5th Gen Y-Pipe?

[captainnemojr]

I just installed my new Borla exhaust last night, and was amazed at the craptastic stock y-pipe. I know it's the lowest part of the vehicle, but I didn't know that where the Y comes together, it's still 2 pipes squished into the bigger one. I should have taken a picture. You can see it right where the cat-back exhausts bolt on to the stock.

I saw where BFLAN had a custom Y-Pipe installed, but does anyone know if maybe URD or anyone else will be making one as well? My next project is to save up for some Doug Thorley headers, so all I'll lack is a Y-pipe for a complete exhaust system!

PICS Please!!!

:thanks:

I talked to URD about a Y pipe before I had mine done. They said they were unsure if the one they currently make would work or not. At the time they were not planning on selling one for the 5th but that was before Gadget bought a 5th and before the new supercharger.

I am sure they will sell one eventually but who knows how long that will be??????

I would just go have one made like I did. I think I payed around $250-$300 for the y pipe, and it turned out very nice. I also still have the old one, so when emissions time comes around I can just replace the headers and y pipe with the stock manifolds and stock y pipe

PICS Please!!!

:thanks:

I can snap a few pics for you tomorrow. Its nothing fancy, just eliminated the rear cats and is much higher than the stock y pipe.

Coming from high performance small block chevy's (LS6 and LS7) the Y-pipe we have is junk. I personally believe we are losing HP just from how small it is. The restriction it "appears" is horrible. I would like to just replace the Y-pipe with large piping and a smooth transistion, opposed to the small pipe that is used now. I still can't believe how it is from the factory, is could be choking the engine, maybe why we have hesitations in the first place.

You should call Toyota and let them know how bad their exhaust engineering "looks".

I seriously doubt that the y-pipe is creating more backpressure than the large number of cats on the exhaust. Plus, you have to remember that Toyota has to make some compromises to get acceptable tone and resonance for a majority of their customers. A majority of 4Runners are being driven by moms and dads, afterall, and a droning, rumbling exhaust would probably kill more sales because most people that want a loud, showy exhaust aren't in the market for a $35k SUV. With exhausts being an easy thing to change, it is smart for Toyota to make the OEM exhaust appeal to a majority of the buyers and let the guys here on T4R pick their own exhaust "flavor".

More importantly, how do you like the Borla?

If you could post your Credit Card number so I can use it for a long distance calls and a few classes for speaking Japanese I will do it.

I like the Borla exhaust. It's got a nice throaty rumble at start-up, idle, and acceleration. It's not a bad sound for a 6-cyl, and it quiets down at cruising speed. I like that it is stainless, and the install went pretty well. It is also lighter than stock.

You don't even need to lift the car to install it if you can fit under it. I had to cut out my old pipe like some others did. It comes in two pieces with a clamp. To install the new one, you just have to lower the spare tire to the ground, and you'll have enough room to maneuver the tailpipe piece into place.

As far as performance, I have no idea. The sound at full throttle gets drowned out by my intake, but I can still hear the low pitch of the exhaust rumble/vibrations. It's definitely unobtrusive.

I decided to go with Borla because I plan on eventually changing out the entire exhaust with stainless (headers, Y-pipe). Otherwise, I would have just added a muffler. The counties in Texas outside the major metropolitan areas do safety inspections only--meaning no emissions testing is required, so I don't really care about my cats as long as I get rid of that darn back pressure.

I bet a full exhaust system would unlock maybe 30-40+ horsepower? Gas mileage should be better too, assuming no heavy foot syndrome.

For $250-$300 I may just get a Y-pipe made. Gadget charges ~$450 for the Taco ones, so I bet a 4Runner would be in that ballpark. I can start saving up and just get the headers too, and then get the shop to install everything.
