the ones that come with the FRPP kit don't leak, or at least mine don't

I'm just saying that the more connections you have on your exhaust system, the more chances you have yo encounter leakage...
Sometimes, you thinks it's road noise when in fact, you have a few leaks (small but still).
Usually, it's easy to tell... you can see black carbon deposit around the joints.

Ended up jacking up the car and using Quiksteel around the edges of the 2 clamps. Let it sit for about a half hour, fired up the car, and no more leaks. Don't know how long it'll last, but it's good enough for now. The rest of the connections are sealed tight.

Next stage will be just getting it welded if I still have issues.

Thanks guys!

They make a stepped down band clamp that goes from the 2.5 to the 2.25 i was orginlally going to go this way with my exhaust but then just tacked them on the car then took them off and welded them solid. didnt have 220 where i was working on the car. But they do make the clamp you are working for.

When I did my dual conversion, I picked up some 2.25-2.5 adapters from autozone. Clamped everything together with U clamps, out to 2.5" pipe then out to the mid/tail pipes.
Where is it 2.0"?

And the step band clamps can leak, too! just put a little bit of copper silicone where the slider block sits on those clamps and it'll usually not leak.

But I agree, welding is the best approach.
