Product Description


Not all performance exhaust systems are created equal. Borla exhaust products are made of 100% pure Aircraft-Quality T-304 Stainless Steel-inside and out. T-304 grade stainless is austenitic (non-magnetic) and has a high cromium content, which makes it nearly ten times more durable than mild steel and has over three times the life of T-409 stainless steel (an inferior grade of alloy used by some manufacturers). T-304's high tensile strength resists cracking and enables Borla to use thinner wall tubing for lighter weight.

Note: This system does NOT fit models with the 2.4L or 2.2L engine.


  • 1999-2005 Pontiac Grand Am GT

Exhaust tip note: Borla has changed the design of the tips that come with this system to a dual, rolled design rather than the one shown in the photo. There is a photo above showing the new tip style.

Reviewer: Tanner (, MO)
I absolutely love the sound and rumble that this exhaust give my GAGT, regardless of it not being bigger diameter then stock it still has mandrel bends which provides better flow. If you're looking for a not necessarily loud but not necessarily quiet exhaust that gives your car a nice and awesome sound then this Borla Cat-back is right for you. I LOVE this exhaust!

Reviewer: Steven S (Tipp City, OH)
I bought my Borla exhaust about six months after buying my 01GAGT new. Quickly decided on the look and reputation of Borla, and ordered it from here and had it installed in March of 2002. I can tell you that 5+ years later, the kit is still awesome and hasn't degraded a bit. The metalwork still looks outstanding, the tips only need slight cleaning from time to time, and the sound has been unwavering and delicious. From the first time I fired the car up after install, to starting it up after installing my Cold Air kit, the sound has been wonderful. It's deeper, with more rumble, and it screams when you get on it. It's truly a great system, and I've been running it for years now with zero problems. I've modified my car in many ways, but to this day, I still say this kit was my favorite, and money well spent.

This exhaust system is way better than the stock system that came with my 04 Grand Am GT. It sounds way tougher at about 2,200 RPM, and produces a noticable increase in power. Not only that, but getting it from PFYC is also a great way to save >$100. Overall, I'm way satisfied with it. It may seem a little expensive for people who don't race too often, but I think it's worth it, even for the street.

Reviewer: Stephen G (Portage, IN)
When I first received the package containing my Borla exhaust system, all the parts looked astonishing shiny with it's stainless steel coating. It is more of the exhaust system you should buy as a more cosmetically minded customizer of a Grand Am. It changes the exhaust note slightly, only when letting off the accelerator it induces a little growl of back pressure. To truly escalate this sound and the overall exhaust loudness, try taking it to a shop and have the resonator by the catalytic converter cut off and replaced with straight pipe. It even then will not be extremely loud because of the muffler on the other end, but it will make this much more worth an $800 buy.
