this weekend. Its been a long wait. I ordered them thru a local speed shop 3 weeks ago and had a tentative install date of that first Saturday. Friday rolled around and hadn't heard anything so I called and found out ARH had never shipped them but would ship them the following Monday, so rescheduled install for the next Saturday. The next Thursday came and I hadn't heard anything, so I called and found out that again ARH had not shipped them but would get them out the next day. So, again I rescheduled for the following Saturday. Finally got the call last Thursday that they were actually here, so I got them installed this weekend. I didn't have the car dyno'd again, but I plan to sometime soon. I'm interested in seeing what the ARH headers and catted h-pipe gain me in hp and tq. I emailed a request to Brenspeed for new tunes now that I've upgraded the exhaust, but haven't heard anything yet. I can really feel a difference. I haven't been able to really get on it hard yet because it rained all day Saturday and was still wet for most of yesterday. I'm staying with the stock mufflers for now, but will probably swap them out for Magnaflows sometime this summer.
