Re: Re: refinishing muffler and negatives with no cat?

I was able to reach all four flange nuts with a long extension (I
think it was 12") from the front side of the cross member. Turned
without a cheater. 

This weekend I was able to compare my gutted converter against a stock
exhaust system. No comparison. Even if less efficient than a straight
pipe, is a gazillion times freer than factory. Is MUCH cooler too.

Re: fuel economy -- try mistiming your vehicle (the notches on my
Volvo block aren't labeled -- thank goodness I FINALLY stumbled across
page C:05:03) and compensating by cranking up the fuel mixture. Drops
to 13-14 mpg.
