that K&N intake. If you saw the thread, I posted those pics on my '05 Limited V8. I'm sure he would agree, the kit is great and would probably make an awesome addition to your exhaust.

Pics are going to Wally World today for developing, take a few days. I checked out those pics of the K&N intake. Looks really nice. I'm a big fan of K&N stuff. I'm still curious how what the flow advantage of the pure intake vs a K&N flat panel filter in the stock are box is like.

Was looking at the pics in the installation guide for that exhaust and the Y-pipe on mine hangs down (to about the bottom of the differential--and no more) while the pic in the guide shows it a fair amount higher (probably 2-3 inches). Also the spare in the pics in the guide looks like it's farther back towards the hitch. Mine is closer to the axle and there's a suspension rod that traverses just behind the differential. Oddly, the driver's side fit with just a little adjustment around the spare (that bottom of that pipe is just about even with the bottom of the spare).
 
As far as airflow, there is a definite advantage of the K&N intake over the replacement filter. The replacement filters do little to improve airflow if the airbox itself is restrictive. K&N boasts 12.3 HP with the new intake. As I mentioned in the other thread, the intake will help your performance...but you have to be careful not to stomp on the pedal everytime (Gas mileage!)
