i got me a flowmaster 40 put on yesterday with a 3inch powdercoated tip. anywayz its really quite. and it pisses me off. i think the reason it quite is the tailpipe from the muffle rback is just 2inch. is this the reason? also.. any of you guys with a 22re have gutted cat converters? ive had a few people tell me for some reason you cant do it to yotas. cuz if you can do.. im doin it. thankye fellers

 

You should have done 2.25" Pipe all the way back.. FYI

Either your Cat is plugged, OR they put the wrong muffler on, cause those are LOUD. I say chop it all off cat included and put a 12" Glasspack on it with a dump under the bed or side exhaust.. Punch out your cat and put it back on or replace it with a "test pipe" Emissions are retarded anyway.

 

i have a 2.25" from the y pipe to my muffler then i dynomax turbo with a 3" coming out of it. i would recomend just losing the cat all together ive had 4 yotas and never ran a cat on any of them. it frees up the flow and makes it sound better just be aware that running without a cat is illegal in most places

 

They are hard to punch out compared to the two others I have done. I did one on a Geo Metro that came out very easy. The one on my '88 p/u took at least 10 minutes of pounding with a 1" steel rod and a 3 lbs sledge. I'll have to get a new one when I'm due for a smog check.

 

i would go with 2.5" pipe off the muffler.

also if you have the non cali model "one o2 sensor" and no cat sensor, then you can cut the cat out with no problems.

 

really? i just put a piece of 1.5" pipe in there and hit it with a bfh a few times and the waffle just broke through.. this was for my 86

 

well i didnt get new pipe or anything... just muffler and tip. algranger, does yours run good with cat gutted? ive heard yotas dont run good and get really bad gas mileage with the cat gutted. in virginia where i live, any aftermarket exhaust, susp, tires that stick out, window tintand a bunch of other stupid crap is illegal. and mines lifted, tires stick out, and aftermarket exhaust.. so i might as well go out with a bang. a buddy of mine has a mustang and got pulled over for doin 75 in a 65 and got a ticket for speedin, exhaust, and havin racing suspension

 

i dont have a cat i got rid of it soon after i gont mine 3.5 years ago no problems since but mine is 20 plus years old so it dont need to be smog or and thing anymore i just get a sticker in the mail after i send them a check lol

 

Wow! And I thought California sucked ass. Maybe their equal. I guess the goverment has to do something to keep us sheep in our places.

 

yea in va..if it didnt come stock.. 99% of the time its illegal

 

There is a shop a mile from my house that builds these trucks for guys who get there money from who knows where. One of the employees, or owner maybe, drives and F350 that has to be taller than the one in this picture. The leaf springs are shaped like horseshoes. They are called Krazy Kustoms. Name fits. They've been in business for a few years too and are building a new shop in the automall area.

 

holy crap that thing is nice!!!! i love them strokers my brother has one. it has 6inch stacks, superchip, exhaust break, bigger injectors, and a bunch of other stuff. it smokes like a freight train

 

is that a classic example of a mall crawler?

or would the one ford i saw a few days ago on 40 somthing inch boggers with no front driveshaft count??? LOL i saw it at the mall too

idk, mine is a 90' 4runner. i thought it was in california its whole life but ill have to check again, and it had one 02 sensor before the cat and thats it

 

Double post. oops

 

I'm pretty sure that if it only has one sensor on the exhaust then its not a Cali model, but i could be wrong lol..

how ever if you only have the one sensor before the cat, then you can cut it off/out right in front of the cat. thats how mine has been for years!

 

i was wondering the same thing lol

 

That is the gayest pile of crap I have EVER seen in my entire life.

 

I hvae the Super 44 off-road muffler on mine with a 2-1\4" tailpipe. It's not LOUD but it's decent. I removed my cat also and replaced that whole pipe with 2-1\8" pipe as well.

 

I would definatly have to agree with that.

 

If i gutted my cat would my CEL come on?
I have the o2 after the cat
