Honestly, I've been down this road with my Crossfire and it was kinda frustrating. For your situation, I would suggest looking at the Magnaflow Street Series Cat-Back Performance Exhaust System 16633 because it fits the budget way better than the Borla. I tried a custom resonator delete first cuz it was cheap, but unfortunately, it sounded like a raspy mess and the highway drone was LITERALLY unbearable... definitely don't recommend that route unless you want a headache.

The Borla S-Type Cat-Back Exhaust System 140111 is nice but usually goes over that $1k mark these days, which is a bummer. If you're worried about cabin noise, definitely have a pro shop check the fitment. I had issues with mine vibrating against the heat shield at first. Plus, the Magnaflow gives a decent little bump in throttle response, tho you wont feel a massive HP gain without a tune. Good luck with the build tho!

Just sharing my experience: so I went through this exact same dilemma with my 2005 Limited about two years ago. I'm a bit of a data nerd when it comes to backpressure and flow rates, so I spent way too much time looking at the technical specs of the available systems. I actually ended up going with a setup that's a bit different than the usual recommendations mentioned above.

Basically, I was looking for something with a higher quality stainless steel grade (T-304) and ended up installing the Remus Sport Exhaust System for Chrysler Crossfire 026004 0504 and honestly, it's been fantastic. Here is the technical breakdown of how it worked out for me:

1. Low-end torque: Unlike some custom resonator deletes that can actually hurt your low-end pull due to loss of scavenging, this setup kept the backpressure right in the sweet spot. I noticed a slight but measurable bump in the mid-range.
2. Sound profile: It stays very deep. It has this tuned, European growl rather than a raspy American muscle sound.
3. Drone: This was the dealbreaker for me. At 70mph, it's barely louder than stock inside the cabin, which makes it perfect for long trips.
4. Fitment: It bolted right up to the factory hangers without any weird bending or hacking.

I also looked into the Supersprint Rear Exhaust for Chrysler Crossfire 845306 which is another high-end option if you can find one in stock, but it was a bit pricier. I think sticking to a tuned muffler system is way better than just hacking out the resonator if you want to avoid that cheap, raspy sound. Good luck with the build tho, these cars are sooo much more fun when you can actually hear the engine! 👍

Seconding the recommendation above! Honestly, I've been there with the resonator delete and it was a mistake—the vibrations actually felt unsafe for the interior trim long-term. My current setup is a full stainless system I got last year and the backpressure is way better for engine health. It’s basically a balance between flow and backpressure; if you go too wide, you lose low-end torque. Just stick with a reputable brand like the ones mentioned for a *safe* daily driver! 👍

Seconding the recommendation above! Honestly, you can't go wrong with a high-quality stainless steel setup from a brand like Borla or Magnaflow if you want that daily-driver balance. Just be careful with custom resonator deletes—I've seen so many people regret the drone on the highway!! I'd suggest sticking with a reputable cat-back system and maybe getting a pro to install it to ensure the fitment is perfect. Better safe than sorry when it comes to cabin noise tho.
