Default X-pipe and Some bullet mufflers???

Ive done some searches for some pics and found some but they all dumped before the axles. Anyone have a pic with an X-pipe with duals going to end of the car? (was going to take the pic to the muffler shop in case he has any questions?)
My ORY has some buildup where the "Y" comes together and instead of replacing the Y, was going to go with an X and some duals. If i JUST replace the Y would there be that much of HP difference compared to an X pipe and true duals? If its only a HP or 2 im not going to do it (X&duals) ifits like a 10 or 15 then i think it might be worth it. Let me know what yall think.. thanks!

when i went from hooker the hooker y pipe to an xpipe with duals, i gained 17rwhp and 17rwtq. This is not the normal gain, but it is what I got with nothing else on the car being changed. PM me for more details.

More details.. I got one of those bad ORY's from pacesetter.. Where the Y comes together its got a bunch of overhang/buildup. So, was wondering if just to replace the Y with another one or get the X with 2 mufflers? Let me know more...

Not sure if you can go over the axle with 3" pipe, maybe 2.5, it would be close...

If you can afford the duals, go with them. The peak HP gain shouldnt be anything to write home about, but the power under the curve will definitley increase.

you can sure feel the SOTP difference with the x over the y, but mine dumps before the axle, I don't know how the over or under the axle setups behave.

ls1speed.com has a picture on their website. 2.5" over the axle is optimum as 2 3" pipes is too tight , especially if lowered.

See if you can get ahold of Slyws6 he has a 2.5in. x-pipe setup with bullets that run under the axle out the back.
