Does anyone have any idea as to what performance gains are likely from a set of equal length downpipes?

You have to see the exhaust system as one complete unit, manifold to tip. I doubt changing one bit would make a lot of difference, but as you remove restrictive CAT's and make the flow as good as it can be then you should gain a few BHP, not masses though. You will really enjoy the noise though.

I must admit I'm a little nervous these EL pipes might make the already very loud Wizard exhaust unbearably loud.

Any thoughts on this combo from a noise level perspective ?

I wouldn't expect much of a volume increase, it might be a little more noisy when its cold as the stainless downpipes will be especially resonant then and the Wizard cat-back will amplify that. But once its warmed up I wouldn't expect a great lot of difference.

I'd agree with Pud on that score - the first time I fired up after fitting mine, I noticed that the volume was a fraction louder (or hard edged?) but the tone mellows a little after the pipes warm up.
On the plus side, the "drone" from the exhaust on the motorway is less, as the lumpy firing order is eradicated after fitting the EL's. Sounds creamier basically.

Less "Max Power", more "Maranello"!

Ordered a set as well to be combined with Wizard, Not sure how long they will last on a lowered car but worth a try for that money. seeking more refinement and tone.

If they sound great it might be time to investigate a shallow or dry sump setup.

I think I'll have to replace my saggy old springs before I get some.

Just fitted mine in exchange for Alfaholics downpipes.

Fitting was more or less straight forward but needed to remove bracket on the gearbox support to make room. Easy but you just need to support the gearbox while removing bolts.

Ground clearance is not so bad. Mine is lowered 30 mm with Eibach springs and yellow Koni dampers so was initially concerned. But after a good bit of driving I have no issues. Suspension is rather stiff though so that might help compared to standard.

Sound is unreal. Mine is CF2 with Alfaholics decat, Alfaholics center section (free flow) and Raggazon straight through rear. It was fairly loud but fine for a weekend car. Volume is more or less the same now. Idle is a bit softer and more balanced. Past 4000 rpm it screams more like a V8 which is new. Drone is a bit less. Really happy.

For the money I can only recommend.

so the before and after................................ you just changed the cybox downpipes from the Alfatune ones that were there before and the rest of your system was same as you described, And you consider the Cybox downpipes a better sound rather than the Alfatune ones you removed.

is that right as i was thinking alfatune rather than cybox.......................... coincidentally what you doing with Alfatune downpipes then

Alfaholics DP's are stainless OE replacements.

The Cybox and Alfatune ELDP's are essentially the same.

Previous was Alfaholics DP not Alfatune. Alfaholics DP are not EL.

Cybox supplied the EL DP to Alfatune so they are the same apart from a 50% mark up.

I thought that Gus at Alfatune designed and fabricated them himself and sold them as his own design and manufacture ???


although the pic on both Alfatune and Cybox is identical so either generic image or they are same product

I thought that to. Isn't the alfatune just single formed tubes with no welds besides the flanges.

Alfatune and Cybox are identical.
I have bought EL down pipes from Alfatune and Cybox and they are the same.

My best guess - Gus conceived the idea, designed them, commissioned Cybox to make them.

They are the same. Manufactured by Cybox and rebranded by Alfatune.
