exhaust smell while driving....

Thing is i notice it with the windows down, cant really do smoke test with em down. will check the body plugs @ lunch. i re adjusted the trunk last night & did the paper trick (for drag) to make sure its even tutching the seal along the bottom. & it is good to go now but still has smell with even drivers side window down only. are the tips soposta stick out a little with the hipo exhaust? wish i had a smoke machine & wind tunnel to barrow lol!
