I'm thinking of putting a milltek exhaust on my Fabia. Has anyone else used one and what kind of performance and sound differences did anyone notice.

Also has anyone had any experience with the Jetex exhausts for the Fabia?

No performance increase, some like their tractors to be noisier.

As said unless your running big power then no performance gain but it does sound very nice. My se has one and in the higher revs souds a bit petrolish. And the twin twin pipe looks nice.

I did think the look and sound might be good.

I have one on mine. I think it makes a better noise than most other aftermarket exhausts. It also fills the rear bumper recess quite well

Mine is a de-cat so there's a tiny performance increase from removing the restriction.

Does having a de-cat affect the mot at all?

If any car now was made originally with a cat then they cat should be present when having a MOT.

What other exhaust are there on the market that give a performance and nice sound

That's what I thought. I think I'll just get the cat back system. Easy to fit and should give the look and sound nicely.

I've seen the Jetex exhausts but have no idea about them. Good Information on exhausts and their sound etc is hard to come by.

If you leave the CAT in you won't get hardly any difference in sound.

 

Find your local Longlife exhaust franchise and then choose which type of tailpipe you want,they have loads on there website.

Go for a dummy cat and the smallest backbox they have,you will get a bit of nice noise then at full throttle but low down/town driving you don't get the chavvy noise you do with running no silencer

I've decided to go with a milltek system. When its been fitted I will post a comparison video on youtube.

No there isn't.

 

The standard OEM exhaust system WITH cat is fine to ~220 BHP after which backpressure may start to build at high RPM with a larger turbo fitted. The cat is not any more 'restrictive' than the missing section of 2.25" pipe it replaces, the entire system flows as well as a 2.25" open pipe, it was carefully designed that way by good engineers with access to powerful computers.

Well I do run in excess of 220 ponies.

Also there's a weight saving from CAT removal, albeit small.

Ive managed to get a milltek system. I will do a comparison video for anyone who is interested.

I have a Milltek cat back. It looks nice and sounds well when you are higher in the revs. It's not too loud but you can hear it.

The piper exhaust is meant to be louder but I guess it depends what you want.

My SE got 139.4bhp on the rollers. That was factory but with the Milltek. Although I didn't get a record before it was on.

Methinks you could do with a remap, that's a bit low for a standard car, the exhaust may actually be losing power without the remap.

139bhp isn't low for standard. It's only meant to be 130bhp. I have a shark map on it now at 178.9bhp.

I had 1 and found the twin pipes left a lot soot on my rear have now got a oval single pipe and its much better

Most BLT's are near 150BHP standard otherwise I wouldn't have said it.

I don't know why you're arguing about flywheel BHP figures on an RR.... May as well argue it'll be sunny tomorrow...

Normally I'd agree, in this case I'm simply making the point that fitting a 'performance' exhaust to an unmapped standard car will generally lose power, highlighting how silly these mods are when considered in isolation and also just how good the standard exhaust system is.

Straight through exhaust can be worse for performance than one with silencers in.

I don't think I pointed out that my vrs has been mapped to just shy of 180bhp. The milltek exhaust will be on next week so I'll see how it is and let you know.
