As soon as I buy a house, I'm getting a welder and making my own damn stock lookalike long tubes. fek the police
I am starting to see benefits to going this route. If Extrude Hone isnt try to blow sunshine up my exit pipe, there wont be much of a loss in power. The pluses: cops wont have a leg to stand on if I do get pulled over (neither will the smog jockies), I can run in lower classes at autocrosses (headers automatically bump me into a higher class), and if the LT1 exhaust fits well, I can raise my cross frame up so it isnt so low.
We'll see. I still think Extrude Hone's boast is a bit inflated or the test conditions were "extremely favorable".
I know exactly how you feel. I have some EM long-tube headers sitting in my garage, and I fear putting them on because of the smog-****'s out here. I have JBA (CARB leagal) short-tube headers installed, but I want more power. I may sell these LT's and just have my heads ported...at least that will pass smog.
Centralcoaster, I dont know about you but the CHP are pulling that vehicle inspection crap up here. And CHP love to hang out on the highways around my area. Not worth the fraking fines and impound fees involved
Yikes! I have not heard of that happening! I thought they were focussed on speeders and drunks. Random pull-overs for checking for illegal exhaust systems and other smog violations has to be an ungodly expensive/low return program. I plan on the "one-day-every-other-year" program and take my chances.
The comment about the smog checkers not familiar with stock systems on C4's is correct (at least in my area). I discussed this with a smog station guy about a year ago and his comment was just that. It is only when they see something obviously after-market that they go to their computer to see whether the part has an EO#.
