Will this cause boost creep?
Hi Guys i was wondering if these mods would give me boost creep. So far my car is completely stock besides a catback exhaust. If I get a hi-flow cat(saw a good deal on craigslist) would this make me have boost creep? Is this worth changing? I think the hi-flow cat was a bonez one are they good?

OP do you have a down pipe? That would be more beneficial than a highflow cat.
Generally a DP, cat back, and high flow cat will not cause boost creep. However if you add an intercooler and an intake some people report experiencing boost creep and others dont. You will just have to monitor your boost gauge and see.

I have intake, DP, straight MP and catback and spike to around 12-13psi, it isn't a problem as long as you have an ECU that can handle it. I would suggest upgrading ECU to have a buffer zone and less to worry about. I didn't follow this but my boost was only at 7 lbs until I put the ECU in then I immediately went back to 10psi. I will be putting boost up some more soon but it will be a few months. I like having the power in small increments so you get the feel for it instead of wrecking.

^ Yes it is WAY more important. Dont worry about a high flow cat until you have an aftermarket ECU and understand this car alot more than you do. You need to read the stickies and definately search, read, and understand almost all of the threads here https://www.rx7club.com/3rd-generation-specific-1993-2002-16/faq-3rd-gen-other-useful-links-68640/

The downpipe is absolutely the first performance mod you should get. If the high flow cat is something you know you want to do down the line, and this one is a great deal, buy it. The stock cat is a pretty high flowing cat already.
I still have my oem cat, and my car passes smog (CA). A high flow cat will make it easier to fail a smog test.
