I was looking into getting some high flow cats for a stainless Bassani off road x pipe I am getting for cheap from a friend. I want cats that are similar to the ones that come on the bassani catted x pipe kits, and only stainless.The only cheap stainless steel ones I came across were on Performance Curve.com and they were manufactured by a company called Thunderbolt. Has anyone ever heard of or used these. In the picture and the specs they look good, but $37.99 seems real cheap for stainless steel. And the only other ones were around $150.00. I used to have a bassani catted x pipe on my 96 Gt and the quality was top notch, especially the cats. And the magnaflow cats just dont compare in my opinion. I know I should just bolt the x pipe up the way it is but I think it will be too loud for me, plus I live in cali, and its way to much of a hassle to have to deal with. Any help will be appreciated.
