Great info. Now if we could all go to Indy to get it done it would be great. Sounds like you found the shining star in muffler shops. Last time I needed tailpipes installed they put the car on the lift, raised it up, looked underneath, lowered it down and politely asked me to leave. The one after that just looked under the back and laughed and told me NO! And that was just tailpipes! Like I said, I mess with the car ALOT so bolt-ins work best for me while I admit that weld-ins are a better option for most. Actually I don't think I've ever seen a pic of them welded in place. Can some one post a pic?
