I got 2012 Toyota Hybrid Prius. I get a random, intermittent thump at the bottom of the right front passenger door, at the bottom. Maybe as low as the rocker panel at that low location. It sounds like a rock thrown up into the wheelwell by a tire, but the thump sound is not that location. Sometimes it sounds like when a metal gas can that is left in the sun, it mite buckle and create a sound. There are no moving parts there. The dealership is perplexed. Any ideas? Thank you

I own a 2003 Prius 4 Door Sedan that is in excellent condition with 155000mi on it.

Trouble is, thieves literally tore out nearly my entire exhaust system.
The other trouble is that I did not have the type of insurance to cover it's replacement, and I am disability retired with almost no financial resources to to afford a OEM or OEM style replacement system.

I intend to be a lifer owner of this car. I love it.

Having been a master auto and motorcycle tech for over 40 years, I have designed an affordable replacement system that I can assemble myself.

It will be missing no OEM sensors, but will be only running one brand new ODBII catalytic converter (I just purchased at $57) that outlets to a straight 1.5" mid-pipe to the muffler pipe. It will be missing the secondary Cat and its heat valve system. It will be missing the Resonator. (I will consider installing a resonator if the system is too loud with out it)

I have done careful research and in my state of NH this system will pass inspection because it does pass the federal muster of requirements. And No, I know it will not pass CA or NY CARB requirements (though I am almost certain it would pass their emissions wand)

Here's where I would like some comment and advise. I would appreciate any helpful response.

As designed, is there anything about my exhaust system assembly that would throw off any of the computer systems diagnostics?

Have I overlooked anything that would effect good run-ability?

This car has been well maintained quite trouble code clean all of its life, except for one recent Hybrid Battery voltage code that I solved by recreating clean terminal connections on the rail to the individual cells.

I suspect that with out the second Cat and it's heat valve system I will have to warm my Prius up a little longer for the cat to get to functional temperature.

There might be a slight back-pressure difference without the resonator, but will that very slight, if any, difference trigger any trouble codes?

Thanks for reading this.
I will appreciate any of your feedback.

I have a 2002 Prius, with 255650 miles still running real good, and everything works good!

I have a 2011 Prius with the original hybrid battery that will hit 326K today on my commute to work...... No repairs the last 2 years other than quarterly oil changes.....
