3" turbo back 316 stainless steel exhaust, home made!

[quattro]

Got most the bits for my 3" turbo back exhaust now, cant wait to get this up and runing, cost so far is around £400
Turbo and Wastgate flange 2.5"-3" taper
2 meters pipe 3"
3 x 45 mandrel bends
3 x 90 mandrel bends
1 x 180 mandrel bend
1 x lambda bung
1 x 100 cpi race cat
1 x borla silencer

Just need to get 0.8 316 wire, small diameter stainless pipe for waste gate and thats it i think.

Have many others made there own exhaust?

Good effort! fair bit cheaper then getting one made else where, mine cost me £1000 all in..

Looking forward to the pics.

Good luck.

if you would have bought 304, everything would have been three times cheaper.. and there would be no difference in the final result, since its only exhaust, not exhaust manifold, where the good stainless steel is needed btw my calculations might be wrong,since i dont know much did your cat cost

I did my own(there's some pics on my red ruby thread) car was on axle stands when I did mine, a ramp would have made it so much easier, well worth the effort imo,
dont get too much heat in the wastegate to downpipe join cos it pulls like a git and dont line back up(I had it braced too).
must say car feels so much better with it.
have fun.

Really? show me where you could buy all this for £133.33 please.

I built my own system it's very different to most peoples. The 4" down pipe was a good two days work. And I also have 4 boxes.

i will be building my own when i do my engine swap, interested to see how you get on mate
as said I think heat warp in the downpipe and getting it to fit just perfectly will be the biggest hurdle - but sooooo much cheaper than getting one made.

die you buy the flanges or get them laser cut to the OE template?

4 boxes, for trackdays i asume?
How the hell did you get a 4" in there?

Got them from Dhalback when i bought the cam gear and some other stuff.

[Error404]

i think chef got creative with the subframe

I'll have a look at at Dhalback for the flanges

Well its 4" down pipe to twin 3" for as close as i can to 700hp and external waste gate pipe.

Please dont say you are using a DBR cam pulley?

Not only is there sod all price difference (certainly not from AALCO where I got mine), but actually the 304 is superior for heat properties anyway. 321 is better than both but near impossible to get preformed bends and hellishly expensive by comparison.

I have stacks of 304 straight and bends and a bit of 316 for some bends (just a case of what was in stock at the time), 3 inch and 2 inch x 16 gauge...

(...there is sure to be spare material when it's done so I might have some for sale at a later date...)

...plus flanges made by Wab (my turbo outlet flange has a built in start to the cone taper as requested by me) ...got a small piece of 14 gauge sheet for the cone and to make some of the minor brackets ...waiting on getting the engine back in place so I can do a mock up DP.

Er no, i was goint to untill it landed on my doorstep, material soft as hell and the woodruf key WTF is that all about?
