fitting decat pipe

[vxer]

Hi guys,

I\'ve got a decat pipe which i want to fit this weekend, but i thought i\'d better check with someone in the know exactly what i have to undo / contend with.

I\'ve attached a picture of some mysterious bolts which look like they might need undoing. Anyone know what i actually need to undo under there apart from the obvious bits?



Cheers, Paul.

ps. this is part of the decat pipe - i think the end which connects to the downpipe - is it supposed to be angled like that?

[McCARTHY]

what make is it? does it have any bolt holes?

[Fish]

Nope the ends should be flat. not angled.

Not sure about the bolts though. Sorry

Its japspeed and yes it does have bolt holes.

Bought it from ebay here.

Crap. Thats the end of that then!

The downpipe came free with this, but its for the american car - i expect its been designed to work with that... Arse arse arse.

Ta, Paul.

evening

I believe the bolts you\'re looking at just hold the thermal casing onto the CAT. Mine didn\'t even have it!

as for the angled flange not a clue as all the flanges I worked with were flat.

sorry bud

...actually, thats a little bit dodgy isn\'t it? The ebay guy is selling it as a decat pipe, but it only fits with the free included downpipe but the downpipe is for a LHD car...

Hmmm.

Cheers, Paul.

Those sytems and set up on \'E-bay\' are cheap for a reason...

 It always cost you more in the end, spend proper in the first place!

Well, it was £100 after postage, so thats hardly cheap!

Not that I want to be an "arse" or something but a good rule to live by is..
"If you buy quality, you only cry once"  Sorry it doesn\'t fit though.

[vxer]

Well, i\'ve just spoken to the bloke who sold it to me and he\'s adament that ppl have fitted this mid-section with no problems to the stock downpipe.

Seemed like a nice chap - offered to give me a refund if it doesn\'t fit.

Just want to double check with you guys first - the downpipe\'s flange faces vertically and horizontally flat, pointing exactly towards the rear of the car?

Cheers, Paul.

Mine sure did mate on a UK car. UK\'s have a pre cat which is what I bolted the new exhaust to but would imagine the original cat would be the same for UK and JAP.

In a word I\'m pretty sure that it should be as you said the flanges should sit flat.

TBH, thats what i would expect too. However, i even contacted japspeed directly and they also say that it will fit ok onto the stock components. Guess i\'m going to have to have a proper go at it. :/

Cheers, Paul.

Hey,

If you do get stuck with it if you measure it all up I\'m sure you could get a adapter made to sit between the 2 with an angled flange and a flat flange. The smaller this is the better though else it will push the rest of the system back however far this part is wide. If it does come to an adapter type jobby if you don\'t know anwhere I\'ve mate who machines stuff out of stainless who could probably do it for pound notes

Actually looking at your pic again the angle is very slight so you may be able to come up with something. Alternatively cut the angled flange off and have it welded on flat

Thanks Garath, thats very kind of you to offer! My welding skills are non-existant!

Good idea about the adapter - i thought of bending it, but discounted that idea because it would lower the exhaust too much (or raise it into roof of the floor, depending which way around it is!).

I let you know how i get on!

Cheers, Paul.

Yay!

It looks like this story is going to have a happy ending! I remembered i still have my old rusty HKS cat-back in the shed, so i got it out to mock up the exhaust on the ground to see if it would fit.

Low and behold, the catback\'s flange has exactly the same funny angle on it! Horrah! On the other end of the decat pipe, the flange sits flat to the pipe which will meet up with the downpipe perfectly.

Now all i have to do is fit it!

Cheers, Paul.
