Re: magnaflow or flowmaster

I may be wrong but did a search for a 60 series Flowmaster that would fit your car and could not find a 1 in 2 out cross flow design. I believe 80 series is the only one that "Flowmaster" makes for our cars .If I were you I would call Flowmaster and ask. Hears there number
1 800 544 4761 or 1 707 544 4761

Re: magnaflow or flowmaster

I was curious and called Flowmaster.I was told buy their sales technician that the 60 series is for imports and the 80 series is the only one they make to fit your car. By the way I have a American Thunder 80 series cat back on my car and I think it sounds great. I paid $385.00 for it. By the way i also run a high flow "Magnaflow" Cat.

If it is the 80 series, it doesnt flow as well as magnaflow. But IMO, it sounds better.

Re: magnaflow or flowmaster

I would say the MangaFlow's better than Flowmaster... I have a 30 Series Flowmaster, but it's 1 in 1 out, so they do have a few that can replace that model with that particular setup, but for 1 in 2 out, I think it's just the 80 for our cars too....
