I just finished installing the Hotshot Header and ES Motor Mounts on my '04 Spec-v. I must say, I'm fairly impressed with both. I do have a question regarding the header though. I expected to have an increase in noise, but i fear that my car is going to start sounding like ur typical honda riceburner. The sound is raspy at high revs so is that typical? Almost positive there are no leaks. I've torqued before and after normal engine operating temp but i still feal like i might be having a leak. Basicly I just want to know if anyone else out there w/ this header has the same sound.
