Ok, a straight pipe without cats and no resonators sounds good in start up and below 2k. After that it gets way too loud and it's not tasteful. Sounds very tin can like and just not desirable. Keep the cats if you are going to use your stock manifolds or shorties. LT headers sound descent without cats. It's gonna be loud and raspy with that setup.
Any Speed over 55 mph may kill you... that's why i drive 60
