Stainless sports exhaust advice SE6

[Hardparker]

I'm looking for a good sports exhaust system for my SE6A. can anyone point me in the right direction. I currently have quicksilver tubular manifolds and to be quite honest they're rubbish - they only have a short drop to the collector and lasted 6 months before cracking. the worst £200 I ever spent!

would prefer matched length manifolds to improve flow. advice on bore sizes.

Hi, Only ones I know of off the shelf are from the dealers, only got experience of Walkers and they're not too bad, don't like the flexy ball joint otherwise ok and 1 3/4" bore iirc. If you want them matched with a nice flow into the collector, then go for 2 1/5" bore, but then ground clearance issues come into it. Depends how low your car is, of course these would have to be custom made and probably cost more than double the price of Walkers, if not more. Then you'd have to get a 2 1/2" system to match, straight through with rear silencers frees up loads of restriction in the middle boxes.

I think the ones - they're a 'Double SS' design, originally - that GW sell are the best you're likely to find without commissioning a set yourself.

I used a pair on my 5a and made the rest of the system up myself using 2" Jetex bits - there are no difficult bends, so if you have access to a welder and a hacksaw it's easy enough.

Thanks for the advice Nick and Paul,

1 3/4" at the manifold then. Thats the size if the ports anyway so larger would just create problems.

2 1/2 on the rest of the system from the collector back. I'm thinking on "V" gate baffle in the mid box and straight through on the tail pipe.

Design isn't an issue as I have a friend who works with CAD - gas flow dynamics programs come in handy But I would need a good fabricator.

Are GW supplying Double S or copies? Are they matched length, sequential phasing or just where they fit?

sod it..... I'm going to take the plunge and invest in a TIG, pipebender and a flange tool. I'd never be happy unless I built it myself anyway

looks like a few hours of measurement and CAD ahead (and a some strange looks from the missus when the new kit arrives)

anyone for a matched set of stainless headers I have an SE5 and SE6 so I should be able to supply for both. may be a few months before the first one gets done due to equipment costs but once I got the pattern I can knock them out in a few days.

and it'll make the job easier when I build my BOA powered SE5
