ok, i was lookin at the jet hots for my 97 formula, and i look the looks of them, and i hear the coating is awesome, won't rust.

now my question is....

this obviously can be bolted onto my car, but if i got the GMMG cat back system, would it fit??? and would i need a new y pipe, or make any rear O2 sensor and custom tune it changes???

 

Yes, Jet Hot Longtubes are extremely nice... it's what I have.

Yes, the GMMG cat-back system will indeed fit. Any catback system for the LT1 will. The issure you have to decide on is how you want to link the headers and the I-pipe on the cat-back.

Usually, a y-pipe is made, which can either be custom (best), or there are pre-made solutions for you to buy, however, they don't have a great fitment record.

As far as O2s go, since you have a 97, you will need to get FLAT connector O2 extensions for the front, in a 24" size. You will then need to either purchase O2 simulators for the rear O2s, or get your PCM tuned, and just delete them (what I did).

 

What he said is about right. With a Y-pipe (The hooker Y will fit, or come damn close to it) the end of the Y will come out a foot father back then the front of the catback (you cut the catback to fit). It will weld right up, or you can put on a flange and bolt it together.

You'll need a 24" extension and a 12" extension. I used 2 24"s since that's what I had. The extra length doesnt hurt anything.

The rear O2s have got to go, pick up some O2 simulators. The front O2s will screw into your header collectors.

 

Yes it will fit but you will need a custom Y pipe made. Just use O2 sims for the rear O2 sensors and your set! Its one pricey setup, don't ask me how I know
