Yeah my o2 sensor is about 5-6 inches in front of the cat drilled into the pipe.
So i could cut my cat out if i wanted to and it shouldn't affect much...
But i doubt im going to do all of that.

 

the flowmasters and the cherrybombs are nice, but my vote is on a hooker muffler. straight pipe would be miserable for anything other than a diesel or v8.

 

yea i hollowed mine out, didnt do much for performance, but it sounds way better. and i live in one of the few counties in ca that you only have to smog it once as long as you still own it.

 

How exactly did you go about hollowing out your cat?

 

well i took the exhaust from the cat back to the muffler off, couldnt get the cat completely off. then i drilled, chiseled, hammered and did whatever to get all the crap out of there. there was also a wire net around it and i just ripped that out with pliers. blew it clean with an air hose, then put it back on. sounds real good now. however, i recommend doing this AFTER you smog it. i didnt think about that and as a result, im putting a new cat on today to smog it. but im keeping the old cat to slap back on.

 

Well in good ole South Carolina, We dont have to pass smog tests

So i might just do this...

 

lol i wouldnt say the straight pipes were misserable just extremly loud on my 3.0 hahaha but the cherry bomb extreme was loud to but nothing like straights. they were 2 totally different tones also

 

I pulled the cat, set it end up on a steel work table and put a punch through it with q hammer, easy as pie. Thank god those cats are ceramic, the platinum ones are a huge pain in the keister

 

yea probably the easiest mod ive done to my truck

 

Anyone know how the 3.0 sounds with a gutted cat?

 

i had a gutted cat with a dynomax i think it was, when i first got my truck and it did make it deeper and louder but it had an annoying echo sound to it and that no cat smell lol

 

Ive got an 85 toyota truck with a 22r.. Im needing exhaust work and i cant decide what muffler to put on it...flowmaster or cherrybomb?? or whether or not to run it all the way out the back of the truck??? any help guys?

 

i like the cherry bomb extreme. ive ran both dumped exhaust and tailpipes with tips out the back. i like the tips out the back because it doesnt drone as bad

 

^^ agree! I have a flowmaster 10 dumped right before the rear diff and it does have a drone to it. If I would have done it again I would probably pit a tailpipe.

 

I put a cherry bomb on the truck today and ran a tail pipe. Its not really that loud. I reckon im alright with it. Thanks for the help guys!

 

dont take it off just put on a 40 series. there are cheap and will sound so much better and will keep the back pressure which will actually maintain the same amount of power whereas is you ha nothing it would be faster for a little bit until the engine blew.

 

exhaust cut out, run a turbo muffler after the y pipe and throw an electric cut off valve for performance and sound at the touch of a button.

i would get a flowmaster before i straight piped it. straight pipe just doesnt sound good not on a 4 banger at least
