Default Magnaflow questions

I just ordered my Magnaflow Single Tip catback for my 02 WS6, just wondering what kind of sound i should expect with longtubes, ORY, and TR230 cam, and other supporting mods, and if anyone knows around the hp numbers it should pick up from a crappy cramped chambered exhaust with a turndown. O i have another question if anyone else is having problems with O2 codes saying low voltage and you have 02 extensions and how did you solve them, any help is appreciated!!!

It will sound great...i love the magnaflow, always had one on my vehicles, they flow great. My cut out only picked up like 6hp over the magnaflow, then i went w/ one of the short "race" mufflers that are straight through louder than the cat back, but quiter than the cut out and made the same as the cut out.

ive got pretty much almost the same cam as you with pacesetter longtubes and ory and magnaflow and it does sound good. honestly, it is still pretty quiet. your TR 230 cam with a 111 lsa will have a nasty lope. the sound of magnaflow id say has a smooth crisp sound rather than raspy sound that people say.

to tell you the truth the magnaflows are pretty quiet, especially inside the car. i have a fully built 408 with kooks LT's and ORY with a magnaflow catback. outside the car it sounds nice and its decently loud. but when your driving, it sounds almost stock to me. IMO, it just hides the aggressive sound of the motor. I wish i had something more like a borla or corsa, something loud and aggressive. but thats just me.

The setup should should great. I loved how my LT's and magnaflow sounded. Its quite under 2k RPMs. After that it can get pretty loud.

I recently had a magnaflow bullet welded into my i-pipe as I wanted to get a deeper tone. I should have the car finished this weekend, so I'll see what the sound difference is.

I disagree with fitment. It was probably one of the best fitting slip-fit cat-back systems I've installed on any car.

Not mine I had to cut the pipe from the muffler to y-pipe because it was too long and one of the welds that connected to the hang broke.

I didnt like the sound of my flowmaster but it bolted right up no issues.

So did you end up dumping the exhaust after the bullet? How much of difference is there between the bullet and the catback setup? (as to sound not loudness)

No. It still goes into the magnaflow muffler after the bullet. The bullet I put in is intended to reduce and high end pitches further and make the sound a bit deeper. Its a straight through design so I don't think it would reduce the volume to much, but we'll see when I fire it up this weekend.

Thanks guys for all the help, i am debating whether to cut the old catback off and run open Y pipe till i get my magnaflow but i dont think anyone where i live would like to hear it crank at 6:30am, but i dont really care for my neighbors anyway so what the hell i think i will cut it, would i see any gains if i installed a QTP electric cutout along with the magnaflow system
