So I've been doing some searching and reading for alternatives to an oval pipe. I've made oval pipe before by ovalizing it in a shop press. I'm looking to do something a little cleaner (other than actually purchasing it).

A little history on the project...I'm running a 3.5 inch downpipe on the driver's side and I want to tuck it up as high as possible.

I've come up with the following ideas:

1. Make a fixture and ovalize 3.5 inch pipe in a press.
2. Run two 2.5 inch pipes in parallel
3. Rip a 2.5 inch pipe along its center, and weld a strip of 2 inch pipe in between the two halves.

Opinions?

 

Hmm,#3 seems easier to me to make but time consuming

 

Its not that expensive.

 

Seriously. Run oval tube. I think it will be comparable in price to running parallel 2.5s.

 

I should have posted that I have tons of 2.5 pipe and bends as well as straight 3.5 tubing already.

Thanks for the input everyone.

 

Is this for boost pipe or for headers to turbo pipe? If the later do yup really need 3.5 inch cross sectional area?.....
