Would the hight flow cats cause any drone, or make the exhuast too loud? Right now my exhaust is quiet in low RPMs but when I hit the gas it growls nicely, especially above 4k rmp. Also, would the hi flow cats cause me to fail any emmissions test? Thanks.

03 Doggy door 5at with 103k
Just goin top to bottom; AEM CAI,5/8'' spacer, stainless headers, custom 2 1/4'' true dual exhaust, underdrive crank pulley, throttle body coolant mod, full revised Z suspension, 18'' stock Z rims, stillen adjustable sways, basic ground wire kit, drilled + slotted rotors, hawk pads, painted calipers and a few other cosmetic things. I had my mind set on getting the uprev osiris tune but can't because the car was built in 8/02. Also I have been looking into swapping my rear diff for one from an MT with the vlsd and 3.5 final drive. Just wondering if I can really do anything else other than a turbo/supercharger. Thanks.

I was thinking about doing that and the only thing stopping me is the money. I'm a 19 year old college student and from what I have seen on this site it looks like a could get the 3.5 shipped for around $350-400 and installed for another $200 but anything bigger looks more around the $750-1K range and i'm not sure but would i need an aftermarket LSD to go with a 3.7 or a 3.9. so basically what i am asking is do you think the 3.7 or 3.9 would be significantly quicker than the 3.5 and worth the extra money required to make it all work.

I went from a oem 3.5 down to 3.3 to help with traction and save me from having to shift into 5th in the 1/4 mile. I found a ~700rpm drop in 6th gear at 70mph. Given the power of my car before and after the mod I can't say how much the mild change from 3.3 to 3.5 would provide but IMO you are better off just waiting and doing it right the first time.
*Again this is if you don't plan to boost your car down the line. If you do, go with the 3.5 or even keep the 3.3*
