Re: How to - Convert Single to Dual exaust - 07 Grand Marquis
I'm thinking about going DUAL also. I have a 2006 that has the same layout,
dual exhaust to two cats and then combine and go to rear of car to one muffler. Seems to be an easy job for a shop. I am going to ask the dealer about this also and get a price. The only thing I heard about a muffler shop is that the mufflers they give you are not the best.
1997 - headon -TOTALED OUT
1998 - front side swiped - TOTAL OUT
2006 - STILL HAS A PULSE !!!!!!!
