Hiya all,
I was just wanting to know how much of a difference to proformance there is in a 2 1/2" mild steel, aluminised mild steel or stainless steel exhaust system and in having it mandrel bent or just how they do it normally. |

Only difference is a full SS system will last longer than your car. lol
The other 2 will rust out over time. As for mandrel or crushed bends. Mandrel is good for anything greater than a 90* bend (over diffs etc) any minor angles it is mainly just W factor. Cheers Adam

Definately go the mandrel bend rather than the other method. I forget the % difference they crush and restrict the exhaust.
I say get it done properly the first time. |

yes, but the remainder of my post cleared that up. Nice car though mate I was just trying to help you navigate a little better through here. Exhaust technical( or similar) is further down the main page. Give it a whirl in there.
