My question is this:

On the 3.0, does it make a difference in exhaust flow, or actual Internal Diameter if the pipe is crush bent, or mandrel bent?

Would I still loose too much power with a 2.5" crush bent exhaust, or does the crimping in the bends effectively lower the ID?

Thanks guys!

I'd take 2.25" mandrel bent over 2.5" crush bent any day of the week.
Crush bent pipe has awful exhaust flow characteristics.

Which begs the question, is there a 2.25" mandrel bent system available for the 3 slow ?

I have not found one yet...

I went to a local shop and they quoted me $175 for a 2.25" system with a flowmaster (back when I wanted one) and a chrome tip. Another $100 for a dual exhaust. You may just have to get it custom made.

I'm pretty sure there's some mandrel bent systems. I believe the Jardine system is mandrel?

And I know crush bent doesn't flow as well, but the 3.0 probably won't gain much, if any power, from any kind of exhaust work, whether mandrel or crush. Also, knowing that crush doesn't flow as well, would it alleviate that at all going with a larger than normal size (ie 2.5" over 2.25")?
Thanks!

i've looked too, but no luck on a 2.25" mandrel bend exhaust kit for the 3.0 as far as i can tell...

personally, i'm going the custom route.

Jardine has a 2.25" mandrel bent exhaust cat-back system. I have it on my 88 and I'm pretty sure they make it for the 2nd gen as well. Performance Products sell it and when they run a 10% off special it's not too bad of a price.
