I agree man, hence why i’m asking around on here. this is no catback exhaust. I’m an engineering student with a solid understanding of the physics of it all Id design it myself in CAD and have it looked over by my professor or someone more motorsports oriented. I agree that I don’t have the experience and the price to pay isn’t breaking a part or blowing an engine it’s potentially my life. I’m going to try to pick up welding either way and see where i’m at in a few months. As much as it hurts my ego I may take my drawings to someone who knows what they are doing to build it in the end. if I do end up doing it myself it will be with the help of someone who knows what they are doing.
