But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

Amazing product! The original hp is back with better peddle response and a noticeable increase in hp/torgue from mid range to redline! The only reason for not giving all 5 stars in every category is after spending over $500 on this product magnaflow does not include all the necessary hardware. I had to buy new nuts, bolts and washers to connect downstream of the cat since the factory bolts are welded in place they obviously stay with the old removed component! Really Magnaflow???????????????????
