    Troy re-cored mine in 2020. $1200.00. Dave Helms, (Scuderia Rampante) sent them to him. Dave now has the HyperFlow name.

    I got a pair of high flow cats from Nouvalari and they came out great. I don’t know who their supplier is, but I’m suspect they are off-the-shelf units adapted to fit various applications.

    I would have recommended Larini 200cell cats, but looking at the Testarossa forum, Larini exhaust system sare getting quite a few complaints: Poorly fitting pipes and long delievery delays.

    The nouvalari shipped in two weeks, fit like a glove, and with the strong dollar was very affordable.

    Agree, Nouvalari. I have them on my 95. No problems with a sniff test.

    The issue with fabspeed for 348 is they are not stocked (duh) and I was told 6-8 weeks for delivery. That might have changed. Otherwise, I’m sure they are great too.
