Default Syiths downpipe; CEL discussion

I'm going to start to try to get rid of my CEL with Syiths downpipe, and my hi-flow CAT. It had the CEL from his downpipe alone, when I reset the ECU it will go away for awhile. I'm also having engine problems that might throw that same CEL because of my AFR but I'm trying to fix that now.

1) Who has a CEL and who does NOT have one with the downpipe?

2) Whats your exhaust setup like before the last o2 sensor(just after the main CAT)?

3) What elevation are you at?

4) If you have a CEL, have you tried any of the extenders, ect to get rid of it? If you don't have a CEL, how many miles have you driven with the downpipe? Any 6k+ rpm shifts?

Please give me feedback, once I figure out a solution I'll probably be selling a kit to get rid of it, or telling you where to get one. I figure I should sell one with my headers so people don't have a CEL.

Oh one other thing, how many of you have done emissions with the downpipe? I know one of you told me you passed with it.

Danny

I have my own downpipe that is welded on. That then leads to a Flowmaster Hi-Flow Cat and 2.5inch piping to the custom headers. From there on its a 2.5" straight shot to the Magnaflow round muffler. No CEL, I solved that dilema by using a wideband O2 (innovate). But that only worked for so long until bank 2 O2 decided to shoot a CEL. So I used the extension trick which has been working for the past 3500 miles. And lotts of 6k+ shifts to boot. I mean thats the only way I know how to pull out of my driveway

And yes I passed emmisions, around here I have yet to come across a station which actually looks under the car, so I was free and clear.

Logikalone, you're still using a cat. you could actually weld a bung just after the high flow cat and put your 2nd o2 there. i think that danny is actually trying to get rid of the cat altogether.

i am not using a cat. my exhaust is as follows : OE header, downpipe**, OE flexpipe, 2.25" pipe, Vibrant Performance resonator, 2.25" pipe, Borla "Boomer". all of my exhaust components are straight through. there is no mesh-like material. i can pick up every piece by itself and look straight through.

**downpipe. i am currently using the OE to avoid the CEL. I had Syith's on, but it made my exhaust a little bit too loud for my liking. Limp mode or not, I don't like having any kind of maintainance lights on.

like i said before, i've tried the mechanical extension as well as o2sim. i emailed o2sim.com before i bought their chip and they said that they haven't had any complaints from any Suzuki owners. anyways, neither of them worked

Hey you said you worked at a shop on 51 or something - was all your work done there? How much would a setup like that run a fellow Reno owner?

No CEL's and passing emissions in PA with all of that stuff on board is a big deal around here.

The only way youll pass is if you have them inspect it. If you get the work done by us, then youll have no problem. A setup like thatll run you about 400 for the exhaust, 300 for the headers, 120 for the cat and downpipe. so around 800 for a complete exhaust from the motor back. All stainless with your choice of muffler and piping size.

What peices did you use? an actually kit for this thing or the spark plug Non-Fouler thing?

I'm probably going to try the spark plug one Friday when we build the first full mid-pipe w/ hi-flow CAT. It's pretty cheap and I wanted something I could throw in with the purchase of this stuff.

Do you know what elevation you live at?

haha, your neighbors probably hate you too

You kidding? My neighbors love me, unless those tilted eyebrows mean they dont...damn. But I used the spark plug non foulers. elevation would be 1223 feet above sea level.

Other than the annoying light, is there any negative things going on with how the car runs? I can put up with the light as long as I know that the car is running the way its supposed to.

Nope. Apparently a full exhaust or anything less shouldn't put the car in limp mode. Hell I've ran without both o2 sensors and it didn't seam to go into limp mode, just acted weird.

Which extension trick did you use? or better yet how long was it exact? any bends? how big is the inside of it?

I tried a single anti-fouler thingy drilled out to 1/2" and my CEL came on right away, haven't gotten to try two of the things togather which is what works for most cars. Some cars need almost two togather, 90degree bend, then nearly two more.
