Exhaust system?

Does amyone know of a good exhaust system that will make the v-6 sound more throaty

 

There are a bunch out there; Borla, Flowmaster, TRD, etc. Search around. I don't know of any "bad" brands. I personally am leaning towards the Borla, but the TRD is covered under warranty.

 

jhodge...mind if i ask how much you nabbed that up for? liking the sound of that one too (based on their website)

 

Ditto on the Magnaflow.
Check here for prices on a Cat Back system, also mention that your a member of a truck forum, they'll nock off another 10%.

I have TRD on mine, and I really like the tone. Add TRD cai and use 93 Octane, and you will notice a performance difference!

 

Does your Tacoma engine have such a high compression ratio that 93 octane gas would actually help performance?

 

The V6 has 10:1. The manual states that "premium" fuel will provide the best
performance. That along with the TRD exhaust and CAI really improved the performance of mine!

 

Hoofhearted:
My '07 V6 owners manual does not say anything about using 93 octane, only regular gas. What year is your Taco ???

 

The manual does state that 91 was used for all tests.

 

Mine is an `05.
Cut and pasted from page 382 in my manual:
Fuel type:
2TR- FE engine—
Unleaded gasoline, Octane Rating 87
(Research Octane Number 91) or
higher
1GR- FE engine—
Unleaded gasoline, Octane Rating 87
(Research Octane Number91) or higher.
For improved vehicle performance,
the use of premium unleaded gasoline
with an Octane Rating of 91 (Research
Octane Number 96) or higher is recommended.
Hoof?

 

On page 276 of the 2007 Owners Manual, it says "Select Octane Rating of 87 or higher. Use of unleaded gasoline with an Octane Rating lower than 87 may result in engine knocking. Persistant knocking can lead to engine damage."

Just make sure you know the difference between Octane Rating and "Research Octane Number". Octane Rating of 87 = Research Octane Number 91.

Sounds like they revised the Owners Manual since 2005.

 

This may explain the ongoing debate as to which Octane Rating to use:

1GR-FE 4.0L V6 from a 2007 Toyota Tacoma. The 1GR-FE is the 4.0L version. Bore is 94 mm and stroke is 95 mm. Output is 236 hp (183 kW) at 5200 rpm with 266 lb-ft (382 Nm) of torque at 4000 rpm on 87 octane, and 239 hp at 5200 rpm with 278 lb-ft at 3700 rpm on 91 octane. This engine features Toyota's single VVT-i, variable valve timing, system and a compression ratio of 10.0:1. Inside, the 1GR uses a taper-squish combustion chamber design with matching pistons to improve anti-knocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamese-type intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls. This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. With these special thin liners it is impossible to bore the block. In the event of cylinder wall damage (scoring, deep protrusions, etc), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines. For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are such 2 passages for each bank for a total of 4. This reduces cylinder hot-spotting and keeps combustion chamber temperatures more uniform.

Some applications:

2003 Toyota 4Runner
2003 Toyota Land Cruiser (Europe)
2005 Toyota Tacoma
2005 Toyota Tundra
2005 Toyota Fortuner (Middle East)
2007 Toyota FJ Cruiser
2007 Toyota Tacoma

 

No that is what my 2006 Operators Manual says.
I have not seen a differance between 87 and 91 or 93.
No ethanol.
This taco is never going to see 5200 RPM.
So, over 87 is just a waste of resources.

 

i got mine for $150.... 40 series...including labor and exhaust tip

 

I had a Magnaflow. Thought it was too loud. Sold it. Put back on my original cat-back. Discovered it was now too quiet. So I went and bought another MagnaFlow cat-back. Now it sounds good... or it did... or it does again.
