Decat - More noisy?

[OllieWinchester]

I have a 91 Eunos 1.6 with a generic stainless cat-back JDM exhaust on. I'm thinking about de-catting it because a)I think its knackered b)I want to increase my carbon footprint c)It doesn't legally need one anyway. Will it be noticably louder with just a straight pipe?*
Has anyone done this to theirs? I can't stomach spending £60 on what is effectively a piece of straight exhaust pipe so I'm going to try and find a friendly local exhaust merchant to remove the cat and weld a piece of pipe in, any idea's of what this should cost? Someone mentioned that I could just take the cat out, beat its innards out and then stick it back on, good idea or not?

• Secretly, I want it to be louder and raspier, because I'm still a boy racer deep down...

Excited now.....
Did you just get them to hack the old cat off and weld a piece of pipe in? Was told this was difficult because to weld all round the joins you need to drop the whole exhaust. £20 seems cheap too.....

Looks nice, but the whole ethos of my Eunos has been budget budget and more budget, seeing as the thing only cost me £600 and I use it once a week at most. I'm loathed to pay £50 + VAT and shipping for a piece of straight pipe that I could get with a hacksaw and a piece of old exhaust.

I've got a Jackson Racing airbox on the car at the moment, so when I'm giving it the boot all I can hear is induction noise which is lovely, but I just want a little bit of exhaust rasp too. Will let you know how I get on and how I go about it.....

Do you want to sell me your decat pipe for an incredible knock down price? I'm in the motor trade hence no money....



In all seriousness, is it just a case of wriggling under the car with a ruler and measuring how long the cat is to know which decat pipe I need?

Just been browsing on MX5Parts website. Surely I don't want this..... http://www.mx5parts.co.uk/product_info.php/product...

It says it is silenced? I don't want it silenced, I want it loudened......

MX5-Lazza, you absolute legend. The last ebay one you found is 5mins away from me, and it ends Sunday night, so hopefully if I get it then it'll be fitted by Monday morning. Been scouring ebay for ages, can't believe that one slipped under the radar! How much difference between the noise of a straight pipe replacement and one like this.... http://cgi.ebay.co.uk/mx5-de-cat-pipe-stainless-eu...?

In fact it feels so good I'm seriously considering selling my Focus and getting a dirt-cheap Mk1 as a runabout.

Do it, they are ludicrously cheap now. Look in the classifieds, there is a tidy looking blue one that sold on here for £875, if I didn't have a company hack I'd definately be using my ratty little MK1 on a day to day basis.

Fitted the decat this morning, not really noticeably louder TBH....

I have some sort of JDM stainless rear section on there, but it is a two box system, one big rear box and a smaller one before the bend, maybe this is why. Can't see any markings on there to say what make it is or anything....
