Hi im going to fit my new exhaust today but im wanting some help from u guys on here the exhaust ive got fitted is in one piece from the cat back and the new one has a center section and backbox
what im asking is at the front where it attaches to the cat its bolted and has springs on. when i bolt the middle section to the backbox is it ok to just bolt together or do i need the springs on this bit aswell?
i have gasket sealer ect but im unsure of the bit above so all help is welcome
cheers

just use nuts and bolts mate, you only really need springs where it attaches to the cat. to allow slight movement really.

ps. only a ten minute job to swap too.

 

Before you attempt to undo the bolts soak them in a releasing fluid such as WD40 overnight. I soaked mine for about an hour but one of them still sheared. Had to manufacture a new one from bolts and washers etc. The back box to centre section has a gasket between them and is just bolted together ( no springs ), my gasket was shot but exhaust came with a new one anyway so no probs, not sure if you could get away with using just jointing compound. Easy job though, should take about an hour if that!

 

ive just realized that i have only got my trolly jack as i chucked my axle stands when we moved house so i dont know if i want to try to do it with just a trolly jack?

 

Don't even attempt it without axle stands, you need to get right underneath to gain access to the cat to centre section bolts and also the back box to centre section.if i were you just soak the bolts now as best you can while you go and get some axle stands. Seriously dangerous without axle stands !

 

DONT work under with jack only

 

I have some very good Axle stands i got cheap and they are rated to 3tons. Cost less than £20 quid and your life is worth a damn site more than that.

I couldn't imagine anything scarier than being crushed by your car when working underneath it so i take all precautions.

 

just take it to kwik fit or something and slip them 20 sheets

 

yeah so wen u ground out or scrape ur mid section on gods finest creations which r speed bumps...ur exhuast being bolted together and with no room for flex as ur without spring loaded washers u`ll just end up shearing or even worse breakin a stud off or crackin the cast on ur turbo ....which happens.:O:O:O

 

tried them the other day and they both said they will not do it as i havnt bought the exhaust off them but im going to take it to my local exhaust place on tuesday when it opens. its doing my head in i have a new exhaust sitting here and i want to put it on my car

 

its got springs on there from the cat to the center

 

which exhaust did you get mate ?

 

the joys of your own garage lol. i bought and fitted mine yesterday.lol

 

fit mine for me then

 

u not got car ramps u drive up onto mate seeemples lol

 

As far as I knew, the springs are there to keep additional tension on the nuts in order to stop them working loose from vibration but you can survive without them. They're not there to allow the joint to move since if it did that, it'd break the seal of the joint and allow exhaust gas to escape prematurely from the system. Also if you think about it, the joint is still done up with nuts and bolts so would only be able to move if you left the nuts and bolts loose. If the manufacturer expects any part of the system to need to move then they'll usually use one of those "flexi-hose" joints.

Oh and if you hit a speed bump hard enough to rip your exhaust off or wreck your turbo then that'll learn ya for driving like a pleb through somewhere with speed bumps

 

i learnt the hard way and wis no a speed bump was a rock in a mound o earth on a beach i say try it without and see how a get on !!!! U HAVE BEEN WARNED ha ha

 

... perhaps a land rover might be a better choice of vehicle if you intend driving on beaches mate?

 

ha ha ha hard to see humps wen ur sideways

 

wouldnt be worth the fuel for you mate, i would have if you was closer.

 

Do it yourself rather than letting someone else. You'll learn something new as well as having the satisfaction of saving yourself a few quid that could be better spent elsewhere.
