I want to replace my stock Greddy downpipe with something custom. You all know how restrictive it is.
Stock looks like this - (photo stolen from Hornetball - no your not the last one left if you count the UK!)
And I'm looking to change it to 2.5" , to match the rest of the system, something like this infamous tony DP -
Now I have a MIG. My dad welds well (Mig, tig, arc, braze etc,) and has given me it, to learn with. I can throw sparks and make things stick together. I'll get better.
I have a mild steel flange. I will be putting a flexi in and some way of better supporting it in place of the OEM bell housing bracket. I can get some 2.5" tube and bends easy. I guess I'll need one tight bend to come straight off the flange.
My first bit of proper fabrication. A learning exercise. Where the best way to start?
Remove original stuff. Bolt flange to turbo. Start cutting. Tack first section. Keep going till the ends meet up. Take it all off and weld up properly.
Any advice? Just go for it?
The existing setup is 2 pc - Greddy pipe, stock pipe to the cat. Doing it in one piece is going to make it a lot harder to fit, right? I guess that pictured ^ has to be snaked in from below with the turbo off.
Would it be sensible to tack it up in one piece, then if I wish to split it, just cut and add two flanges?
I'll be sure to post photos once I've started!
