Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!
If you have any problems with the registration process or your account login, please contact us!
After installing my longtubes and ORY to go along with my DMH cutout and flowmaster catback, I have been wanting to get a good video for some time now. My room mate got his hands on a G-tech accelerometer for the day so we went out and had some fun.
Very nice. Hoping to do headers and Y-pipe if and when I've got the money and time. Probably next spring after school, then back up for the summer. Thinking on BBK's from Summit because they're cheap and ceramic coated. How much does the cutout help it?

If you run a Flowmaster a cut-out help's big time.
If you run a Borla or something similar then it's just good for noise
I've seen this proven with 2 cars I worked on from this site.
But Flowmaster has a really nice sound
Car sounds very good Brett.

I bet with the cutout though you're making more power in the upper rev's. I read a thread before over at thirdgen about exhaust backpressure, it said that all it does is retune the power curve.
The cutout made a huge difference for me with the flowmaster. Here is a dyno graph from this past fall, cutout closed then open when all I had was a lid and cutout.
