Thanks for the reply and congrats again. Is this the muffler you're using? I just don't want it to sound like those old glass pack mufflers.

Thanks, actually mine is the 12278 which is an oval body, so I'm assuming the round case is louder. I used to be a fan of flowmasters until I ran this setup and I love it especially dumped.

Yeah I am currently running the magnaflow 2.5'' dual in dual out but thought I would try something new. I should probably stick with what I have huh.

Lol yep I have a 1/5 ton chevy work van its so nice and quiet I like drivin it but then the truckn is so much fun to drive but I better keep it as quiet as posible. There is a place up the road from me that does all mandrel bends in stainless tubeing. No more leaks thats what I hate about headers there so noisy I guess im just gettin old.

i have a big case magnaflow, and i love the sound when i am going down the road, and at WOT... but i cant ever hear my cam with these magnaflows.. i could through the flowmasters, but i ordered a cutout to solve that problem!

should be able to hear it with it opened up.
