this was the last thing i suspected to be causing my car to make crappy power. i was at the point of selling the car if i couldn't find the problem. thanks to the advice of jeff evans i pulled the DP and there it was


anyone else have this issue?

BTW i'm not posting to bash full-race. i'm just so ****** excited about the find!!!!!!!!!!

yee SERIOUS

iTrader: (1)

how did that happen....

86si

no damage at all. thats why i never thought to check it. i'm just glad i found it.
funny it still made 392whp on 14lbs through that little hole...lol

blackeg

hell yea dude! i mean it sucks to know this happened, but now you know the problem!! huge stress relief.

wierd it collapsed, you exhaust isnt low to hit anything from underneath...

one of my friends had his flex joint go bad on his car, but he was hanging weight from it for a lil while

86si

thanks matt. na man that pipe never came into contact with the ground and it was brand new when i got it. it has seen very little use due to all the BS i have gone through.

Yeah, i've seen them fail like that. It's not from outside damage, the internal braiding collapses. I've spent A LOT of hours trying to figure out a problem that came back to that! haha.

that happened to a few dps in the past....so we switched to a different mfg/style of flex/bellow and havent had problems since then. how old is your dp?

Makes me think I may not be reusing my $40 SS flex joint off my 'practice' exhaust after the steel rusts... Looks so odd, like its an eyeball staring at you.

I'll never have to worry about that because I'm probably the only one on this site that created a ball and socket setup instead of using the standard flex joint

I know it's not pretty, but it uses off the shelf parts and a 3" off the shelf graphite donut.

You might consider doing something similar instead of risking the problem again.

This is my functional prototype from 4 years ago, it has still never let me down. I bought 2 donuts at the time, but have yet to replace it...you can unbolt it and work on it if it ever needs repair without removing the DP. You could also just weld it on.

Bailhatch

huh, I always thought the ones with the internal braid were better for some reason. Probably when they get pulled a little the liner slips out of the crimp on one end i guess

ahobbs

Maxboostc1 had that exact problem. its ugly lookin....lol
that's why you use flex pipe with ribbed insides.

can you make 300hp on a 2.5" dp, ahhhhhhh yes. i guess we don't have to hear that question any more.

It was closer to 400whp.

Dude its awesome its such a minor problem.. Sucks you went through all the other **** tho.. I was startin to think it wouldnt be ready til Mason could drive it

Tyler H

Yup, I did the same thing about 3 years ago with a flex joint I got from some diesel supply place. My 3.5" dp necked down to 1"! The inner braid actually cost me more because it was "better." Did you run the two step through it? I thought that was what caused my damage.

where can you find ball and socket joints at, ive been lookin, but no luck.

Turbo-charged

thats how i went from running 10.70's to 10.20's at the same boost level last year. i spent SO LONG trying to figure out my problem.......it was funny when i found the problem, i was in the process of taking EVERYTHNING apart b/c i was so pissed off. once i got the downpipe off, i happened to look inside to find that. cut it out, put it back on the dyno, and gained over 100 horsepower.

kranked91dx

It happened to me a few time, I used to build DP with a cheap Felx pipe I was used to bought at a muffler shop around here, supposed to be good all around flexpipe.

One day I realized that after making a 3in dp for my car, the car went laggier with utilisation time... at first I checked the turbo bearing.. no shaft play.. and found this...

Now i use the flex pipe that are metal cored inside and braided on outside... I can get pic's if someone don't know what I'm talking about. about 10 DP made with them since I switched and not a single problem.

A few down pipe I made with inside braided flex pipe are still running find for your information... failling is prolly not systematic.

The problem is, you can't...I made my own.

PM-Performance

Ive never even seen braiding like that on the inside. The ones I get have the harder flex sections and then the braiding on the inside.

Mr. Vapor

lol,

when i was up getting tuned by Jeff he actually said he saw this happen once. Wierd that it happened to you also, good thing he was able to help ya out!
