Hello everyone,

I am a newbie here and a new mustang owner as well. I just bought a 2000 V6 Mustang and it's the first muscle car I've ever owned. The car is awsome and I have nothing but fun driving it. But now I need help with something. I am planning to do some mods to get what everyone wants out of there V6 MORE POWER! LOL so the first mod I did was a CAI from american muscle. That didn't satisfiy me thurst cause I couldn't really tell any increase in power or performance. The other mod I wanted to do was to put dual exhaust on the car also. Now here is my problem I have been doing research on the net now for about two weeks trying to figure out what the best kind of exhaust would be to get. I am not talking about namebrands here. I am talking about styles of exhaust kits that are available for our cars now. There is a standard conversion kit available that bolts up right at the Y pipe and then there is the version that Pypes I believe is the only one that sells the whole complete kit that goes from the manifolds all the way back. That kit includes the X pipe and all. My question is which is better I assume the Pypes kit must be because it costs way more but you are also paying for the name as well. I want a good rich sound but I am also looking for more power as well. But if there's not that much difference in hp gains between the 2 kits then I would rather spend the money on the Y pipe converstion. Only becuase I can get it about 350.00 dollars cheaper through summit racing. I just want to know what the main difference is between them. Thanks

i actually have the pypes kit where it bolts to the y-pipe.. and let me just say i wish i had gotten the full x-pipe kit with cats.. the problem with the y-pipe kit is that it still retains the restriction that your stock exhaust has since its still forcing all of the gases down into one exhaust pipe.. the sound greatly improves.. however i think it could be better.. are you trying to do this all yourself?

You won't see a substantial gain, with just the exhaust alone no matter which one you choose. If money isn't an issue, then a cam and head swap with the exhaust along with a dyno tune. Which you would have to do anyway. If you want to hear what the two systems sound like, go to ( MustangExhaust.com ) and put in your car then pick the system. They'll allow you to listen to 10 different systems for your car, that is if they make what your looking for. Good luck, Mike. SCT Tuner.

the only thing that i can think of thats a great power gain that u want is a supercharger or a turbo...and if exhaust prices are an issue then idk...right now i would go with an exhaust, udp's, 3.73's or 4.10's, and an sct tuner...that would get u started pretty good....but if i did exhaust it would be true dual...it just sounds and feels soooooo much better. the y pipe really doesnt help u out with power at all...

Thanks for the response yes I am going to do this myself. I'm a pretty good mechanic and I don't foresee a problem with doing the mod as long as no welding is involved. I can't afford a supercharger right now though I wish I could. I do want to get udp's but I heard that they were a waste of time and money too. If someone has any info on this as well that would be greatly appreciated. So How much hp gain will I get installing a Y pipe exhaust mod and how much hp gain will I get installing the X pipe mod. Thanks

[Markstang690]

honestly i have no clue how much you might gain with the y-pipe vs. the x-pipe.. the x-pipe is definitely more.. the y-pipe is much less.. to do either of these all you will have to do is cut/trim them to fit.. neither require welding.. if i were doing this again id spend the extra money on the full x-pipe kit.. just my opinion though

ya the y-pipe will give u very little...i mean VERY little hp gain....and if you put on some 42% udp's your freeing up 15 hp or so..idk i think its worth it...unless ur running a crazy sound system then dont buy udp's...and sometimes u can get an h-pipe which can be cheaper and still gives u an increase in hp, but not as much as an x pipe...but its all up to your sound preference too...the X is a little to raspy or sporty sounding for me. good luck...hope you find what u want.

Most people around here seem to prefer the sound of an H-pipe on the V6 compared to that of an X-pipe. Just know that there are pros & cons associated with each. Typically, the H- will produce a deeper muscle car sound, but won't produce as much HP/Torque as an X-pipe. The X- will provide better exhaust flow (i.e., better performance increase), but you won't have that low deep rumble as with an an H-pipe. I wouldn't recommend the Y-pipe conversion kit you mentioned earlier. If it's not a true H-, X-, or divorced set of pipes, you're selling yourself short.

I switched to Magnaflow mufflers & upgraded my dual side-exit exhaust from a Y- to an X- 2 weeks ago & I'm lovin' the feel & the HP increase. The sound is a little bit subdued now, but I haven't gone WOT yet. So we'll see. A 8.8 swap with 3.90 gears & a tune is next. I can't wait!

H-pipes make a great low deep rumble, like a muscle car should +1

theres no way udp's free up 15 hp.. i think a pypes x-pipe with pypes mufflers sounds great as if they engineered the mufflers to reduce that unwanted rasp and all that

i dont mean 15 to the wheels
