I have a set of Hyper-flows on my car less than 300 miles...considering going to test pipes with O2 extensions.....hmmm might see a sale or trade in the near future
Superformance has them brand new for ~$475. I picked up a set from them for my 348 and they look nicely made.
Thanks bro, capristo.de have a pair for 409 EUR (475 USD) but somehow that converts to 880 USD by the time they reach the US. I wonder if they would ship direct to Canada.
I think you guys MISSED the thread where INTMD8 built his own hi-flow cats. He made a jig, which means he can build any of you test pipes/hi flowcats. He can also build them out of 321 Stainless Steel, which is not even offered by any of the after-market ones Ive seen. Lightweight and good heat retention. I'd send him a pm .
