Default Longtube question

I have an o/r X pipe that I plan on running but want to keep my stock H with cats for inspections and stuff. Is there a longtube that will fit up with both the stock and the o/r pipe without cutting them?

The stock mid-pipe rises to meet the manifolds, so LT's and stock (uncut) midpipes are incompatible. What you can do is save the manifolds and stock mid for inspection time....or, be smart and get a CARB certified longtube and then you don't have to worry about it. I have JBA's that have the CARB# plate welded to the runner so there's no question. I'm sure other brands have exemptions too.

Will a CARB certification allow you to pass all states exhaust inspections or just california?

I don't know of any state that doesn't honor the CARB certification. Given that CA has the most restrictive emissions laws, they are defacto the Gold Standard. You could check with a few area smog techs to make sure (hint: find one that knows his a@@ from a hole in the ground).

I was on the Oklahoma City (SSN-723) out of Norfolk. I got out at the end of 1995 after spending six years and two months on that thing.

it says the JBAs are 50 state legal but the only set they offer that fits a 05' GT manual with the 3v engine doesnt say CARB on it. Anyone know FOR SURE a set of longtubes that will allow me to pass inspection without cats.

The picture in the ads don't show the CARB# (probably a pre-expemption/prototype photo), but on the production pieces the plate is welded on there plain as day (about the size of a stretched quarter on the #1 runner). If it makes you feel better, you can call them to confirm.

So the JBAs with the CARB have cats on them, correct?

there are LT sets that allow to remove and replace cats, i think they are SLP. although shorty's would make the swapping back to stock mid pipe a lot easier.

With SLP the CATS are on the x pipe, not on the LTs themselves. Should pass emissions just fine, just barely though, with high flow CATS.
