Building a custom exhaust in the garage...
So, the problem I've always had with my car is that I always bottom out on the exhaust system. Reason being that it's a 3.5" diameter pipe. I got tired of scraping all the time so I decided enough is enough. I've been practicing on my new welder for a few days now and my new oval exhaust piping just came in as well. Don't be dissin' on mah welds, I just got the machine 3 days ago 
I'll get it mounted on the car and I'll be welding on the v-bands tomorrow.

This is what you gotta do when you're too cheap to buy mandrel bent pipe
This oval piping is expensive as is already, the mandrel bends alone are priced way insane!
Side by side shot of how much difference in thickness there is between these two.

As for the flow, I honestly don't think it's going to be much of a restriction. The pipe is huge lol, and even if it did affect the flow a little bit, I can live with myself since I saved $175 by not buying the mandrel bends. It really is that expensive!
If I was better at welding, I would cut them pipe section into 4-5 pie cuts instead of just the 2 that I have. Doing that would basically angle the bend just like a mandrel bent pipe.

dude..u should patent something like this and sell the kits..people like me need exhaust clearance! i jus dont kno how u would explain the diameter of the pipe for people who want certain sizes and etc(like what is it equivalent to in terms of a normal round exhaust?)..interested to see how this goes..gl bro

As far as oval vs round goes, it's all in the cross sectional area. if the cross sectional areas are the same, then theoretically, they should flow the same. Heck I'm waiting for someone to make a star-shaped pipe

Show me some penny-stack welds Jeff!
Glad to see you got a TIG welder... should be much stronger than the MIG welds. I had a chance to do a little welding with a MIG and TIG when my friend and I were fabricating some custom pipes for my turbo for my Mustang. Needless to say, my welds came out very blobby and ugly.
