    Best High Flow Cat For 85 Eldo?

    Hi all,

    The past six months I've had a straight pipe on my 85 Eldo and I keep getting sick from the smell. I thought it would be an ok conversion, but I guess not. So what kind of high flow cat should I put on? And do the high flow cats require high flow mufflers, or is that just an added bonus?

    Magnaflow sells high flow cats through summit and jegs and what not. I'm sure they have some cheaper generic ones as well. My 2000 Mustang GT has a magnaflow x pipe with cats and it seems to work fine now for few years.
