I’m in the market for some exhaust parts and came across these I’ve personally never seen them before ! I wanted to know if anyone else had them and what did you notice !

thank you in advance

These interest me because I like clean exhaust - I live in an emissions testing place and the last catless car I had ('90 RX-7) stunk horribly.

I'm actually hoping one of my 163k miles pre-cats dies so I have an excuse to buy these and a j-pipe.

 

Also, here's very nice units offered by a forum-supporting vendor who delivers excellent customer service:

Says they are out of stock...

 

I would recommend the RV6 stuff all day! ive been running them for a while now and they are great! Richie is a great guy, i talked to him a few times back in the day when i was ordering his stuff, high quality stuff i might add, also i believe it was Mark at heeltoe i dealt with a lot when we were pioneering the first lightweight clutch and clutch kit for this gen,Hes also a really good guy. ahhhhh the memories.......

if you are going from stock pre cats to high flow pre cats you will notice a pretty immediate difference in overall Hp and Tq, if you are going from pre cat deletes to high flow pre cats you will notice a slight increase in Tq at the cost of some Hp, but im happy with the extra Tq to be honest, so ya, ive had both.
