Well its time to lose the cats that are on the car while its up in the air.

How does the car do with any rasp? If you have any at what rpms? cruising? accelleration?

Anyone have sound clips? Ive got a borla also.

Overall, would you recommend it over 2 bullet mufflers in place of cats? the pipe is much cheaper, but if it sounds like **** then i dont want it

opinions please!

I have flps and run no cats, threw the exhaust(hooker) it sounds really nice, deep and throaty. When you open the cutout it sounds mean as hell, but may be to loud for most.

I have long tubes with borla exhaust, no cats. Its loud. I have 1/4inch open plate for the right exhaust which completely bypasses the muffler (look at borla design if not familar). Low rpms sound raspy and annoying in my opinion.. But wide open throttle sounds sooooooooooo good. Really sounds bad *** at wot. Mine sounds kinda crappy down low cuz some of the exhaust isnt going through a muffler.

My friend has long tubes no cats, hooker cat back exhaust.
Quieter than mine as it should be, sounds fine.

Kmook, has long tubes going to an x pipe with i believe dyno max bullet mufflers, sounds incredibly bad *** at wide open throttle. not sure about down low.

that would be sweet if you could get a vid of all rpms!


Anymore opinions? especially on cruising speeds, 70mph in 6th gear, etc.

The cats will quiet it down a lot. Try to incorporate them if it is a street car.
