Re: Exhaust Help
Also, I wouldn't recommend any mid pipe without cats. The best sounding sixer is a quiet sixer. A more mellow tone is your best bet. Once you get around 2500-3000 rpms, it tends to get higher pitched.
As far as back pressure, you might lose a small bit, and I mean a small bit of torque when you upgrade your exhaust, but its not too noticeable. I think the stock exhaust is 2.25in, and some aftermarket catbacks are 2.5in. The slightly larger diameter reduces some backpressure throughout. You will gain that back with some other small bolt on mods, and a good tune that will maximize the effectiveness of the exhaust.
If you do a custom fabricated exhaust get 2.25 piping throughout and you'll have no problem as far as losing backpressure.
As far as price, converter back systems that retain the y-pipe are the cheaper "systems", they just bolt right up to the stock y-pipe, but again, this isn't a true dual system.
I've heard a custom fab exhaust can be the cheapest route, get 2.25 piping and the mufflers of your choice. Plus this way you get true duals.
