3.5'' exhaust DIY or NOT

[robo]

It looks like for my gt35 I will need to have 3.5'' exhaust made up, the question is do I try to get it done my self or get professionals do it for me?
Me and my mate Pete have some skills of making stuff so hopefully between us should get it done.
Did you have some bad experience/ trouble on the way of making your own exhaust that half way down the road you regretted spending money on pipe, gas and wasting time?
Would anyone have idea how much would 3.5'' exhaust cost? The last time I had 3'' exhaust done at long life it costed 1k.

Cheers

i am almost sure that with a full 3" system you will be ok

also fit a scremer pipe to help

Robo,

I made mine turbo back, its not that hard to do. All in it cost me about £300 that's including a new 3" straight through back box..

Have a go..

I would DIY it as long as you have the tools to cut the tube accurately and you can wield a TIG torch

Time and patience obviously, but making exhausts with hacksaws is ********.

This would be so much easier if 3'' could be enough. Few years back when I was building the s2 I bought some 4'' pipe and that was very tight.

Do it DIY, it's much more satisfying, even if it's time consuming. I was getting quotes of over £1000 for a 3" system for mine so I bought a TIG welder, chop saw, belt sander, tube, bends and gas and still came out with plenty of change for £1k.

I made a 3.5" downpipe for Jamo's car and it's tight but doable.

Got the Tig, couple of grinders, sander just need to get chop saw for metal as I dont think I can use my dewalt wood chop saw

If you're going to do it, one of these is really useful

Not too long ago i had 3" system made for my coupe £500.I used MIJ Engineering Walsall.They was really good

I bought a TIG and all the pipe and bends from MIJ. One straight through box and a side exit if you want to avoid the tricky bit over the rear driveshaft. If you have access to ramps it will be a whole lot easier than doing it under the car!

Sounds nuts, but draws a little too much attention
