I'm sure it probably does sound better in person. :) I would love to hear a better sound clip when you get the chance.

 

adam,

do u have a part number I can't find anything for the HHR on Flowmaster's site...

-wC

 

All he did was replace the muffler people. Go to any muffler shop and they can put one on. It's not a kit nor is it vehicle specific.

 

All I did was replace the muffler and add a tip as howdy said. Not sure what the part # was. It cost me 140 total. (40 of it was the tip)

 

Do you get any additional HP with the new muffler?

 

I don't think I'd really get any extra hp unless the stock muffler was really restrictive. I drove it really heavy before they put it on and did the same afterwards and I couldn't tell a difference. But I really didn't do it for a hp boost. Thats what a cat back system is for.

 

Glad you're happy with it. I personally won't run a flowmater on anything, they are one of the worst flowing mufflers out there and I've seen several rust through here in AZ, so I can only imagine what it would be like in a place where it actually rains. But if you're happy with it, guess thats all that matters.

 

I put flowmasters on a 350 Chevy El Camino and took them off the next week.
At the time I was managing a speed shop. Worst performance I ever had with that engine.

If you're happy - that's all that matters though.

 

I saw a dyno chart for several differnt cars where they put a flowmater on then a differnt cat back set-up in every test the flowmaster was the worst, plus I personally hate the sound.

 

Too True!!! I'm very happy.
