i have a stock ls1 i was going to go with long tubes to y pipe to mangnaflow to 2 cutouts off the headers or go long tubes to x true duels what do u think would be a better also does any one no how much hp you loose if u do true duels over the Axel vs getting dumps off the x pipe thanks

Im getting my LT's early this week and i will put them on with my magnaflow catback and ORY pipe, ive heard sound clips and it sounds pretty good!

I think the losses of over the axel vs dumps would minimal as its so short and with duals you as basicly doubling the cross section of pipe, dump imo give better clearance on axel travel and the reverb off the pavement and bottom of the car making it seem louder.

i would go duals. As long as the over the axel setup is full mandrel bend than you should loose very little hp. If it is non- mandrel bend over the axel than the difference will be much larger.
