ok my n1 cat back has finaly gone out on me after 4 hard years of driving so i guess i should go custom i dont plan on goin FI so i want 2.5'' from the dc collector mod the the muffler. are there any cons to my idea? and whould 2 bolt flanges be ok for all the connections?

 

Looks like a pretty good plan, close to what I want to do.

I think you should run a hi-flow cataylitic converter instead of the
test pipe though.

It will sound cleaner and be less harmful on the environment.


BTW: not a bad drawing either

 

And more: mind you really don't want the resonator that shaped... You'll have a free flowing exhaust so gases will be flowing quite fast and they will destroy the back wall of the resonator (this is what I fight with now... Every 2 months I have to weld this bloody wall). Look for the resonator which is oval-shaped (more less like an egg).

Edit: correcting logical English error

put the primary o2 sensor where it used to go, just weld it into the header, that way you wont have to extend the wires to reach the harness, and if you ever put a cat on there, you could still have a spot for the primary o2....

you should condsider, like pentaq said, getting a resonator that tapers back into the pipe....check out the ones on all the catbacks.....something like that....

 

Leave the catalytic converter on , for every 1 vehicle without a cat it's like adding an extra 10 cars worth of pollution to the road.

 

SKDRCR - thanks the problem is im tryin to save as much cash as possible i dont have much to spend on the car rite now its just that the exhaust broke so i gotta fix asap and thanks for the complement i like to draw


pentaq,mgags7 - ok so go with a different res. and i just forgot where the o2 sensors went i thought they where both on the cat so the exhaust should be more like this


integra15 - my cat is gutted with an o2 sim the cat melted on the inside and i cant afford a new one so if i cant find a good price on a hi-flow i will use a test pipe im sorry i have to admit im not too woried about the environment but im tryin to get the exhaust done befor the cops find out im running without a muffler

thanks for the help so far

Thats a damn nice pic - looks like the 5th gen Prelude lights on front and a del sol rear.....

 

del sol tail lights? do they not look like 5th gen tail lights?



i still wana know if the 2 bolt flanges would be good for the collector to test pipe/hi-flo cat or should i look for a 3 bolt?

That's quite possibly the most retarded thing I've read all day.
You can't afford fifty friggin dollars?

 

what the hell? you callin me a retard? i said i cant afford a new stock cat its not 50 bucks jack *** im still choosing between a hi-flo cat or test pipe i cant pull money out of my *** so i got to go the cheapest way possible

No, I never said that you were a retard, I specifically stated that your post was retarded. Oh, and thanks for referring to me as a jack ***...and here I didn't think anyone noticed my avitar....(awww...how sweet...)

CarSound for $53.75 *SHIPPED*

Add a foot or so of 2.5" pipe and 2 flanges and you have yourself a direct-fit cat for little more than a test-pipe and you aren't beating mother earth's ***...

 

That picture looks exactly like my exhaust, except the o2 is before the test pipe.

 

I wouldnt go with a test pipe if i were you, i would spend my money on a high flow cat. I have both the test pipe and a high flow cat, i removed the test pipe because it made the beautiful sound of my GReddy SP2 sound like ****. The high flow cat will remove some of the raspyness that is heard with the test pipe.

In conclusion... High Flow Cat &gt; Test Pipe

 

ok if thats what im goin to get from a test pipe i guess im goin to look into the hi-flow cat jax sorry for snappin but like i said im short on cash this is just something i have to do cuz i dont have an exhaust rite now

and still noone knows if i can use 2 bolt flange at the collector to cat?

 

hi flow cat &gt; your stupid test pipe.

why the name calling twords me? im just tryin to get some help on an exhaust that isnt goin to cost me alot and just before you posted dint i say im goin to look for a hi-flow cat

 

nice drawings there, another downside to not having a cat is the exhuast will stink up your car...and you, but to each his own.

 

i have a test pipe with the cat on too

 

why do you use both at the same time?

what do you mean?

 

My exhaust is basicly just like the drawing, though I don't have a flanged test-pipe, just solid from the header to the res, and also with an N1, 2.5" pipe. It's loud, and after driving mine for a fair amount of time now with this exhaust, I'm very sick of the volume. I've almost got the cash for a high flow cat finally, so I'm hoping it will quiet down a bit.

I also get the point now, for all those that bitch about the pollution when people mention test-pipes. Backing the lude in my small garage every day and then getting out of the car into noxious levels of gasses gave me an idea of how much **** cats realy do filter out, my garage never smelled like it does now back when I had a cat, and soon it'll be back to those good ole days.

 

i personally would run a resonated test pipe w/ o2 simulator. good sound + good power.

 

im running a complete megan exhaust with the megan Hi flow and its sounds very nice. really deep. not ricey at all
