Just did this same delete on my 4 runner. On 100 degree day in stop and go traffic it vapor locked from exhaust pipe heat by the fuel line. Rerouted the fuel line to outside of the frame and solved the problem.
I was worried mine would do the same. I bought some header wrap to insulate the new exhaust pipe but it never gave me trouble. Maybe I haven't spent enough time in stand still traffic. Is yours a stick or auto?
Mine's no slow go any more. Did 4 things. 1. Gutted the Cat. Converter 2. Egr delete 3. Cross over pipe delete. 4. Advanced the timing . 18.5 mpg highway 16 city.
U said in your video that your passenger cross over side pipe section was turned 90 degree downward. My question: The triangular flange is not an equalaral triangle. The triagular flange can only fit one way. (1) did u have to cut the passenger side pipe at the flange and welded it to have it pointe downward?? (2) did you use the driver side pipe section immediately after the passenger trigular flange first because the driver side pipe section is longer than that on the passenger side.? (3) did you weld the driverside pipe section to the passegner flange first and then weld the driver pipe section to the passenger side pipe sectin after that ? Thank you
I was thinking about just running two separate pipes from the manifold straight back to the bumper or joining them further back and then into a single muffler and then out the rear of the truck. Any suggestions or thoughts on how that might work?
nice welding beads. Which welding method (Acetylene/oxygen gas or MIG or tIG?) did you use? was there any issue welding sheet metal to the cast iron cross over ?

Granted that 21 mpg was not loaded down with gear, loaded down I would see 18-19-20, never really got better than 16-17 around town.
@@HectorTorres-fi2lh Main thing is getting rid of the stock crossover that merges at the driver side exhaust manifold, it makes that #6 cylinder run hotter that all the others, hence why the gasket usually blows on the driver side of the engine if you use the stock head gaskets. You can get metal head gaskets, but as long as your there you have the opportunity to put headers on, or at least improve upon the head gasket situation. Back pressure is never good as rpms rise little bit down low helps low end torque, but heat is the enemy to certain degree with aluminum heads and steel block the two materials expand at different rates contributing to the head gasket situation.
When it comes time to do a clutch I'll cut it and weld on flanges or V-band clamps. That pipe running under the transmission was a 5 minute way to finish it so I could test drive it.
The heat from pipe has not been an issue. I did buy some header wrap because I was worried about it but after installing the pipe it seemed like there's plenty of clearance so I didn't bother wrapping it.
@@XathosPvP i didn't get to hear it run with a stock crossover. Its an original catalytic converter with a Flowmaster muffler. I imagine there's no change in sound. I'm thinking cylinder #6 is running at much cooler temperatures though.
@@bigblockbumpside2296 runs n drives just fine. I imagine at wide open throttle at 6k rpm its probably lacking its maximum potential but ill never rev it that high. Its very back yard and low budget . Its probably all in my head but this is the torqiest gen two 4runner I've ever driven (low end power)
@@hotrod7181 I have the very same set up as yours gut the converter removed all Egr system got rid of all the unessary vacuum lines bumped the timing up couple degrees my little 3vze is a torque monster with stock manifolds
I bought the 4runner with no engine so have no reference to compare it to. After reading about this engine i thought It would be silly to not do a crossover. Most of my worries was in using a 3.4 bottom end but that turned out good. Is yours running hot?
Can some one explain me why he did that please? I have one 1995 and its like cow very slow and I would like to give it more power, it's that help? Thanks to all 😁
Yes.. it has passed 2 "California" smog test since. I was concerned that because it was 400cc larger it may run slightly lean and fail NOx, but it passed with fantastic #s, even with an original cat with 270k miles. Its now my sons daily driver.
They weren't powerful , economical , or reliable. I believe using multi-layer-steel head gasket instead of the composite material along with crossover delete will at least make it reliable. This is the second one I've done and so far so good.

Would it be a good idea to install some kind of disassembly joint on the pipe? Seems like it would be very difficult to remove, when you have to.
For sure that would be best for servicing the clutch or other related maintenance. If and when that day comes i will add flanges to make life easier.
Good Idea, looks like I'm doing some pipe fabrication tomorrow, after I get the new head gaskets on 👍
Thanks. I just realized this mod is more difficult on trucks with auto transmission. Hopefully yours is manual.

Is back pressure a good or bad thing to have? Anything to do with torque performance?

That spider is spooky
So you telling me that when you wanna do a clutch replacement you gotta cut the pipe and reweld it

The heat from the exhaust pipe not affecting the transmission? How close does the pipe end up the being to the starter? It hasn't been affected?
The heat from pipe has not been an issue. I did buy some header wrap because I was worried about it but after installing the pipe it seemed like there's plenty of clearance so I didn't bother wrapping it.
@@bensfixitpage341any updates on transmission? Changed oil at all?
I am researching how to dual pipe and straight pipe my emissions exempt model...
What year is your Toyota? What state do you live in?
I want to straight pipe mines too , where do I fit to see a video?
Good idea, but you dead headed that exhaust when you brought it over to the other side. Try sweeping it into the other pipe.
Agreed. I was in a rush to get it rolling. Maybe I'll build a nice y-pipe when some free time comes my way.
@@bensfixitpage341 How does it sound now?

Nice two pipe solution fight against the blown gaskets on your 2 Runner (4x2) and a big spider too ha ha.
Its a bit ugly but it works great
Good idea you still need some back back pressure to keep your low end torque you wouldn’t believe how many people don’t understand that
What would you do differently?

Very hard to get more power out these engines. It is what it is. Get a 3.4 if you want a little more power
Does it pass smog?
Yes.. it has passed 2 "California" smog test since. I was concerned that because it was 400cc larger it may run slightly lean and fail NOx, but it passed with fantastic #s, even with an original cat with 270k miles. Its now my sons daily driver.
This exhaust system makes no sense!
Its an odd one. The driver side manifold receives all of the passenger side exhaust then exits through a single pipe.
If that isnt the stupidest exhaust pipe design ive ever seen lol why would the legendary toyota do such a thing haha
I guess one the Toyota engineers ran the #s and found a way to make a slow engine even slower
To make the transmission more serviceable
Buena idea, mala ejecución
Hola not nice
So this engine would have been fine if not for that stupid crossover pipe. Who knew?
