My 94 maxima began to make big noise this morning, and I found that there is a big hole on the flex pipe tonight after searching here. I still have some questions: I gueess I need to replace the whole Y pipe in order to replace the flex pipe, right? How much is it to have it replaced in a local shop? If I want to DIY, which one I need to order form WPS? Thanks for your help.

 

is your 94 a gxe or an SE?

gxe = vg pipe
se= ve pipe

careful replacing it yourself, you might snap a few exhaust studs in the process (then again, a shop might do the same, NOT tell you about it and charges more, pick your poison here I guess.)

 

you can have the actual flex pipe replaced, but most shops will charge around $100 or so to do the work.

It is far more beneficial to replace the y-pipe with a warpspeed one and be done with it. Yes, it will cost more, but you not only replace the busted out flex section, but improve performance.

 

depends on how much money your looking to spend, when my flex was leeking , i had them cut out the flex and put a new one in, cost me ~$85 the warpspeed Y-pipe is 160 or more dunno if they run that special anymore , i doubt your doing a flex replacement yourself unless you have a lift and a welder available, the y pipe i think you could just jack up the car and undo the 8 or so exhaust studs and just disconnect it and put the new one on wd-40 is a friend with those studs , dont crack`em.

this is good stuff. get one.

 

heh; when i repaired my flex section, i got worse gas mileage.

shoulda left it alone

 

lol did they do it right?!

 

The same thing happened when I had my flex piece replaced!! My mileage went from 23 to 21 mpg (now it's at a solid 18...go figure).

I'm suprised about how cheap the flex pipe repairs were. I payed ~$300 for my repairs...but I'm not sure if they did something different, or what. I should've just bought a new y-pipe to eliminate the flex piece in the first place.

 

the "replacement" piece that my maroon max had , had several extra bends in it and a shorter flex

 

the "bootleg" y-pipe

 

I called local shops today. Midas quoted me $130, and Meineke $170 for replacing the flex pipe. Warpspeedperformance.com is weird, I cannot find a link to place an order, and the ebay store doesn't answer my email. I cannot wait too long because of the noice pollution, neither do I want the lower mileage.

 

call their phone number and place the order!

 

i swear to god, the best gas mileage i ever got was with a hole in the flex section and a 3 inch filter on the intake tube. everything else stock.
it was quieter with the fix, but i swear i lost some torque and gas mileage. not to mention a lot of attention...haha.

we have a "Thrifty Muffler" here in town and theyre pretty cool. i remember the fix was pretty cheap. not even a hundred i think. they bring you in and show you what the **** is up...theyre actually the ones that informed me that i was missing manifold studs...shoulda brought it there when i test drove the car!

 

Leaky flex = lost performance. No two ways about it. I should know, I had to replace my Cattman Y flex about 3 times before saying "F-it" and welding my own custom flex and 4-gen hi flow cat. Standard flanges suck too. Ball joint type is the only way to go

 

well maybe you thought it felt faster because it soundedl ike a V8??

 

I went ahead and ordered the Y pipe because I was told the pipe was in stock and ready to ship. I checked the pipe again carefully tonight, I think the biggest problem to replace it is that the studs between cat and flex is really rusty, I will have to destroy them in order to remove the pipe from cat. What should I do for the rusty studs? Thanks

 

wd-40 them up < shrug >

 

broken flex is so loud! i just got a new flex pipe and it;s much better

Help.
I am replacing the two CV boots on my 96 NIssan Quest. The drive axels have been off the car, but I have difficult to disassemble the CV joint. I rent a slide hammer from advanced auto parts, but it doesn't work possibly because I have to use one hand to hold the axle and another one to hammer it. I don't have a vice. The car has 120,000 miles on it and it seems that the axles are original nissan parts (I bought the car at 110,000 miles). I checked the CV joint, it seems that the inner race has a little room to move in the cage, is this normal?
Now I am considering two options:
First, I can have the joint disassembled in a shop if the price is reasonable or I do it myself if I can get tricks to do so from here.
Second choice, I will purchase two remans for $89 each from advanced auto parts or other stores that you recommend.
I am sorry I ask help for a non-maxima car, but it has the same engine as maxima. Your help is highly appreciately.

 

just buy 2 brand new ones.
they are cheaper than the remans, and no core hassle
