Borla Exhaust - Parkeeo 2.1.17
System well engineered and perfectly tuned sound for my 2002 TBird. Excelent !! Only one issue at this time. The exhaust tips extend to far out and takeaway from the contour design of my bird. They will have to be modified. Even though we are looking at only 3". I plan to cut and replace with 2 sterling 5.5" ss allen set tips to ensure the length meets the look required. If OK, most likely will forgo welding the Borla tips back. I did like the show of the Borla stamp on them.
Gibson T409 Stainless Exhaust System
Grand Cherokee with 3.7L V-6. The steel is not highly polished (except for the tip). T409 stainless steel is lower in chromium content than the T304 used by some other manufacturers. This keeps the price down. That said, the system is very easy to install. The 4" tip looks good. It gives my V-6 a nice "growl" no rumble. Improves throttle response slightly. I would not pay the extra again for the T409 stainless steel model.
