Just was checking out how well my new camera would take in car vids without a mount. I was going to get on it up the on-ramp but a cop pulled up across the intersection before the light turned green. Just after getting on the 2nd freeway I hit about 125. If you hear some metal rattling, I had the back seat down so you could hear the exhaust better and I had my golf clubs in there.
Chambered mufflers are going to sound different from straight through. I think it sounds more old school. I get a little trumpeting right around 2600 RPM, just for a brief second. The only drone I get is with the A/C on and it happens at idle and about 1300 RPM. Again, this is only with the A/C on. Wierd huh?
I have been running flowmaster AT s for almost two years and I get nothing but complements. They sound better after they break in (1000 miles or so.)and even better with a CAI. :yes But they do sound like crap with an off road x-pipe. High flow catted x-pipe sounds great. Dont know guys hate flowmasters so much on this board.
ok so I have touched on this subject awhile back in another thread so i'm going to copy it and post it for you. But your best bet is to shop around first and compare each exhaust to the X or H pipe you want (compare on youtube). Do not settle with cheap, you will regret it. You like the sound but it's more $$$...save and buy it or you will be wondering why you did not just save your money and get the better part.
ok here is my old thread post
yeah O/R basically means no cats...H pipe creates more turbulance between your left and right exhaust giving it a bit smotter sound..(had this on my 90 5.0). With that said you have the x pipe which gives you a raspy type sound higher pitched then the H. Every person is different in what sound they like so the best thing for you to do is....youtube it....some videos have good quality sound. Now keep in mind the sound of your X or H pipe will differ with you mufflers(research this to on youtube). I found that I enjoyed the sound of Borla with the X pipe vs Flowmaster, Etc...Lastly keep in mind headers, this creates another unique sound for your exhaust. bottom line it's good to get the research (people here, youtube, carshow) and then get a plan for your set up.
Hope that helps you a bit.
Key note unless you have a high jack with high stands installing the cat back pipe is near impossible. You can manage by jacking it high and taking you rear tires off.
