interesting....that sounds awesome! I actually already have the longtubes..... I bought them off of a friend about 6 months ago and they have just been sittin in my garage. I got the ceramic coated LT's & ceramic coated Dr. Gas x pipe for $300. Was that a good price? and since I have them do you still think that it would be a waste to have them installed?...price for the install is $375 at my local speed shop. but i think they would guarantee my hitting the 400whp mark?
