Picked it up from the exhaust shop today and drove it to my storage unit where it will sit until it is warm... Exhaust sounds good...it is quiet a bit louder than my e30 m42. I am running 2.25" pipe through two magnaflow mufflers.
Also right now I have a large hole in the firewall that the motronic cable is going through so I am getting a lot of engine noise and wind. I stuffed a shirt in there and it helped a lot.
First reactions are I really like it. I didn't really have a chance to really get on it. As it was the first time driving it, it is 20 degrees outside and there is snow on the roads.
No smoke or odd sounds from the engine, has around 160k on it.
I cannot wait until it warms up and the roads get cleared off to really test it out.
It took a month from the time I started until I was running and driving.
