I honestly hate the sound of my exhaust. Around 2900rpm it starts to sound horrible, like when a semi truck hits the engine brake going down a hill. I always try to shift before it gets up there to avoid the embarassment of the noise.

 

Where did you pick up the kit?

 

From Downey:

You guys are pretty funny early in the morning.
My two cents: Pile, sounds like a nice system you've got. I agree with the customer service @ Downey. I personally have bought 2 Thorleys at the either the muffler shop or the Dyno shop and since they did the pipework behind the header they gave me a good price on the part.
In both situations a connector pipe had to be made from the header to the cat so I had to go into the shop anyways.
My truck sounds great and the throttle response is better. Not amazing but better.
To the guy that hates his sound and shifts early to avoid it, put your cat back in. I tried putting in a straight pipe, spent $$ to have one made with bolt on flanges and everything. Took it out 2 days later because it sounded so bad.
Hope this helps anybody interested.

I have a 2 1/2 in pipe the rest of the way back and a Bullet muffler

 

Oh yeah and whats with the ceramic coating? I've never even considered getting that because (1) the manifold doesn't come that way factory and (2) heat under the hood is never a problem.
I don't care how they look in 50,000 miles but if you do, keep your hands clean when you install them.
Don't think I paid more than $260 for my last one.

 

So ceramic is a big waste and doesn't keep excess heat out of the engine bay better than a plain corroding steel header? hmmmmmm.

 

Wow. Nice looking kit. I'll have to wait on that though since I don't have 800$ laying around for a header and exhaust kit.

 

Hmmm...thanks for the tip. I might give that a try. I've spent so much on the exhaust as it is I'd hate to put more into it, but the sound is so aweful I might have to.

 

hey guys im new here and i have a 4runner with a v6 with the 3.slow and i just blew the engine and im rebuliding it and want to get headers for it and i need some help pick ing the right set

 

Holy thread hijack.

Welcome to Yotatech!!!!

I don't know much about the 3.0, but this thread was mainly about the 22R-E. HOWEVER, if you use the search button at the top you'll probably find alot of answers for what you need.

My parents live in McKinelyville.

 

Really? Wow, that's great! I just had Dairy Queen! It was awesome!

 

You're mocking my post aren't you?

 

No.

 

Buzz Lightyear?

"You're mocking me aren't you?"

 

ehehhehehe

 

Doug Thorley is a TRI-Y design

Downey is a 4 into 1 design


Due to the typical design of most headers the engine compartment temp is lowered as well as dispersed over a greater area. I wouldn't route anything vulnerable over a coated or uncoated header.

My paint hasn't bubbled on my hood and my plug wires are happy.

Oh yeah, exhaust pipes rust and corrode from the inside out. Its mighty moist in there. I guess the coating could hide a pinhole a bit longer than an uncoated pipe would.

 

hey bigbluepile did you lose any low end torq with the 2 1/2 exhaust?

 

Hell, I dunno. I went from stock-rusting-fell-off-the-manifold exhaust to header and hiflow(whatever that means...) 2.5" piping. I pretty much improved everthing!!! So, yeah, it's better.

IIRC LC using a 2.25" cat back kit, but I went cheap(apparently...) and went with Downey's system. Honestly, if I get(and it WILL happen) another truck I'll go with a 2.25" exhaust just to see. These motors are not low rpm torque monsters anyways. I can TELL when the power band peaks. Maybe one day I'll put in an engbldr cam!!! lol!

Do I like what I have-Yes.
Does it sound good-Yes.
Does it intimidate Ricers-Oh yeah.
Does it perform-Yes.

 

thanks i think ima go with the downey header and a 2 1/2 exhaust. if i had to by another cam i dont think i would go back with and engbdr cam, i mean he has good products and he has good custimer service but the cam just wasent as radicle as i thought it was going to be.

 

Well, who knows, maybe the new exhaust will help out the cam.
