Homemade Exhuast

[asps91]

Hi guys, I'm building my r33 gtr and going single turbo. The 3 inch rsr exhuast I have will be removed to make way for a 3.5 inch system from the 4 inch dump. I am planning to order flanges, pipe, mandrel bends ect and tackle it myself. I have a 130amp mig and a metal cut of saw which will more than be up for the job. And I of course will be doing this in my garage on jack stands so its going to be a tight fit

Out of curiosity how many of you have tackeled this before on their own, and could you guys give any useful advice. One thing I am uncertain of is if I should start from the back and work my way to the front?

I will update this thread with more pics once I start dummy fitting the manifold and dump and starting on the thing.

start from the dump and work your way to the tip as its easy to change the height/ line up of the rear not the front, if you get to it last

Thanks for the tip. One shink I was unsure of was how I go up about hangers. Should I build the exhaust around them or worry about that last? Or should I build from hanger to hanger?

if you were to build an exhaust that is tucked up into the body for clearance i'd do the hangers last if you had a spare jack/bottle jack to get everything in the right position

I haven't done it but I have spent a fair bit of time under cars and I really recommend you get some ramps, it will be so much more stable and reliable than stands. It scares me to think of what can happen - bumped car, freak earthquake and it's all over. Ramps are really handy too, even doing oil changes is so much easier with ramps. I bought a pair off ebay for $30.

Yea, defiantly. I actually use truck stands which can lift just that little bit higher and a lot more stable along with a few cinder blocks under the wheels for some added security. I was actually looking for some car dealer ramps for sometime as well without any luck. Conventional ramps won't give me the height that I need unfortunately.
