The guy I spoke to told me Peco folded in 2011 and they absorbed some of their tooling and staff, they also took ownership of the Peco name. He also told me that they had worked with Alfatune to make their downpipes. I was trying to push to see if this means they are the same but given a different name and as far as I can tell the answer is yes. They are SS, lifetime warranty and use mandrel bends. Cybox can do them for 307 but if several of us get together and they make a batch it will be a bit cheaper (easier said than done). May I suggest that if you are interested the first step is to speak to Jerry/Gerry at Cybox on 0151 343 0330. He is very helpful and I think maybe Cybox have realised they have missed a trick here. I think I am going to go down this route but not instantly, mainly because I don't have my car at the moment (it's being restored and is sitting in the paint shop queue).
I am CF3.
Well done James - count me in, at 307 (or even less), they are great value compared to Alfatune. Maybe Gus is a reseller??? I will call Jerry tomorrow and put my order in.

Cheers for the info. I expect the web site said that but in Japanese, so I was clueless (not for the first time!), they do say a little knowledge is dangerous lol.

1. They remove drone from the exhaust ( should there be an after market exhaust)

3. The lower rev range is .... ..... I am not sure how to explain but drone is removed and it is a bit meatier when under load. 2000 revs let's say.
4. In the higher rev range the engine just screams

Overal they make the v6 sound more refined. Not quieter. Not louder, but refined. They make the v6 sound even better than it did before. And makes it sound like it is of a much more expensive and exotic Italian marque. These make the v6 sound even more Italian.
Thanks of the info and the experience. That's rather what I thought from the you tube vids, more refined. I'll certainly get some at some point.

Both versions have their own clearance problems due to how the pipes are routed. CF2 usually cross over one another so clearance is reduced by the diameter of the exhaust plus the 10mm gap between the two pipes, CF3 quite often just wiggle around without passing over each other, but they pass under lower points on the engine than the cut-out through the sump (bell housing, diff housing), so this also means clearance is reduced.

I'd be super interested to see what these CF3 ones look like if you get some, and also what you think of them when you've had them fitted.

My take on the sound is that EL pipes remove the "boxster" off beat burble (like a Subaru) and produce a more even regimented "straight six" sound, which is more creamy and smooth sounding.

If exhaust pipes are unequal in length, the sound from half the cylinders is slightly delayed, resulting in a more lumpy sound.
(Think Harley Davidson compared to a Japanese four cylinder bike!) Not quite the same technically of course but for a convenient example it works nicely.

Does anyone know if they do a V6 stainless sports cat?.. Don't fancy paying for the Alfaholics one. 307.00 for these pipes is great, on the shopping list!

Cybox do sport cat and decat for V6 cf2, I've seen them on eBay. If you call them up you'll probably find they do them for cf3 too.

Edit: just had a look and can find decats cf2 & 3 but not sports cat but like I say if you call you will probably find they do. Other option is buy a universal 200 cell and get power flow or long life to make you one.

TBO i like the boxer-esque burble, Because my flexi pipes are blowing I just want the cheapest and easiest way to replace the front down pipes! My mechanic said I could just buy new ones and have them welded in but it maybe more sense to just replace the whole thing, with stainless steel straight replacements. And with the EL pipes I'm slighty put off by the way they overlap each other and would they catch on speed bumps or uneven road surfaces for example?!
