I'm very interested to see how this turns out. I spent the day hopping from performance shop to performance shop today. My plan for my 2nd GT take off muffler is an H pipe.
The first two shops wouldn't bother with the car, they havent touched an 05 yet. The last one would, but for a true dual setup w/H pipe, they want $1500 bucks. No way!
So we jack my baby up at the first shop, and a mechanic comes over after the salesman takes care of another customer. He says, this isn't that difficult, he said I should replace my CATs with Cobra ones, and purchase a H pipe and from ebay and to take it to another shop. He said he used to do a lot of mustang work, but now works at this shop doing strictly vanilla jobs for non-performance cars.
So heres my question, the dude gets under my car....looks at the CATs and says, those got to go. They are robbing you something in the neighborhood of 50Hp. I'm wary of mechanics these days, but what do you guys think.
Also, any suggestions on how to get this done. I'm in the DC metro area and I'm having a rough time finding a shop that will do it and not rip me off.
Perhaps after Afixer finishes his setup, I can get an idea of how to better go about this.
Later.
