i think you need a custom DP. that and a GST muffler to go the cheap way.

You can, infact the HRC kit requires you cut the stock downpipe and a partial DP comes with the kit which clamps to the stock one where you cut it. If you aren't going HRC, you will need a custom downpipe. Also, if you check HRC's site, they mention that for the stage I kit an exhaust is recommended but not necessary. I ran mine for about a year with the stock exhaust. I did notice high egt's near the end of a long pull though which was helped out by an exhaust. I also gained a quicker spool up.

Short answer yes, but it's better to have an exhaust b/c the stocker is very restrictive.
