Hey guys. I am building a 2000 si coupe for boost. almost done too...here is my issue though. I have an apexi ws exaust now......it is the same mm as the n1 except the muffler is different....think it worth selling it to buy an n1...or should i keep it for a while then eventually just get a thermal exaust? help me out guys! On pump im looking for like 300-325 whp....any higher then that exaust will not be ran on the car. Opinions please guys thanks!

 

just buy the thermal r&d 3". you wont be dissapointed.
