I have read alot about the Joe Z exhausts and cat backs in general and searched the forum but haven't really found an straight forward answer to my questions. So apologies if this is already up somewhere.

I'm about to purchase the Joe Z PTS exhaust for the ISF and was primarily concerned about passing Texas state inspections/emmissions. From what I have read you still pass because the primary cats are still in. Does anyone here have the exhaust and have passed both the emissions and visual test?

Also does installing high flow cats to replace the secondary cats have any benefits/drawbacks? Performance wise and from a legal standpoint?

Thanks,
Mike

I believe it's fine as long as there's mufflers and the system doesn't set off the CEL. Not positive though.

It wont set off the CEL because of where the 02 sensors are placed. Seems like multiple people confirmed that.

I've had the Joe-Z exhaust for about 2 years now and I've never had problems with State Inspection. I've always done State Inspections at Sewell Lexus... no problems.

Oh.. by the way, the Joe-Z is a must have for the F!!!

NTXISF

I'm glad to hear that. I feel alot better knowing someone else has passed. Definitely can't wait to get my Joe Z.

Has Sewell given you any problems with your warranty for all the mods? Thats where I bought my F.

Good to see another F in Dallas! I don't see too many.

Sewell has never given me problems! In fact, they love when I bring the car in for service because they like to hear the exhaust!

I've finally forgot about getting exhaust for my Fsport then I see this thread and makes me want it again! Ugh

NTXISF

where did you get your exhaust installed? any recommendations?

I have the ISS Forged exhaust and also have passed every time at SEWELL. I got my exhaust installed at Pronto Muffler in Plano. Great service and they know what they are doing.

I had my Joe-Z installed at JP Importz a couple of years ago, but I don't think I would go there if I had to do it again. I would try Cains Autohaus in downtown Plano. The owner Daniel is really a stand-up guy, extremely trustworthy. He does really good work!!

NTXISF

how do you like the ISS Forged for everyday driving? Is there any drone?
