I recently put in a catback system. It was a custom one done by a respected exhaust guy in town. He took the second cat out but left the one with the sensor in. Its louder but I want more.
Would an aftermarket cat be the way to go? If so, any recomendations.
Yes the high flow cats make a big difference. I'm running a high flow in place of the stock cats and single in dual out original 40 flowmaster, and it sounds pretty good. I'm debating right now on whether or not to switch over to a true dual setup using a X-OVER pipe. It sounds good now, but I want it to be as loud as possible, and i'd like to keep the thing legal.
What type/brand muffler are you running on the catback? Are you running headers? Does your state have visual inspections of the exhaust.....you could just run it with no cat.
What I am thinking about is getting a good set of JBA or Bassani equal length headers and a Bassani or Flowmaster mandrel bent Y-pipe......going through my Catco cat and Flomaster 40. The only thing stopping me is I dont want to have issues changing spark plugs, or leaky exhaust gasket(s). I have to do more research.
Phil, if you want loud, take a look at the Moroso SpiralFlow mufflers. They tone down the harshness, but not the sound level. They're very good performance mufflers. I have one on my Bronco, in series with a single chamber IMCO, and even with two mufflers it's still loud.....
I know this has been discussed before, but is there any reason why true dual exhuast would be louder than split dual exhaust?
i believe it would be because each bank is on their own separete side and all the exhaust isnt just going out one pipe so theres more time inbetween each cylinder
IF you want it loud and poping, then put duals with 2" or 2.25" pipeing and glass pack mufflers( the smaller the better).
For all practical means, either get a high flow cat or just gut your existing cat and put on a small muffler like a 12" or smaller glass pack or cherry bomb or even the Moroso SpiralFlow mufflers like thelonerangerxlt suggested.
I really prefer the sound of flows over glasspacks, would i be able to get it louder with true duals? Right now i have completly stock exhaust except for 1 high flow cat and single in dual out original 40 flowmaster muffler. What i'm thinking is Bassani equal lenght headers, X-pipe, high flow cat on each side, original 40 on each side, 3 in pipe all the way. What do you think?
if you want perfornance the last thing you want is glasspacks. the design actually causes more backpressure robbing power and fuel economy stick with a good set of turbos
So you think with 2.5" pipe it would work pretty well MBBFORD? I ain't got the money to run out and buy it all at once, but I can start rounding up the parts and eventually i'll have everything i need. I don't want to put anymore money into the split dual exhaust and be dissapointed and then switch to true duals anyway.

Glasspacks is pasically a 3 1/2 peice of pipe with directional baffles.
If you turn them the oposite way they should be ran, then it is just enough to take out the harsh sounds of straight pipes. GO and run a bigg 32" replacement turbo muffler and compare the two and then tell me which one flows better.
masseysbronco, for true dual exhaust comeing from the headers or exhaust manifolds it would be better to run 2.5" pipe or even 2.25" because of the abillity to flow all that exhaust seperatally.
Now if you have 2.5" pipe running into a dual inlet muffler then you would want the 3" single outlet for the 2 combind exhaust pipes to flow freely instead of a continuing of the 2.5" pipe which would cause backpressure resulting in a loss of power.
(catback)Basically 2 small going into 1 big is ok.
(duals)Or 2 medium sized pipes flowing all the way back with possibly a H or X pipe in there also will perfom just as good if not better than the catback and WILL be louder.
