was wondering if anyone has tryed this setup and if so dose it sound worth anything at all? looking for somthing cheap and with with a decent sound.

You're going to have to get a 2.5 inch Y in order for it to hook up to the stock manifolds I believe. I ran that setup for a while, had my stock SS catback and stock manifolds. Definitely made the car louder but it was very raspy sounding, didn't really like it very much. Put the money towards a catback instead.

ok ive decicded that setup isnt for me, gonna buy a magnaflow muffler and run it thru the stock exaust piping and have the cats removed. what is the stock inlet on a fbody muffler? 3 inchs or 2.5??

dont bother with offroad y pipe...if you are after sound just get a decent muffler or a catback otherwise go long tubes. my friend had a bullet in the I pipe with stock manis and cats and it sounded very nice. dont mess with the stock exhaust its not worth it..

If your wanting it louder than you do not want mangnaflow.

I have QTP headers with their Y-pipe (use's the flow master Y) welded into the OEM high performance catback. Here's what it sounds like. http://vimeo.com/13286856 It's a little raspy but overall I think it's a good sound. I'm probably going to run a magnaflow here soon just to see if I can pick up some more hp.

I have a Magnaflow catback with an O/R Y right now, stock manifolds as well. Sounds very good, throaty and deep, car has very minimal rasp. You will definitely like it.

I wanted my car to sound a bit louder as well. I went the old fashion way, removing the cats. I ran an LM1 with no cats on stock manifolds and y pipe out back and man it was loud. I then switched to a LM2 dumped still no cats on stock manifolds and y pipe. Sound is amazing! heres a couple vids of my car.

LM1 no cats, stock manifolds y pipe out back.

I've had a SLP Y (2.5") and a Jet-Hot Y (3"), both fitted fine into the
SLP CME exhaust which originally had the stock Y, so they all seem
to be plenty compatible.

Headers are alot deeper sounding compared to stock manifolds, i threw money away trying to make a setup with stock manifolds

OP, it all depends on what sound you are going for! I have straight pipes from my headers all the way to my catback and the sound is great. The only real problem is with pretty much any Y pipe paired with long tube headers, you are going to get some sort of rasp especially with a cat delete. Are you working on a budget? If not, screw a catback, save money and go true duals with dynomax bullet single chamber mufflers. That is my next move even after having a $850 catback!
