My latest bolt-on
 

The pipe at the bottom of the pic:


I dont need no cat:



Still have this cat though:


I noticed a definite gain in power and my Apexi WS exhaust sounds a little louder but in a GOOD way.

Word. That mean you can bolt the non living cat on for emissions ?

yup, got it sitting in the closet ready for emissions testing next year.

word to that. cutting and welding = :no:

i like your cat ;)

how much of a difference? we dont have E check around here so i could care less

hmm its hard to say how much of a difference there is, but I used to hate, HATE driving around with my A/C on cause of the lack of power, now it drives waaay better with the A/C on. With the A/C off there's, of course, also a gain in power. Its definitely worth the 48bucks I paid.

I think a Cat-back exhaust is essentially useless with a restrictive ass cat right before it. When i took out the cat and looked through it toward the sunlight, I could barely see any light, now if light can barely get through, do you think air is going to have a hard time? I think so.

hmm...im surprised it doesnt sound like shit after the pipe went on...is it at least a little buzz-ier? Or not at all?

Ive been debating this lately...

no, absolutely no buzzing sound. let me put it this way, My friend who drives a 2000 Trans-Am WS6 heard me come across an intersection one morning. Two days later I saw him at work and was telling him how I replaced my cat with the pipe, he was like "you did it before monday didn't you", I said yeah. Then he said "I knew you musta changed something cause when I heard you come across -some intersection-, I was thinking damn I didn't think Rob's car sounded like that" as if he was impressed. So if it impressed a muscle car guy I'm sure there is absolutely no buzzing. To me it actually sounds deeper and more...aggressive would be the right word.

SO DEFINITELY GET IT!!!

eh...i would but Id throw a cell for sure
so
either an o2 simulator that really doesnt work
or
obd1 conversion (and its the ecu that i dont want to buy)

i thought there were o2 simulators that worked?

yeah...they cost as much as an obd1 conversion.....

i thought they were only like 45bucks

a MIL is I think what its called, basically fools ur ECU into thinking there is still a cat there...

"MIL" stands for malfunction indicator light... it's the abreviation for the check engine light in a honda...

As far as the straight pipe...

Pdiggity...

You're not turbo it will do little if anything for you... a hiflo cat will do just about the same...

AZ...

Have you tried a hiflo cat?

I wouldn't drive around without a cat... I can understand at the track to decrease the 1/4 times but for daily driver it's kinda irresponsible in my opinion... no reason to pollute when you don't really need to.

I wasnt thinking about it now...but somewhere down the road when that kind of issue came around.

Ive always heard that the cheap simulators didnt work...maybe I was misinformed

i maybe polluting more than a normal civic but I'm sure its nowhere near as bad as most vehicles on the road today, so I dont really care. plus a straight pipe is cheaper, and I'm cheap.

haha u cheap bastard...;) i guess i'm not the only cheap one around here.. :yes:

Dude, my friend's $30 homemade O2 simulator worked fine on a 99LX. Radio Shack is the shiznit! I have the link on the Step by Step forum and my website. I have one of those test pipe myself. Im just waiting to have my friend build me one of those simulators.

Not to harp.... but more to inform...

EVERY car after 71 or 72 has a cat... ANY car without a cat will produce MUCH more polution than ANY car without a cat...

Your civic probobly puts out more harmful gases then a cat'd v8...

Not positive but pretty damn sure...

the cat converts certain MUCH more harmful gases into less harmful ones... so every car with a cat isn't putting out hardly any if any of those gases (specifics escape me at the moment)... where as ANY car without a cat is POURING them out...

I see where you're coming from with the cost factor and what not but a hiflo cat isn't much if any more than a test pipe... and also isn't much behind it in performance... the universal ones are 50 bucks and direct fits are like 100 or so....

Not preaching... do what you want. Just figured I'd put it out there.

hiflo cats suck and cost like 500

Is that a joke?

Mine was 100 shipped. (direct fit) the universal catco was 50.

It definately opened things up a bit... not too big a difference as I'm 1.6 na... but for FI it should help considerably.... over stock at least.

but you'll feel more of a diff. w/ a turbo, if you've taken the cat out as AZ did?
