Highflow Cats
Hey guys, this is always a fun topic. I own a '96 328is and I recenlty replaced both cats w/ Dynomax, high-flow racing pieces. The total cost w/ labor was around $550. The BMW shop wanted $900 to repalce 1 cat w/ oem.....lol I have noticed a louder deeper, tone w/ these cats

, BUT.... I have had a check engine light since day 4, now over a year. ECU still throws a Cat code at the techs

I hope this isn't hendering the performance or reliability of my bimmer. Hope this helps, also any feedback would be great, thanks
