First off Tony's customer service is top notch as many others have stated.
I opted for the non-resonated SS muffler version. The install went very smooth, everything needed was included, the instructions were great too if you need them and everything fit and lined up perfectly. I constantly get compliments and questions about this exhaust. I am currently at stock ride height and do not have any trouble with this exhaust scraping.
And here is a quick video of the cat back.
Once I saw that Tony and his crew were making LTH's I knew I had to have them too so I placed my order. It took about 4-5 months to get them but, was worth every second of the wait. The quality of the materials and craftsmanship was very apparent. The install is really straight forward but between the "Demon Bolt" and the tight spaces it took some time.The install took me about 8.5 hours (again worth the work and wait). No CEL after 10k miles.
The sound of the catback was great but when I added these it took it to another level. The tone remained basically the same but was much more raw and throaty. Before the LTH's with just the catback I didn't hear any hiss but after the LTH's were installed the hiss is pretty loud at about 2000-2500rpm when you release the gas, it may not be for everyone but I love everything about this complete exhaust system including the hiss. This is the loudest combination that Fast Intentions has to offer, still tame at idle but, a beast when under load. Thanks for the great products Tony!
Heres a few quick vids with the LTH's and CBE
Here is my favorite video, its an in car shot from my father in laws C6 Corvette
I took the car to UpRev in Austin to have it tuned a few months after installing both the CBE and LTH's. We did a few pulls with the car just the way I brought it in which is the pink/purple line.
Then installed Stillen G3 intakes and did a few more pulls which is the blue line.
And finally the red line is after the tune.
So basically when I pulled the car on the Dyno it was at 301hp/246tq, then I installed the G3 intake and got 310hp/251tq, and then the final numbers after the tune and 17 pulls were 310hp/252tq and safe a/f ratios.
I hope this helps someone that's trying to decide on an which exhaust to get. You wont be disappointed with these products or the company they come from.
Thanks again Tony!!
