FS:CA:4A-C Square Tube Header

ok so heres the deal. i just finished a prototype header for the 4ac useing square tube and still retaining the stock crossver pipe. id like to start producing these headers so if you live around riverside,ca and are interested in headers for your sr5 post here. price should be around 150 ish. if theres enough intrest in this then i might continue producing these at a lower cost . currently 2 spots open so far. and yes i do know that they look verry rough, however this was my first attempt and my personal prototype and installed on my car. so post feedback plz

I edited your post topic to include FS, but thank you for including the location.

wow a very good idea, are the runners 2 exhaust valves each or does each exhaust valve have a runner? do you think the flow is good? did the sound of your car change? sorry for all the questions

no prolbem. if it wasnt for questons then people wouldnt know. well it is a 2-1 design so the ports are not separeted. it feels like it produces more tourque as well as a nicer rumble fromthe exhaust however it is more noticeable because im straight piped. and as far as flow i think it flows just fine. before instalation i ran some air through and checked to see the flow

Why the square tube instead of round?

props to you. i would like to see a pic of it off the car, and maybe with a coat of paint.
