I like mine. Drone, yes, loud and obnoxious, no. Peformance flow thru exhaust let's more air out, together with more sound.

The maganaflows actually take over a 1000 miles to break in, burn off the cutting/machining oils, and stabilize in tone. After those first 3-4 tanks of gas, they sound great.
At 50-60, you don't really hear much, at 75, the sound is there.

 

Just got my MagnaFlow and Airaid installed, both within five minutes of the Fedex truck pulling away! Took about 45 minutes to install both. I've driven it about five miles so far so I can't comment on 'the bad' but damn does it sound nice. I purchased mine through ebay, $460 total. The Airaid was an ebay find too at $180. Next on to the torsion bars and tires. Then ????????

 

Then--- PCM for less maybe??

 

Nice H3 mate and welcome to the Magnaflow club, I see your into the Bling Thing well done I have not seen a red H3 with as much chrome as you have "looks great". Keep us posted with anymore mods you do. Im off to Brisbane this weekend to drive a Supercharged H3 5cyl, this guy has made his own kits and is getting 296hp at the wheels (437hp flywheel) cant wait to drive it and if it looks like a reliable modification I will be ordering one.
