This is definitely one of my favorite mods - combined with Fister II's it sounds like a freight train when you get on the gas. On track days, people often tell me its their favorite sounding car at the track. Comments like, "I almost don't mind getting passed by you, because your car sounds so good." The weight savings is significant, and in the right place (Fister I's will add some weight back, Fister II's are lighter and increase wight savings). It feels a bit faster on my butt dyno, and once I install Nam's cat delete pipes it can only get better.
I have the Cargraphic true X-pipe with Fister Stage III’s and to say it’s ferocious isn’t enough it’s off the charts loud lol...but actually manageable (barely) at light throttle but get on it and the bark is absurd lol. My original cat felt and sounded bunged up now my car runs cooler and feels like it’s breathing easier obviously but only a fresh dyno run will tell whether it’s making any more power or torque my butt cannot. I do wonder if Stage 2’s besides less obnoxious might also put a little needed back pressure back on vs the basically straight through design of the Stage III’s?

Glad you like, Jim.
My X-pipe with cat delete going into Fister 2s makes the most insane sounds. Combine great sound and huge weight reduction, it’s a win win IMO. It’s a treat to the ears when I drive, and a fantastic view when I wrench

Yep, the Fister III's with sport cats were so loud that the shop that did the install actually complained it was too loud. As they started up the car, a car alarm went off in the parking lot across the street. I don't think they had the clamps line up quite right, and that made them even louder. Here are a few sound clips comparing Fister I's II's and II's with sport cats. I've swapped mufflers out so many times now I can do it blindfolded. Like the three bears, the middle one was just right for the sportcats.
Sorry, for disappearing guys, I got a little busy yesterday.
I have attached the before and after dyno run for everyone to view. We have tested multiple different set-ups and cars for the x-pipe and this x-pipe was the one that performed the best. I know there are other dyno's out there that differ in results. Each dyno is going to get different results based off of multiple different factors and vehicles.
I can tell everyone that if you have not done the x-pipe on your 993 it is definitely something that you should look into adding to your vehicle. As most of the owners have said on here not only does it add performance it also adds a thrill to the exhaust note.
