The guy you talked to is obviously a complete moron. At the most you will will need some hedman s bends to clear the tranny if your running an auto. After that you can route the exhaust anywhere you want. Also what mufflers do you plan on useing your space is limited.

Re: Long Tube Headers and true dual exhaust HELP

The problem is that getting outside the trans tunnel requires going over the subframe rails at some point, and it destroys ground clearance, but really not as badly as having the header flanges hanging down. Long-tubes and duals are definately a challenge when trying to maximize ground clearance.

Re: Long Tube Headers and true dual exhaust HELP

whoever says it is impossible i did it with hedman 1 5/8" collector headers, mated to hedman S bends then used a Summit universal H-pipe kit, then 2 moroso spiral mufflers and 2 turn downs before the rearend. IT was an amazing upgrade to the y-pipe setup.
