Hey

I'm about to buy a new exhaust and I have decided on mongoose, but the last exhaust I had stainless system (used scorpion) it lasted 5 month and then it started to rattle big time. A friend of mine bought a used mongoose and it too started to rattle.
A suspect it being because my clutch has some judder, but have any of you experienced this problem?
I don't want to buy a new mongoose just to find it rattling within a year, cause then I might as well buy a used system and get someone to fix it when it starts to rattle..

 

I have a major rattle on mine, but thats just were its lowered & catches the odd speed hump. Had scorpion on my other motors & havent had any trouble..

 

get a magnex as the have the flexi....but not as nice soundin as a goose

 

Have thought of that but I really miss the sound the scorpion made, and the goose seems to make the same. And yeah only the magnex have the flexy... hmm tough choice

 

My Magnex was rattling at about 3500 rpm found it to be the metal braid on the flexi pipe, Jubilee clip around it soon shut it up.

 

hey mate....

U gotta remember, those system we got home, were used... so I dont think you should have ane conserns bout buying a new goose... go for it... you heard the sound of mine..

 

you can also buy just the flexi section, i dont have one as my engine will NOT move an inch :P

 

can u fit a scorpion back box onto a magnex system with the lexy pipe??

 

not really an issue as far as i can see!?!??!

if you want a flexi, get one and have it welded into the goose.

if the goose rattles, its not broken, its just not fitted right

 

Went thro the receipts the other day and mine had a Magnex fitted with the flexi back in 1994 with a lifetime guarentee. Covered 33,000mls since then and sounds sweet as a nut. Tough choice mate !

 

you can fit a goose with the magnex flexi tho will have to be 2.5"...also if i remeber right the back box will stick out a little further!

 

buy a new mongoose, and if it starts rattling send it back!!!

thats what you pay.

i've not had problems with mine.

sayin that it did sound like their was a bolt in it but turned out to be the wastegate partly open.

it has a little penny like flap that is riveted on and when i backed the actuator off to regulate the boost it rattled.

not that that will be your problem if you've not messed about with yours.

turned out my amal valve was shot!!!

 

i use the magnex with a flexy and a 4inch mongoose debaffled backbox, no problems with mine,, sounds good aswell!

 

my last exhaust rattled like fcuk it was the metal pipe in back box that has all baffles in had broke at 1 end and it was this that rattled it drove me mad had it cut open and de baffled it sorted problem.got rid of it now though got a new mongoose

 

Just bought a series 2 turbo a couple of weeks ago, it has a full mongoose system and im wanting to get rid of it already. Cant go over any speed bumps or have anyone in the back seats without it catching. sounds sweet so i don't know what to do.

 

Get under there and adjust it mate, i have the 3inch bore mongoose and it took a bit of hit and miss to get it to stop hitting the car or the ground, it can be done though just takes a bit of messing around

Oh and also.... make sure any U clamps are turned to the side and not to the ground as the nuts were catching on the floor with mine (painfull)
Hope this helps

 

iains2rs must not be fitted properly m8 or maybe lowered too much?

 

How about that i just got my car chipped last friday and am rinning a 3" bore goose and have since noticed a rattle high up the revs in 1st and 2nd gearhave just come back in pissed of as i was wondering what the fook it could be was starting to think bad thoughts so why is it exactly they rattle

 

what is the better system to go for out of scorpion and mongoose? im more after power as opposed to the noise. got a magnex at the minute but not all that impressed

 

this is wot i know not opinions but facts:

magnex is the best fitting exhaust will not rattle or anything and is the only one to have a flexi which will dampen the vibration, only downpoint to this system is its not as loud as the others
Scorpion sounds good but is the most restrictive so not very good performance wise, no flexi so not as good fitting as the magnex
Mongoose is the best for performance and sounds the best too, once again not as good fitting as the magnex.

The problem with the systems without the flexis is that if you have an engine which cant stay still the vibrations go to the exhaust and can possibly snap off your bolts doesnt happen all the time but can happen, way to get round this is to fit a flexi!!!!

 

Nice one mate will look into fitting a flexi pipe was starting to get really worried when i heared it

 

I got the same problem at the moment.

 

no problems with my mongoose at all, and i fit it

im suprised

 

Cheers for the tips will give it a try next time im off work, hope it works.

 

Not sure who actually fitted it but it does not look good. only lowered -40mm. will try and get some pics and let you all see how bad it is.

 

i have a magnex with a flexi pipe but the problem i have is when i hold the revs at about 3500rpm theres a loud buzzing sound from the flexi pipe might try jubilee clips

 

I have exacterally the same problem!

 

might get it replaced with just a normal pipe. I thought it would have been my old flexi pipe and fitted a new one at the cost of £80 but the problems still there. Can sound quite nasty when holding at 3500rpm

 

Yea, when i do it, it sounds like my engine or something around there is vibrating to death!
