Re: just got the obx cat back ...
You'll love the sound. i installed it on my car. Fitment was quite good. Just get better clamps than what they sent you. This kit was complete with the slant tips as the only option when I checked. What sold my on this system was a sound clip on you tube of an c5 corvette. I know it wasn't apples to apples, but seriously.

Re: just got the obx cat back ...
update :
i've got it on abot 75 % enough i started it to get an idea of how it's gonna sound . in my opinion it has a deep magnaflo sound only louder . i got sum supports an clamps to finish instaling an yes the clamps suck so i'm gonna either buy all new ones or weld the joints not sure yet . i like it better than the 2.25 " flowmster 40 i had on it . i'll get a sound clip up this weekend i'm gonna put a posi rear end in on sunday hopefully .

Re: just got the obx cat back ...
I cant help but wonder if those are true crossflow mufflers... I have my doubts. Sounds good, though.

Re: just got the obx cat back ...
i can't wait to get some miles on it so it deepens up a bit more . i'm happy with tho . to be honest it's a little quieter than i wanted but considering i'm running headers an no cat thats prolly a good thing . don't need johnny law pulling me over all the time .lol

Re: just got the obx cat back ...
The fitment looks great! the length of the tips sticking out is nice
And once the muffler breaks in i bet it will be louder
