Ok so my 01 sounds much better now. I just installed the magnaflow cat-back. what a nice look and sound. I did install the dual set up (V6 model) on my I4. The only mods to the car for the install was

lenghten the mid-pipe 2in
weld 2 hangers for the other side.

nice clean look

I actually just got a MagnaFlow catback for my 5th gen accord less than a week ago and i love it! It's the oval muffler, so it maintains a sort-of stock look (nothing stock about the tip, but hey, 4" is fun ) It's got a nice, quiet, low tone under about 3.5-4k rpms, and after that it gets a little more aggressive while still sounding tuned (no raspiness anywhere from 0 to redline, great tone all the way through) The 2.25" SS mandrel bending was also a considerable improvement over the stock piping, and seeing as i live in the northeast, this thing will probably outlast my car due to the full stainless steel manufacture. I immediately felt an increase in throttle response, even though i'll probably be lucky if it even adds 3hp, heh. If you listen carefully, you can actually hear the exhaust gasses 'woosh'ing through the piping :D (and yes, that's not the sound of a leak... I know what that sounds like because it's the reason i had to replace my stock setup) I give MagnaFlow two thumbs up, and you can't beat the price!

 

I got my Magnaflow oval put on about a month ago, and man, I love it, I didnt get magnaflow pipping, I made my own, 2.5" cat-back, no resinator, It sounds so good, I get really cool back fire when downshiftring, and really loud deep sound when I give'R, sound great

 

Did the magnaflow oval with 3" tip, love the sound....2.25" piping. I love it. Sounds great.
