exhaust Q

[padge]

if you were to make your own exhaust by buying pipe in sections, what angle/lengths would you need? not including the downpipe.

[Piggy]

I think you would need to layout a std exhaust and measure it all mate.
bit of your time and a pen/paper and tape!

I know dum dum has done it, but he used 3" bore

I think Jonny has made a couple now, he would be the best to help :p

You need the following (for an estate, assume the same for a sedan?)

2m straight pipe (you only need 95cm IIRC for the main centre section, but it's worth having the spare for the back etc..)
1x 45* bend
2x 60* bends
1 15cm flexi section
1x welded 90* tight radius bend (if you have a tdo4 or similar with a side facing exit)
a backbox of some sort.





Top one is off my estate with a rear exit GT20, the bottom one is off Carl's sigma TD04 XUD

[c.gerrard]

Thought you were having one made up?

I think all you would need would be two 60 degree bends and we could only get the straight pipe in 2 meter lengths with some left over, so not sure exactly how much you would need.

I'd double check the angles, as I can't remember exactly

[Jonny81191]

My list is correct, just checked the part numbers

It is also worth buying a mandrel bent 90* to chop up to make small bends where needed. or if you're not that fussed about flow you can just cut pipes at an angle.

[padge]

I only want it from the downpipe, as I already have a downpipe made, just need the rest onwards to the back.

[Jonny81191]

In that case, 2x60* bends, about 1m pipe, and a box.

[padge]

don't want a box so 2m pipe, how much of the 60* bends will I need?

[Jonny81191]

Erm, all of them? as in both?

[padge]

length

[padge]

just to clarify, standard xud exhaust is 2" right?

[martyn92]

Think it goes less than that in places.
How much did that cost you roughly Jonny?
