Exhaust building advice needed
I need a decent new exhaust.
I bought a westfield competition stainless steel exhaust manifold but it doesn't fit my locost. It clashes with the chassis diagonal where it
wants to exit the engine bay.
Silly me. Never mind. but what to do next? Sell the westfield manifold or chop it?
I made my last exhaust system by chopping and rearranging an existing one. Happy do the same with this one but it seems a shame to cut into a nice
piece of kit.
Those that have done it - how much does it cost to make one from bought pipes bends and flanges?
I'd be making a 4 into 1 from 1 5/8" headers and a 2" tailpipe
Any advice generally on economical sources of flange and pipe for exhaust builders?

GET RID GET RID LOL
I bought one of those for mine, ended up cutting and rewelding the diagonal brace.
After that I had to buy a gear reduction starter motor as the manifold fouled the solenoid.
After that I had to get some spacers machined up to push the manifold out to clear the new starter.
With the silencer I bought it all ended up costing me like £500!

Getting closer to hitting the go button on my draft ebay ad now!
What should the "buy it now" price be do you think?

I've just made my own exhaust for my straight six. Laser-cut flange was £50, silencer £70, then I got loads of steel bends for £2 each + a few
meters of straight pipe.
The mental gymnastics a landlord will employ to justify immoral actions is clinically fascinating. Just because something is legal doesn't make
it moral.

I paid around £120 for my westfield manifold off ebay - seen them go for 150 too.

I just cut the diagonal brace on my chassis, welded it 2" higher by the firewall and its fine.
Seemed a lot easier to me
Actually, i think you should sell the car and build a new one around the exhaust :p
NS Dev bought a industrial 2nd hand tig and the bends for less than a brand new simpson exhaust + had enough bends left over to make another
exhaust.
If you're happy with stainless wire in a mig i'd guess you're looking at easily under a hundred quid.

Hey Benz,
You're not far away from me, where did you get your bits? esp the flanges?
thanks

Mine was around £125 which included an R1 can.
Made the collectors, ended up with a couple of bends over.
Purchased
8 x 90degree 1.5" stainless elbows
1m x 1.5" stainless straight tube
1m x 2" stainless straight tube
R1 can included the link pipe, very important!
Regards Mark

If it's any help:-
I've just bought a 6M length of 2" 316 for a job. £11 per metre.
2" 316 bends were just under £8 each.
From Aalco.

Hey Mike,
Tempting though it is to build another car round the exhaust.......
Problem is I'm booked on a hillclimb driving school in April (xmas present from my lovely wife) and have to get the car under a legal noise
level and tuned before then.
How does your car handle with the chassis bracing modified like that??  
It would be great to catch up btw, long time no see. Do you fancy a post-holiday cleansing ale with the S Brum guys on Monday night?

Flange was from wayne (Idontbelieveit) on this forum. The bends were from lolocost, I turned up and they had boxes of various bends, I got about 12
(m/s btw) they also had ss bends.

All the stainless for both my exhausts (one each side) came to about £200 (not the ones in my avatar, they were mild steel and would advise not to use
as rusts too quick) - see blog instead.
I made manifolds from 316 butt weld tube (allstainless.co.uk/com?), can't remember who supplied manifold flanges, had turbo flanges cut to my
design and rest od pipework (for can/perforated tube/straight tube and 3" bends were from milner offroad.
Lot of time - especially the polishing

Thanks for that.
Then I had a look for exhaust photos in your archive and got distracted...

Thanks for that - found their website and Aalco looks the real business. I think I'll give them a call.

Dave,
That's my sis-in-law - I figured she might not want to be plastered all over the internet, and the Mrs might not be too impressed with me not
having a pic of her in car
It was taken by my bro - him and his sprogs went by tintop to pub, Sherene in toy car. I think you can tell she was enjoying it!
Quite a good photoshop job I think
