Does anyone know what is the length of a test pipe have to be for a 5.5? IS there any place online I can get it? Or if you got it custom made, how much was the total cost?

I remember that a while back I read somewhere you can use the stock cat as a test pipe by knocking everything out of the cat. Does this work or does it cause problems?

I see some test pipes on Ebay but I believe these do not fit. Please correct me if I'm wrong. I see lengths of 12.5", 13.5", and 14.5". Are any of these the right one?

 

The stock cat is 12.5" from flang to flang. I know for a fact that the megan test pipe is 13.5" you can MAKE it fit. But as someone with one, don't.

 

so what would u just suggest though pulsar?

 

^^
Honestly Im in the same boat. The test pipe I have now pushed the whole exhaust back 1" which is enough for the section near my RSB to bang against each other every now and then.

 

You could always buy one and then take it to a muffler shop and have them cut it to correct size.

 

or try and find one made by warpspeed.. i have one.. measured its close to 12.5..but i havnt installed it yet.. thats 4 after winter

 

Pull the cat and take it to an exhaust shop. It comes out very easy. Have them make one with that as a guide. All it is is a straight pipe with two flanges on it. It's an easy job for a good shop and they wont be breaking any laws by removing a cat.

If you hollow out the stock cat it sounds really funny because of the way it increases in diameter.

 

Mine was made too big as well. So I took it to work cut it in half then trimmed 1" off and re-welded it. Not sure why all companies out there make them way too big.

 

didn't know warpspeed made one, how much was it?

 

Thanks for the responses guys! Appreciate it.

For those who have gotten a shop to cutom make you one, how much did it cost?

So the size that should fit is 12.5?

 

Just leave the cat alone. Running a test pipe will do more harm than good. Dont pollute mother earth or Al Gore will come bite your head off!

 

and manbear pig will get you

and he is ssssuuupppeeerrr serial

 

12.5 sounds right, I don't have it anymore since I got the bung for my wideband installed.

 

i picked it up off a member on here for 25 ish shipped so idk what they would charge... from here... http://forums.maxima.org/5th-generat...h-springs.html

PM him maybe he knows what he paid

 

ir just pay an exhaust shop $50 bucks to weld in a 1 foot pipe...

 

Really don't want to bump this but it's pointless starting a new thread...
anyways, will the s13 240sx test pipe fit? This looks like the flanges are shifted a bit. Is it the same on the Maxima?

 

you could just have an exhaust shop take a piece of 3'' pipe and weld flanges on it for you if you cant find one.

 

I purchased one of the 30$ ebay test pipes and it fit my 01 just fine.

 

Was it the s13 3"?

 

FWIW: The 4th Gen test pipes are the correct length and fitment. And they are usually cheap on eBay.

 

I was looking at those the other day. I'm gonna see if I can compare my stock cat to the cat on a friends 240.

 

Maxima exhaust isn't 3" so no, it won't fit.

Just get a Maxima test pipe off of ebay.

 

Thanks man, it would really make it cheaper!

I have a 3" exhaust so it would be complementary instead of a 2.5"

 

I finally got my 4th gen cat next to a 240 cat. They look identical. Same flange angles and both cats are the same length.

The 240 cat is still connected to the rest of the exhaust in these pictures.

 

40 bucks or less shipped....

 

I had the 40$ ebay one and it fit fine, went back to a high flow cat now tho.
