Basically, you have the stock cats, right? Think like this.

You have a filter element in the stock cats. The HFC has a smaller filter element, allowing more gasses to get through. The test pipes have NO filter element, so gasses pass through freely.

The cats cause back pressure. Unless you are going FI, you don't want that.

Haven't seen this thread but im also located in Hampton area.

Oh and to comment on your first question here... Yes. I've bought and sold several times. Never had an issue. Not to say it can't happen. But people here seem to be pretty reliable. Jist as long as you can see pictures and they put their name/date in the picture on paper then you stand a better chance not getting screwed. Never pay for anything if you haven't seen it. And NEVER "gift" money via paypal. Spend the money and keep the protection. If you have any questions about a certain member feel free to pm me.

Yo. Feel free to join us on our little mini cruises and coffee runs. I posted earlier that i'm working the details on a Skyline drive. That will likely be in september sometime.

Ok cool you can text me at 248 508 8620 my name is john let me know the place and dates you guys meet up.

If you know them, gifting is great. Just don't do it with a stranger lol.

Ah ****. there ain't enough room in this group for two John(s). :icon17:

**** that. I wouldn't gift you a dime. :eek: ;)

How many z's usually show up?

Largely depends on who is in town. Last cruise we had seven because two, I think, were on deployment and one was ill. Could have easily topped 10. Typically about 5-6.

Well hopefully this John isn't a tool like our Z-leader also named John. (Jj, He's not a tool and he's not our leader :stirthepot:)

John, welcome. Nothing fancy, just some guys/girls who love our cars. Hope to see you next time we hang out.

Tigger - when's the next drive? I know you have something good for September, but I'm sure we can get something in this month.

Thanks for the advice guys. I went ahead and ordered resonated HFCs and G3s to go with my CF FI exhaust.

Awesome hopefully I'll be able to make the next meet how many nismos are there?

Just one. His name is Adrian. He, too, is a tool. :stirthepot:

I'm on travel pretty much until september.id-september. And i already have plans the weekend i get back. Y'all should go ahead and get something together without me. Suggestion? Another run to Weeping Raddish. That was a fun day (when they were open). Avoid the cops. Lol!

I beg to differ with one of those comments.... :ughdance:
