anyone who uses crush exhausts are dumb as shit. everyone knows you want mandrel bended for proper air flow, crush ruins that airflow and effects performance.

If the exhaust manifold stops you from putting on the exhaust normally, why not edit the manifold to make the rest of the exhaust easier? dee-da-dee?

@ProjectCarTV Its that fucking faggot Doug! I hold him responsible! Im not gonna view these bullshit videos until they fire that asshole bitchass!

@expervillage - Crush bends? REALLY? A video showing CRUSH BENDS is on Expert Village? REALLY? Who is responsible for this garbage being put on on here?

Crush bending is for companies that don't care about genuine performance.

@IvyTechMark i saw something on a show once that the put the pipe in a machine and they shot water in it at about 4000psi and it straightened it back out for the most part. the sand might would be a good idea to try but im wouldnt garunttee anything.

Im so interested in making a great sounding muffler but i dont have the money or the tools

@plantboy2221 so the retard who buys a crush bent 2.5 inch exhaust from ebay gains like 2 hp where as the smart guy who buys a legit skunk2 (or any other reputable brand) 2.5 inch mandrel bent makes 10 hp, yet it doesn't really matter....... there is a reason why ebay built cars end up slower then cars with legit parts in them, your paying for quality and the know that with more parts, you wont suffer in the end because of 1 badly made part.

@bastec666 That only makes a difference on short radius bends which he's not doing. On a stock car we are not even talking a couple of horsepower difference. Dyno proven.

I have the same Huth bender. Can pipe be filled with sand, etc. to prevent denting and make it look more like a mandrel bend? Mark from Ivy Tech Community College.
