well if its not one thing its another.after replacing a defective new strut and a front precat on my replacement 03 i find that the flex section is shot to hell to the point i have alot of exhaust movement and noise.Does anyone know the OE flex section size length and diameter? i dont want a new y pipe until i order some catmans in a few months i just want to replace the flex right now and keep moving.I did do a search but nothing about the OE size in the 250 post. TIA

 

I've asked a similar question about the size of the stock y-pipe piping and didn't get a response. I'll be under the car tomorrow checking on my PS, and I'll measure that sucker for ya!

 

Man, I wish you would have posted this earlier this afternoon. I just got done reinstalling and buttoning up my y-pipe with my cat, pre-cat and manifold. Damn timing. Looks like you've got someone to measure it anyway.

 

well it looked like i needed more then a flex section which im still working on.The main cat was smelling like rotton eggs this weekend so instead of buying a new replacement cat i got a magnaflow full SS 2.5 in/out from amazon for $47 and a pair of vibrant SS flanges for $26 welded them up and all is good.i do have one other problem i need to quiet down this damn Megan exhaust any suggestions? has anyone used a 4" x 28" resonator and cut out the Megan unit? also im still needing the OE flex section size if anyone has it i would like to get it and whatever soulition for the excessive exhaust noise done soon.

TIA

 

mine isnt looking to good either. i noticed napa auto parts has universal flex pipes. go buy a couple and then return what didnt fit.

 

Sorry to bump this but did any of you find out the size of the flex pipe?

 

Never did and i still need to replace it.

 

haha alright I'll go under and find out the length today, probably assume 2.5 diamete although its probably less.

 

Man you finding out the size is going to create more work for me.

 

It's either 2.25" or 2".........

 

Did you crawl under there yet and get a size?
