^^^ thats true, plus ive been to many shops that do exhuast and never had an issue with them installing LT's or deleting cats because its illegal. The only trouble you ever run into is money on installing LT's because there a PITA to do or the mechanic just doesnt want to bother with it because he will be spending most of his time on your car through out the day, which has been my experience with some mechanics. LOL, one mechanic took 2 days to install LT's on my prior Z28. It helps big time to take it to someone that knows what he is doing and has done it several times, that way you save yourself alot of time and headache.
