    Are true duals better than catbacks?

    I've been weighing my options for a new exhaust system lately and I've come up with another question. Would getting a true dual exhaust system custom made for my car by a local shop here be better than buying a catback and off-road y pipe system off of the internet?

    from what the research will say, yes they are better. especially a custom built system

    Ok. Well does it matter what kind of shop does it? The guys I'm talking to do a lot of custom exhaust work but they do all around maintenance stuff on any car. THey did the custom exhaust on my friends foxbody 4cyl Mustang, his 2001 Dodge Stratus R/T, and my dads '79 Trans Am 455 H.O. Would they be a good shop to go to?

    If you don't mind the smell of gas and the car being loud almost all the time then yes a true dual system would be better. It all depends on muffler choice really how loud it is. If you really want to go big get true duals over the axle, its not cheap though. After its all said and done it's not gonna matter as much unless your making big HP numbers.

    If I remember correctly, the shop quoted my dad around $280 to do it on his '79 which sounds amazing. As for the sound, I want the car to be loud. It is not going be daily driven so the droning on the highway wont be an issue. And when I get the exhaust done, the car wont have much HP over stock, but I will be upgrading things over time and would like to have the basics already in place for when the time and money comes for the big mods.

    Sounds like you could go either way. A true dual setup with flowmaster single chambers is loud but sounds really good. Either that or bullets.

    Think flow would be around the same, very minimal difference. I think true duals and sweet thunders sounds real good as well as flowmaster 10s.

    I always had myself planned on getting true duals with magnaflow 4x9s (tame down low, screams up top) but ended up with a GMMG. Funny how things turn out.

    No problem, true duals are the only time flowmaster belong on an Fbody.

    To the OP-

    Here's a clip I particularly like... spiral flows with an x pipe.

    This thing just sounds NASTY! I'm sure the thumping of the cam also helps to give it some... "character"
