@@physicalstatus3009 isr test pipes were $350 brand new, then the wicked muffler/resonator installed was $100 other than that it had muffler delete with dual tips. But honestly it was way better when I got the isr exhaust it felt faster and sounded more better
With this set up I had ISR Y pipe and resonated isr test pipes with wicked flow resonator and muffler delete also the piping was 2.75 inch it would make lots of pops, but it kinda was loud in the inside when driving the car fast lol
