with that set up, you'd be best to leave the stock cat in for tourque, and if u remove the cat u can damage your exhaust valves,trust me....if u wanna throw a highflow cat in, put a 2.25 tailpipe or stock tailpipe on it,then you'll really be a rock star

@negrodamus1000 yea im not going to mess with the cat. too much ecu confusion. tight now i already have 2.25. thats what comes with the cat back. i might put a glasspack on however because to me, its not loud enough.

howd you make it so it didnt throw a check engine light?

[jeepfool007]

lol I havnt gotten to that... I would like too but I gotta figure out how. I've seen people fool the ecu with resisters but that was with the cat still on... I might just do spark plug non faulers and gut out cat

[jeepfool007]

the cat back i didnt notice much mpg boost at all just a hp and torque boost which was nice, the cai gave me a 1-2 mpg boost. not much but im sure you could pull more with new plugs and rotor and cap. i drive mine hard though so i was happy with the 1 mpg up. im getting 16.8 mpg right now.,

year ago? what do u have now? thx for the comment.

i've got a 96 zj with a 4.0 and i am running 2.5" pipes no cat and flowmaster super 44's and mine is fine. feels the same as it did with cats on

@timinator824 There is a computer chip you can buy that overwrites the CEL, but dont let them see it when u go for inspection :p

@negrodamus1000 I hollowed out my Cat', Now i dont drive it on the road too much, but lets just say with and intake, holloed cat, cherry bomb muffler, all in a 95' yj, hard doors,5spd, hard top' I burried the speedo on the higway beating a 95' eclipse. Then messing around i raced and integra with a JDM gsr, and i pulled on it 2 lengths by 50mph.

I have to say, It may be bad for it, but I had it for years like that, the only thign that finally broke was the T-case. It msta gave it atleast 40hp

[stormer1092]

is that a lid of some sort or the air intake?

[dnl5649]

@jeepfool007 dont put spark plug non foulers on, they reduce hp by like 5-10 per cylinder and the fuel isnt burnt right

and if i do not start moving by that time , it jumps up very quickly , so what i do is just turn the motor off once it reaches 190 un-tell its time to go :) , and as soon as i start moving it falls back to 150 , guess thats how poor boys do it hehe , also i would advise NOT to run your vehicle in this manner unless you know what your doing ......

[the404man]

@ryanpm92 you know i was thinking , i had taken off my clutch fan , to replace the water pump , and never put the fan back on , i cant see how that would make such a difference , but , i also noticed a huge power gain as-well .. yes im running it with out a fan , the idea was to install an electic fan , just never have since it doesn't get hot " no thermostat " it runs about 150 , it will sit at a red light , but if i have to sit too long yes it gets up to the normal running temp , 190 - 220 ..

[the404man]

@ryanpm92 idk bro , thats just what the thingie says up on the roof console , when im driving it easy , but if i get into the gas it drops down to like 6mpg , and now thats the real time mpg , though i can get it to 32 real time , but yes the average mpg is 26 hwy travailing
