Description:

I know Thunder Racing made these years ago (for those who remember those guys from Louisiana)... So I have the Supermaxx with high flow cats. I bought it when it first hit the market back in like 2004. But before I say "f*ck it" and just hollow them out ( in case I'd ever need them again with my luck).. I'd like to find the off-road inserts. Years ago Thunder sold them for $150. I needed cats at the time so didn't think to buy them under that , well in case ' factor. But 15 years later.. That factor has came about. Well, more like long ago, as in a few years of buying the Supermaxx system. Since AIR Pump has been long gone removed, who knows what long term damage really would happen to these high flow cats also.

I'd hate to have to buy their cat-less y-pipe. Or make from scratch... But I cannot find them cat-less cat inserts anywhere!

Thanks in advance
