Hey guys so this is my review on the FI Resonated test pipes with topspeed axle back. I was really hesitant at first with doing this setup because I couldn't find any videos on it so no idea on how it would sound. Pulled the trigger on it in September, and waited the 4 weeks. No check engine light after installing the test pipes. Drove around for a one week with the topspeed axle backs and I liked it a lot, but picked an Invidia catback to pair up with the FI's. It sounded great, and there was amazing gains but I liked the topspeed better. So I actually ended up actually taking the catback off, and going back to just the FI RTP + topspeed axleback. . It sounds just like the topspeed axle back but the sound is louder. It is pretty loud but not too annoying to bother you. If anyone has AAM short tails, it sounds pretty much similar to that in volume with stock cats. Surprisingly no drone at all. 6th gear is dead silent, the exhaust doesn't make any noise unless you put your foot down. It gets loud after 3500-4500 rpms but it stays that same volume all the way to redline,it doesn't get any louder after that. There is a very light hiss at low rpms, but there was actually more hiss with the invidia catback. Anyway, I'll attach some pictures below of the install, and a video I took with the gopro the week it was installed. It does shoot flames if anyone is curious hehe. Video link of flames will be there as well.




Thank you Next Level Performance for helping me order them. The FI team did a great job on the build quality, and packaging was amazing.
