just finished installation of magnaflows stainless dual out catback on my '07 h3. fairly simple install,as it took me just under 2 hours on my garage floor! i was able to remove the old exhaust in one piece so that helped alot. have to say i am very impressed with magnaflow's quality and fit, very nice. sound is good, nice little rumble. inside noise barely changed. compliments my true flow intake/filter kit nicely. will upload pic when i can figure out how to alter size to fit. overall very happy, especially with price. $450 shipped to house. oh yeah, forgot to say the kit says its for the 3.5 motor '05-'06, but it fit on my '07 just fine!

i can feel a low end improvement. accellerates better from idle. wife noticed it also. i can also feel more power up top. i let a buddy of mine drive it, who happens to be a chevy mechanic, and he was impressed with the 3.7 power.

Hey Hotrod,
How's the sound inside the cab at 70 mph?

not bad at all, very tolerable. i have had either duals, flowmasters, straight pipes or some form of custom exhaust on everything i've ever driven, and i would say this is one of the more mild ones. hope this helps.

Oh so nice! I am thinking about this Magnaflow and the Borla. I am just worried about in cabin droning! Sounds like your happy. Thanks for your input.

I've got the Magnaflow Catback arriving on Martch 20th!
Looking forward to the split exhaust, looks very sharp from the rear and should sound really nice. I've heard the Magnoflows aren't too load except when you really get your foot in it.
hotrodtom. any tips on installing the exhaust? I've never done any exhaust work before.
thanks,
Raymond

raymond,
start at the two studs by the convertor, work your way back. you will have 4 rubber mounts to pull free, can be a little stubborn. once exhaust is loose and hanging, jack up rear so the axle droops about 4-6" and you will be able to pull it out throught he back in one piece. just watch the hangers so they dont get caught on brake lines, vent tube, etc. it was kinda nice being able to slide under it on a creeper with all four tires on the ground. let us know when you have it done.

use a little WD-40 on the hangers, it will make them easier to slide off the nubbins.

Looks sweet, I was wondering how the tips fit back there, looks nice.
No rattles or banging?

surprisingly very tight, considering there is only four rubber hanger mounts from cat back!

Hotrod, the email you posted is not the right one. Would you check again and repost. I really want to buy the magnaflow system at that price but I have not been able to find it anywhere for that cheap.

sorry about that. i would say search ebay and shouldnt have any problem finding in that price range.

My Magnaflow cat Back arrived yesterday. The installation guide recommends cutting the stock exhaust right behind the middle muffler. I'm like WTF!!
So I crawled up under it and indeed it is a one piece system behind the front flange. I was wondering if it was possible to pull it out in one piece, looked possible but wasn't sure. I don't want to cut the stock exhaust in half so I'll follow your lead on starting at the front and jacking up the back to open up the space between the axle and the bottom of the chassis.
Can you tell me where you placed the jack to lift the body and not the axle?? I'm not at home (on the road again) so I can't check. Seems like there's a scissors jack for the axle or is there a lift point on the body? I've not read my manual that close, sorry.
Thanks again for the tips. I was looking at the hangers and the nipples on the new exhaust. I was concerned how hard it would be to get the stock hangers off the rubber mounts, they look dang tight.... any tips on removing the hangers other than some astro glide and WD40 and tugging really hard??
I'll probably install the Magnaflow this weekend. Get some pics up if I get the thing on, the quality seems really nice and the chrome engraved tips are too sweet.

I put the jack on the frame in front of the passinger rear wheel. You won't need to lift the rear wheel of the ground.
