opinion on exhaust buy.

[My03infiniti]

Im currently in the market for an exhaust for my G35 and thought I was set on the greddy spectrum elite exhaust, and then i found a guy on craigslist with a magna flow exhaust for sale. It came off his Z and it sounded pretty good. I just wanted some opinions from some people that have bought either one of these before and may have some advice for me. I have extensivley researched the two and they sound almost the same from the sound clips I've heard, but the magnaflow retails for 1k vs the greddy at 800. the magnaflow is also used but its a swinging deal (i think).

does anyone have any advice for me. Any advice at all is appreciated.

When I get my g35 coupe, I will only get the following:
Motordyne Exhausts
HKS Hi power Exhaust
ARK exhaust

All the videos i've heard with these installed sounds very aggressive with a deep growl. I've gone with cheaper setups before I got my ARK on my g37 and I regretted right away since you will be hearing that exhaust note every second you're in the car.

I'd suggest NOT to buy a exhaust that was made for the Z, you're going to have to find extensions, extra welding, and the tips aren't going to line up like it should and etc. You're just going to end up with a huge headache, especially if the welds weren't done properly and you end up with exhaust leaks. bleh
