deleting catalytic converters

top end power takes a shit because you dont have backpressure anymore

 

Long enough piping and a muffler........backpressure is there.


For all the tree huggers...........yall ever see the crap coming out of diesel trucks....eighteen wheelers....now I can see some environmentalists complaining about that. I don't see our trucks or cars anywhere close.

 

I think Robby (tacomaforlife) did it to his truck, shoot him a pm will.

 

Jon..yeah......I did. Waiting for him to get back to me.

 

That's mostly unburned diesel. Diesel engines produce less CO and HC than a gas engine. But they produce a lot of NOx but within the last 2 years the EPA required them to have a special injection system that sprays a special fluid that breaks down that NOx

What my 3.4 sounds like on a single chamber and a track pipe instead of the second cat.

 

. and ^^^ that sounds pretty good. i have no muffler just cat and staight duals out and i love the sound on my truck. oh and i love how some people are all, "save the earth" dont pollute. lol. take a look at china's emmissions rating...

 

i say go for it. I have been thinking of doing it to my 2.7. let us know how it works out

 

Bad Idea, I did it to my 2.7 and got terrible gas mileage and lost power. Plus, it sounded like hell and I have a flo pro max muffler that sounds good. Hope this helps!

 

Wonder how it would sound with stock muffler?

 

Maybe not as loud, but still would sound bad imo. Plus, your still going to lose MPG and power which the 4 banger needs all it can get!

These are the numbers I got:

21 - 24 mpg city/hwy with the Cat

15 - 17 mpg city/hwy without the Cat

 

I did this to my 4.0 and I regret it.

 

I haz DTLT headers and Wicked Flow Exhaust, it does sound raspy when its cold after it warms up its fine. Low end feels aboot the same, and top end i can feel a bit moar power! Plus I have tw sicker, doug thorley sticker, and URD sticker so that equivalent to 26 hp, and i gain front pressure

 

Ever wonder why the Tacoma's don't have diesels in north america ever heard of ULSD that all the diesels are now burning it is an issue and it's being addressed VW sold no US diesels in 08 because they did not pass the 50 state emissions. Any new diesel is cleaner right now then any gas engine with out a cat including trucks.

 

Ok.......yay....newer diesel are pretty clean. Good to know.

 

still saying if people are worried about our trucks then why not China's coal plants? they are the worlds leader in emmissions anyways...

 

i love the environment and outdoors as most do. i hunt and fish every chance i get.....i plant trees/flowers....do alotta yard work........but i aint worrying about a tiny bit of emissions...........aint happening.

damn tree hugger hippies.
