and its def worth it no doubt about that as the longtubes will set you up for future mods (cam, heads, etc)
same setup i have and it is pretty quiet on the street through the stock exhaust even WOT...the catback is the major choking part of our exhaust...i did back to back runs with 100% stock exhaust at the track with an electric coutout in you I-pipe and gained exactly 20rwhp from the cutout from closed to open went 110mph then with it open went 112...mph...i say have the best of both worlds lt, ory, stock catback with a cutout...sounds insane with it open...or very quiet with it closed

i dunno if it might be a pain or not, i know my car likes to buck with my stock gears so i know you would need some 4.10's and prolly a big stall. also yours is a dd and it might become a pain to you. if the exhaust is becomin a pain im pretty sure the behavior of the cam will. research auto's with t-rex's a lil more. you better start makin some money quick cuz as soon as i buy the new heads mine are comin off and imma sell em with the springs and all......so get some hours in quick.

so i could justify spending $500 now for around 20 more hp, but not if it were only 10.

so i could justify spending $500 now for around 20 more hp, but not if it were only 10.LT's with the slp dual/dual should net you 20+ rwhp with a tune. Could be over 25 rwhp but usually those numbers are again with a good dyno tune but like most people if your going to wait on the tune for a cam install or other internal mods then you will probably see about 20 rwhp. Longtubes are def worth the investment though because they set you up for all your future mods (except if your going turbo)
