Exhaust Challenge
Tax season's coming around the corner and I'm expecting somewhere around $650 to be able to put towards a new exhaust system. I've looked around and still can't decide what to buy. I want the meanest sound possible while avoiding the crackling that plagues some exhausts. Let's see who can find the meanest setup w/out changing headers and having a sound clip as an example. I'm sure this will help more people than myself seeing as how many topics there are.

RE: Exhaust Challenge
long tubes with a custom 3" X pipe and Pypes 3"minicats welded in going back through a 3" dual setupwith 3" Force proseries mufflers and 3" tails.
it will give you a brutal sound without any popping and crackeling and be deep at idle
that's what i am going to as soon as i get enough money to fix my freakin car!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
damn thing has been down for 2 full years now. fvckin wife won't quit spending my money

since a centrifugal doesn't make any boost til up high, it will cause a lag

were talkin sound not power. and they wont kill it if u have a 11psi procharger lol

there is no lag. and for those of you that think 3" is detremental please get a clue. and do not use the term "backpressure" because there is no such word.
torque and hp production move up 300-500rpms but the peak will be higher. you won't lose power. if you do it will be no more than 5 hp and torque but that's highly unlikely. larger exhaust like 3" will give more of an arc in the torque curve compared to stock or dual 2.25 or dual 2.5". which is the main reason people think they lost power. they really didn't they gained more on top and the bottom remained the same which gives a wider range of power. not alot but enough to fool you into thinking you lost bottom end.
i challenge anybody here to post a dyno of a dual 2.25" compared to a dual 2.5"compared to a dual 3" on a V6 to prove you lose power. it's an urban legend. i have been around dyno's alot and have never witnessed power loss so great on the bottom end to make the larger exhaust not worth it. if you feel you lost bottom end then get steeper gears to compensate
a guy at 3.8mustang has dual 3" with an X and random technology cats and he gained quite a bit of power. more that you would expect i think 12rwhp and 14 ftlbs if i am not mistaken.
again please don't say you'll lose backpressure and teh bottum end will be teh suck.
if an engine is working to get rid of it's own exhaust then it's power production is limited. open it up and it can breath and spin freely without working against it's own exhaust or what some knuckleheads call backpressure.
you lose alittle exhaust velocity with a dual 3' setup but it's is really no worse than a dual 2.5" which is not worse than a dual 2.25"

again you have no idea. my procharger on a stock singleport made more power at 2600-2800rpms (around 150) at the wheels than a stock singleport at 5,000 which is about peak. so how much power did you lose with your supposed 3" MAC system
