I think people don't realize how much time effort and money goes into a project like this. I've tried. I know I underestimated the cost and time it took by DIY'ing it.. But with enough practice, you might end up with skills like this. To make something bespoke and beautiful. Perfect job.
You can buy pipes that are pre-bent, but not like those. Typically they'll be 45 or 90 degrees. The bends he made are actually a series of cuts from a straight piece and then welded back together to form the right angles. It's a "pie cut" because it's made of several pieces. Huge advantage of this is it keeps the inside diameter the same all the way thru, and keeps the walls equally thick all the way around. The off the shelf bends from Autozone/Napa are basically straight pipes (actually tubes) that they press in and essentially crush the inside of the curve to form the bend. That's why they have the ribs on the inner side of the bend.
salut priere de m'informer de la longueur des tubes prsq moi je vais le tenter moi meme sur une tdi deja 'downpiped'. jusqu'a mtn j'ai x4 500mm inox, x4 250mm inox, x1 kit EPLUS Car Exhaust Pipe Control. ca suffit? sinon, j'aurais besoin de quoi d'autre? merci infiniment, j'attend votre reponse monsieur. =)
@@AntoineMk1 nice. Do you put the echaust in any acid after welding? Is there any sense for doing it? Will it last even longer then? What do you think? I will probably build my own exhaust system this summer!
