im not sure what i want to do for my exhaust, i have it narrowed down to a magnapack or a borla pro xs. true dual is on debate with SI/DO

otto457

Dual SI/SO mufflers with an X pipe towards the front will sound the best. SI/DO or DI/DO will still sound good and will be a little less expensive. I still suggest an X pipe for DI/DO applications even if it has an internal X. SI/DO a better Y pipe up front will help. Really can't go wrong with either of your muffler choices. Borla may have a little less drone for the volume.

how far front would u suggest? i would think between the cats and mufflers, i figure thats just a given. but i want a deep rumble with low crackle and pop

otto457

If you're going duals put the X where the stock Y is now.

what do you think about high flow cats

otto457

Since you have an 06 you should only have two cats to begin with. Unless you want to change the sound a little, there's no real advantage in high flows.

im not sure, i like the sound of both but i cant find that perfect sound. and i do have two cats, it might sound a little out there. but wat about no cats but have a muffler(s)?

Need some info on muffler and pipe sizes,I think I got hosed at Midas. Should have known better. New muffler looks much smaller than original, and pipes also are smaller. Help, I'm sure this is restricting air flow ????
