eliseparts de-cat

[jaykaybi]

Can anybody here offer some idea of what I'm getting into if I pull the trigger on a cat-replacement pipe from eliseparts?

Obviously I know what it means regarding MOT etc, but are there other problems/issues/points of a relevant nature that I might not have been expecting?
It sounds easy to fit - is it? (I'm no mechanic!)

Cheers in advance to all who can offer any insight!

James,

on an S1 (which it seems you have from the picture, nice colour too ) there should be no issues with the pipe. On S2's it can cause the MIL light to come on with associated probs, but there's no MIL light on the S1 so jobs a good 'un.

Funnily enough i finally had mine refitted today after a recent MOT. I got a local guy to do it for 40 notes, but if i had access to a ramp/inspection pit i'd have had a crack at it myself, it's not meant to be difficult at all, just a straight section of pipe with three bolts either end. I believe it can sometimes cause a bit of blackening around the pipes and tailgate area, but other than that i can't think of any problems. It doesn't do wonders sound wise, but it does make a difference. They can be picked up very cheaply now so give it a go....

Edited to add:- What single pipe 'zorst have you got on there J?

Depends what exhaust you have fitted, but on my last S1 with a sports 'zorst it made the car considerably louder - to the point that noise limits on some circuits would become a problemm for track day use.

here is a video clip of my s1 with Sports exhaust + Decat + induction kit in a tunnel

The quality is a bit gash as its on a digital camera, but you'll get the idea

save up for the high flow cat instead.
It'll be emission legal and same power.
On my Honda Civic there was 1hp difference from de-cat to high flow cat ,and this was an engine with 170bhp and revving to 8800rpm.So the difference is probably close to 0 on an elise.

no difference really other than noise on a std (ish) engine ...so its lots of noise, hassle at MOT, illegal if you get stopped etc ...wouldnt bother myself - get a sports cat if anything

I loved my car with the decat pipe on (Sport 160 + ITG induction + Janspeed sports exhaust), very loud with lots of pops and bangs on overrun. Have put it back on now for MOT and as I'm selling it, car's still bloody loud but seems to run a bit better with it on so it's staying on.

I'm aware that it's illegal if stopped but how would plod know it was there?

Surely not from the smell of the exhaust alone?

Hollywood - I checked the receipts with the car and apparently it's a 'Supersport' oval exhaust.

Sounds good to me, what's the forum consensus?

You're very unlikely to get pulled, but if you do you'll fail a roadside emissions test. Cue a producer and maybe a fine. Then you'll have 14 days or something to get the cat back on and get it retested as OK.
