Alright guys, I wanted to check on here before buying Fast intentions resonated high flow cats on the actual FI website.


Are there any vendors on here that have them on hand so I won't have to wait 8 weeks to receive them?


Any vendors with a better price than $670(w/extra bungs) $630(w/o extra bungs)?


I plan on tuning with Z1 after they come in. The extra bungs are to measure the Air/fuel ratio. Would guys recommend getting them on both cats?one?neither?

 

Go to this thread:

I ordered mine through Next Level. I think I waited six weeks? Not sure anyone actually stocks them.

As for the bungs, check with Z1. They may only use one lambda sensor to monitor a/f while tuning. But the best (safest) bet is a bung on both so you can check both banks.

 

Fast Intentions makes these to order. So everyone has to wait, no one carries them in stock. You don't need the extra bungs because uprev uses the o2 bungs off the headers to read AFR.

 

Thanks for the input guys, I talked to one of the guys with fast intentions and got it all settled. They are ordered and should be shipped in 5 weeks but I'm not getting my hopes up. Just going to get ready for the Uprev tune with Z1 to start the year off right

guess you don't read much?

This product is hand built (in house) to order with a standard lead time of 2-4 weeks. Once your order is placed, you will receive an invoice with your estimated shipping date. Note: The lead time may fluctuate less than 2 or greater than 4 weeks based on order volume.

 

Z1 may possible have some in their warehouse. Best to just email them and see.

And at work, just remember seeing them for sale on the site so no, didn't read the entirety of the listing.

 

What is the difference between resonated and non resonated?

 

Resonators are box chambers incorporated into the exhaust system, which are used to make the exhaust quieter, by cancelling certain sound frequencies. A non-resonated exhaust system will therefore, give a louder exhaust note and a resonated exhaust system, a quieter exhaust note.
