i'm gonna get this done because i actually scraped a hole in my flex pipe and ended up with an exhaust leak last weekend. stupid flex....

also using header wrap helps. if you're interested you can look for my previous thread on that.

Don't you need the flex pipe??

SatinSilverTypS

it's not critical. you may need to use new gaskets because the fitment of the flange may change when you straighten this pipe to weld it. i don't think any other headers have a flex section though so i'm not worried. i'll see what my local guys tell me on friday when i bring it in.

I saw him Sunday and his car doesn't hiss anymore and sounds 100x better

black_tl

sounds like an idea

MrAlex

look like mine .. same problem .. scraped it and leaking problem .. after just put a strait pipe on it .. this was 6 month ago .. megan 3nd batch..

^^ So did welding in a straight pipe get rid of the resonance? Or did you not have any to begin with?

Bxscig

Do you have the resonance now after the scraped part was replaced?

MrAlex

No its great now .. before it was like a biiiizzzzzzzzzz .. but not that anoying.. just remplaced because of the hole on the flexpipe..

joseph_99tl

i'm gonna see if i can get this done.
i scraped my flex pipe a few times.
it's all mangled and now it's hissing.

thanks for the post, penguin.

joseph_99tl

hey SSTS.

be sure to post back how this turned out.

fsttyms1

All headers have atleast 1 flex section, Even the oem unit. megan happens to have 2.

MrAlex

No need for new gasket.. just cut and solder another piece..

z3Ro

yip...did that to mine daaaays ago

i should have clarified, i know that you're going to have one at the cat, but i didn't know of any other manufacturer using a 3-inch at the base of the downpipe. unless someone else knows of one......

will do, i'm going to get this done tommorow morning.

OIC I wondered why you would want to remove it. Well in that case, that was retarded on Megan's part.

I wonder though, wouldn't this rewelded section be prone to cracking over time?

SatinSilverTypS

iTrader: (1)

allright, got it done this morning. it sounds 350% better. cost me $100 with my tire rotation. i highly recommend it! i can still hear it, but it's so muted it actually sounds cool, as it was meant to sound. no more rattlesnakes under the hood.

PenguinQX - i would say yes, but as with any weld on any header or piece of metal, alot of it depends on the ability of the welder. and the way i see it, even if i have it rewelded twice, then the headers still only cost me $450, about 1/3 the price of comptechs. if it happens a third time i'll chuck em.

i'll post some photos this week. i haven't had a chance to get under the car yet.

^^ Nice! I'm going in for an oil change soon, as well as new brake pads (getting Hawk HPS put in)... I'll see if the place will fix my headers for me too!!

moahdriven

i should of thought of that a while ago...next time im back home im gonna have my muffler shop do that, the bottom of my flex pipe is already torn pretty bad from speed bumps an shiet.

Phesto

You guys got me thinking about this,but I read a post in the CL forum where this guy said it did not work for him.........any new info on this??

PenguinQX

iTrader: (1)

Dropped my car off for oil change+new brake pads... The shop doesn't do exhaust work though, so I'm going to have to wait to get this done... This might have to wait though, I need to get these new springs+shocks on, they're taking up too much space in my dorm room and if I don't get them on before school ends, I'll have to store them over the summer!!

i dunno man. worked just fine for us. i mean i can still hear it, but it's not *anything* as bad as it is in stock form. i think it sounds awesome at full throttle. i can't wait to put my icebox intake in now.

i guess i'll put it this way. it cost me $100 with my tire rotation and i had to wait 3 hours at the shop, but it was worth it. although i did have an annoyingly loud exhaust leak from the flex anyway when i brought it in, so it would have been worth it to fix it anyway.

FINALLY

im headed down to golden auto asap to get this done

Trojanman750

can someone post pics of the STOCK flex pipe before welding......i wanna compare the two so i know what to tell my exhaust guys........i remember when i had some pretty nasty tears on my headers from speed bumps and shit, hopefully its the same as what you guys are talking about

joseph_99tl

post pics when you're done.

Trojanman750

i should be getting this done next week....cus i will be on spring break and at home and actually have time to get work down

here's the megan short flex:


here's the stock flex in front of the cat:

joseph_99tl

ha!.
my flex pipe looks worse.
it leaks exhaust also.
i have it header wrapped right now..but it still hisses.
thanks for the pics.

fsttyms1

Header wrap wont stop a leak. Have a shop remove the front flex and leak

Mike_McCready

So if I get Megans and replace this: http://img127.imageshack.us/img127/7...raid0vx0ik.jpg with a straight peice of piping, there will be no resonance issues?

SatinSilverTypS

iTrader: (1)

that picture was taken about a week after i got the headers. i developed a loud leak last week so that's why i had it taken out and straight-piped. the wrap was really to deaden some sound issues where i thought the headers were hitting the subframe and adjacent components. it worked out for me.

i will say though that it's been 5 days since i had my flex re-welded, and i feel like the car drives better now. throttle response seems better, acceleration is stronger and it sounds sooo much better also. i wasn't expecting any of those improvements, except for the hissing going away.

my icebox just came last night also, so i plan on putting that in today and getting a dyno soon.

SSTS

Trojanman750

ahhh so the flex pipe is the peice of the header that has that weaved design and sticks out a bit....if so mine is BANGED UP!! the exhaust guys saidi had a small leak there too.....definately getting this done asap

Trojanman750

THIS WORKS!!!!! HOLY FUCKING SHIT THE RESONANCE IS GONE!!!!!!!!!!!!!!!


it only costed me 50 bucks at golden auto in san francisco. i got back in my car not knowing what to expect. after a slow rev the resonance is completely and totally gone. on top of it, this weird grinding noise i thought was caused by my failing engine mounts was also eliminated


I HIGHLY RECOMEND THIS TO ANYONE WITH MEGAN HEADERS

Phesto

i live in SF, where is golden auto?..................and your sure it works right this resonance has me close to getting the DC's, which may be another problem

Phesto

did you also have your headers wrapped trojanman?

joseph_99tl

i went to one guy here in NJ.
he said he didn't have the kind of welder need to do stainless steel.
i have to find a place.
my flex pipe is in bad shape.

SatinSilverTypS

if you need a temporary fix autozone sells a "goop" you can spread over any hole to stop the leak. it dries rock hard though so after a day it will break off since that pipe will flex and cause it to crack. it only takes a second to apply though and silences the leaks pretty well. just an FYI. i did that for a few days before i got to the garage.

SSTS

Phesto

just got this done today at Golden Auto and man is it great 20 minutes and $50 dollars later resonance is gone,they did a nice job getting rid of that troublesome second flex pipe and replacing it with a straight pipe.Wish now I only did this sooner.........if you have megans go do this now.
