3" exhaust parts list

[rj scotty]

To save me time it would be really helpful if those that have built turbo back systems could post a basic parts list.

I assume a turbo to meet standard back box cat delet set up on the avant would look something like this:

(All 304 grade)
Flanges
2x tight radius 76mm 90 bends
2x 76mm 90 bends
76mm to 58mm reducer (turbo outlet to down pipe)
76mm flexi
2000mm 76mm tube
1x 90 42mm bend
76mm to XXmm reducer (middle section to back box)
3x 76mm vband
2x M18x1.5 boss with bung
1M 2mm flat bar
Any thing I missed

Lamba boss

I would have 2x lambda boss, and 1 x egt boss to future proof.

Really depends on your routing, avant will be different to coupe too. For the downpipe I used a 90 bend, 2 x 45 bends, 1m staight, v-bands, 2 lamda bosses, flanges, a 90degree 1.5" for the wastegate pipe and some 2mm plate for hangers etc
I've forgotten what I use for the for the centre section I have used a 100mm flexi, 3 x 45s, 2 x 90s and about 2m staight, vbands and some 6mm bar for hangers. It's hard to keep track I cut up that many bends

Was your down pipe 90 tight radius?

I want to source all the bits from one place hence the list

center section on the avant is a piece of piss

If you need to look at a 3inch system from turbo back I have one on my car..

You may have seen it though

What did you cut the pipe up with Alex?

14" abrasive cut-off saw
Don't buy a cheap one they don't cut straight!
