Hey all,
Im curious if anyone has one of these test pipes? I know the increase the seller has listed looks a lil high, but Im sure it will have some increase. Any reason I shouldnt get it?

http://cgi.ebay.com/ebaymotors/ws/eB...tem=1849449866

 

yes can get one www.warpspeedperformance.com or www.testpipe.com

at least $30 cheaper.

 

I got one from warpspeed for around $30 to $40....I forget the exact price. The price is slightly higher is you want to have an oxygen sensor hole on it. The pipe also aluminized steel and looks better that the one on ebay and cheaper too.

 

Yeah, but will you pass emissions?

 

no. test pipes are for off-road use only (legally)

 

never!

 

Luckly I live out in the cut. No emissions testing here. I got ways to get it inspected.

 

Do all years need to 02 sensor cut out? Will a 1998? I know I have an 02 sensor in the catback and two in the Y pipe but what about the cat?

97 + do not have o2 sensors in the cat

 

Warpspeed test pipes are $27.00, total shipped $34 something like that.

 

anyone on here get rid of the trouble code that's given by having one?? if so, PM me immediately!

 

i never got a code...

 

I have not a code either

 

me too....

 

 

Everyone in this post is talking about the price at this site, and the prcie at that site. But what about power gains? Is it worth getting it and failing inspection? Because if it gives some noticable power than in on that!

 

it is not worth it unless you are s/c or have NOS..


the N/a boys will soo nothing really except if your present cat is clogged..

 

why would it make a difference if i was supercharged or not, im not arguing just curious, you probly know more than me. Help me out

 

 

It's great to live in KY! All emissions testing is officially ended as of Jan. 1. Of course, I guess that means the ricers will bust out the widest pipes they can find.

 

okay, no fair! when i first put my test pipe on, i got a code that's "Three Way Catalyst (right bank)", code 0702, and it won't go away. oh well, guess i'll have to buy another cat...

 

I have installed it on my 99 Maxima, there was no need to have O2 hole in the test pipe. O2 sensor is mounted in b-pipe, right after test pipe.

 

i have no o2 sensors after the cat..



all mine are before the cat..

 

Because the restriction in exhaust flow from the cat is negligible for stock or lightly modded engines, even at WOT and high rpm. But with boosted engines you have so much more exhaust flow that the reduction in flow resistance provided by a test pipe (and similarly for a larger diameter exhaust) becomes significant. Those higher hp numbers advertised are most certainly for boosted applications.

 

I got 0707, rear heated O2 sensor, after installing my test pipe. Since that sensor doesn't seem to affect performance in any way, I just live with it. It is a mystery why some people get CEL light and others don't though. On my 95, the O2 sensor is mounted in the pipe. I wonder if it is a grounding problem.

 

well, my last o2 sensor is an inch or two past the cat on mine. of course, what else sucks is i'm getting an egr code too (but i think that's just from my egr system blowing goats, i.e. "low flow") i kinda doubt that even tho they're both exhaust, the egr low flow would trigger or be triggered by the cat code. i thought about getting the dummy o2 sensor, but then you'd have to worry about your computer not making the proper adjustments to some of the changes that it should. oh, the misery of an aftermarket exhaust

 

You mean catback pipe, B pipe is next and then the pan

 

i got the code... 0703, left bank something like that... but anyways... i was talkin to my friend that has a domestic... and he says there's these things called a o2 simulator... used to trick the ecu in sending a signal that says that the sensor is workin properly... now i've searched for this and posted yesterday about it but i couldn't find anything... only stuff for GM's and corvettes... stuff like that... anyways... that's how you do it, if you don't want the code anymore... or get a RT cat and you'll be straight...

I think this is being caused by exhaust leaks. I put my test pipe on and noticed that it had a good 1/4 inch gap in lenght of being as long as the cat.....I bolted it up tight and can't find any leaks BUT the code says an exhaust leak will cause it.....any ideas?
I am pi$$ed of about this.....but my car Definately has more HP and it is NOT boosted (maybe a clogged cat???)
anyone ever figure out the solution (including a fake O2 sensor that fakes out the computer??)
2Maximas
OH mine just started this today.....3 days AFTER the install.......

 

Ok, so i hear about a possible CEL. But what about noise level? I ordered a y pipe from budget and it came with a free test pipe. I want to keep it decently quiet... how will the test pipe sound? Anyone care to share?

 

mine is MORE quiet with the resonated test pipe than with the cat......go figure...) maybe I had a bad cat? It also seems stronger to me. although it's in the upper RPM band now......
I am now getting the infamous 0703 code now though....(Three Way Catalyst (right bank))
I had a Nissan tech tell me that when you start screwing with them that you can EXPECT problems......and he does not work for nissan anymore, he is with an independant show now....so he is not "biased" in his info....

 

i did a test of the 2 awhile back. on the stock cat runs the weather was a hair worse, and my clutch was almost dead. after looking over the stats i came to the conclusion that there is not much difference at all between the two.

 

so if i use a test pipe with o2 hole i can use the sp2 for 95-96?

 

The reason why some people don't get the code is because like redmaxpa said, they might not have any O2 sensors after the cat starts. So there isn't anything to indentify that the cat is missing.

 

well it would have to reach your testpipe with o2 whole, since our rear o2 is in the b pipe

 

mine is quite a bit louder then it was with the cat on

 

can or can't be done? do i have to rewire the 02 sensor or what?

 

I reset my code and so far it has not come back, but I have not really dogged it either.......is there a way to fool the O2 sensors to deliver a good mixture? I DO NOT want to run lean......lean=burned pistons!!!

 

Now, this is an old thread!
Redmaxpa007 does not even have a max anymore. ha ha ha
it is a shame, because it was one good looking Crimson Blaze maxima.

I don't think the test pipe does all that much for performance. Ceasar's Chariot's numbers prove this.
