X Pipe or Straight with resonator delete on E550




I spoke with a few people locally mixed reviews they say the straight pipe gives more noise but the X pipe is better airflow and increase HP......! I'm looking for a more aggressive sound in the low RPMs but not too loud when I'm cursing.......also plan to change out the tips to give it that E63 look......!
