n1 + uel will be super super loud bro. i have the invidia r400 and tomei uel and its pretty loud everytime i drive. i can drive quiet but i have to accelerate slow or else itll be loud and rumbly. i actually bought the tomei uel headers from a guy on facebook. he was selling his n1 and tomei uel headers and he said with that two set up alone was waaaay too loud. n1 is already loud alone, an if u get a front pipe then its over. lol i recommend switching to invidia r400. its loud but not crazy loud like n1. and it doesnt drone as much
