stress on exhaust/manifold. fix?

[chiboy002]

i put a straight pipe on my car, its in 3 sections and deletes my cat and resonator in 1 peice. it has 2 pipes which form from a split at the downpipe flange connecting to the manifold, which is a megan.

the exhaust has LOTS of pressure pulling down, probably cause it is shaped badly, or the manifold. im not sure, but for me to raise it enough to get onto the hangers i need a jack. and then it only reaches the rear 3 hangers. i didn't think much of it until now when doing research but can i risk breaking anything cause of this?

one of my rubber hangers tore because of the pressure on it, so i need a new one of those. what should i do out of these options?

metal custom fabbed hangers?
Circuit sports 50% stiffer hangers?
Nissan hangers with metal hose?
flexpipe on the manifold (since i cant have it on the downpipe cause of its shape)

someone help cause im so lost on this, currently i have 2 ziptied hangers to be stiffer and then a ziptie holding on the torn hanger. and it still sags

.... Get a new exhaust... Either re-make yours or just go out and buy a new system or have one made for you.

Flex pipe is the only way

completely out of the question. this exhaust is godly, two straight pipes all the way from the manifold back? only part on my car i will never get rid of, even if i choose to sell the car. taken from crimsonrockett and brian harte, its made by a EXTREMELY rare company. not to brag :boink:

Flex pipe is the only way

would it be alright if i have a flexpipe on the manifold where its flat? its the megan 4-1, the area where some stuff for intake hoses and shit go is flat, so i was thinking there?

its this one: http://got-jdm.com/JDM/images/240SX%20Stainless%20Steel%20%20Headers%20Exhaust%2 0Manifold.jpg

mmm... you could get new hangers and re-make the hanger posts...? or try a different header, maybe the megans are the issue.

[importdude]

flex there is fine

[chiboy002]

flex there is fine so if i take it to a shop or something they should be able to do it? sweet

i think it might be the megans, or maybe the downpipe but im not really sure, both options are difficult to check since i dont have another mani - what would another manifold company be that isn't too expensive and is of that length? i know OBX or something has one but its huge, not something that would fit my system - i need an s14 manifold as well since my flange is a 3 hole

i don't think its the hanger posts though cause when i lift it with a jack to get the hangers on, they reach the hangers and have perfect fitment on the car, but when i lower the jack the exhaust drops a good 3 inches, give or take .5inches

use the factory transmission down pipe mount

[essforteen]

And Use worm clamps on your stock rubber hangers so they dont sway too
much and keep the exhaust more solid!!

[chiboy002]

use the factory transmission down pipe mount

with that hooked up, none of my other posts line up! the one before the wheels don't mount right, and the final 3 are too high, with the way the exhaust sits right now... which is bad fitment


if i let it all sit alone, with only 1 hanger supporting the exhaust it doesnt scrape at all, but it does bounce too much for my comfort

[TheRealSy90]

put in two flex pipes, problem solved.

where... there is only room for one since the downpipe has no empty space, nor do i want to mess the downpipe up :/

thats definitely what im opted towards once i see what the problem is man. cause my main concern is that with the exhaust sitting higher up, the manifold is getting ALOT of stress and it would crack or something

[badicalradical]

Sounds like the flanges are angled more than they should or maybe you motor is leaning back ridiculously? Maybe your trans mount disintegrated combined with new motor mounts?
Seems like a stretch though.

BTW if you loosen the downpipe to manifold bolts and hold the end of the exhaust where it is supposed to sit relative to the bumper how do the hangers look?

Just a thought.

thats what 97240TB (http://zilvia.net/f/members/97240tb.html) had said about the flanges, but what about the mounts being melted? wuuuutttt??????????????????????? i don't think my engine sits tilted, or at least i havent noticed it if any, not sure though and will check tmro!

if i lift the hole think with a jack to where it SHOULD sit, and mount it on the mounts/hangers then they don't stretch at all, none of them. thats it i lift it to the same place the apexi that came on the car was, but once i lower the jack the thing comes down with. my hanger tore in half where the post goes, so thats how much pressure it has pulling down - they were worn but still thats some thick rubber

I don't know. People always say you need flex pipe this flex pipe that to save their manifolds and exhaust and down pipe. Then megan made that down pipe with the flex pipe in it

I've always ran a solid down pipe and megan manifold. I gone off the track and bent 1 exhaust and put a hole through a test pipe and still have no problems with fitment and lining things up. And i attribute it to that transmission to exhaust mount.

[essforteen]

The main reason the exhaust isnt lining up is because the manifold was made to be
used with the megan downpipe which is made for the s14. the Geometry of the KA is
different than the Geometry of the SR so they dont line up correctly causing all your
problems. I run a stock sr down pipe on my car to delete the CAT but it had to be
extended and clocked to fit right. Your problem is the downpipe was made for a Sr and
your car has a KA. You might have to redo the manifold to fit right.

i dont want one for taking stress from the exhaust bouncing, the only reason i thought one would help is because my exhaust sits WAY too low without the hangers, with them it causes LOTS of pressure

alright, so i shouldnt need to buy a new one? crimsonrockett is who sold it to me, he told me his friend had it on an SR, so it fit with that. It doesnt need to be clocked cause it fits fine the way it is - flange wise. but should i take it to a shop and have them angle it upwards more? i would go for the megan downpipe or something, but as you can see mine isn't exactly universal

btw i REALLY want your battles, lower price!! :) haha jk i have no money for it right now

read my upper post... i will never be changing this exhaust out. not even for tickets.

people love their blitz nur spec r, i love this exhaust. out of the question, and sorry bud but im not cheap, exhausts from ebay sound like shit
