Thursday evening I went to my buds exhaust shop and we cut out the mid-resonater and welded in a "s" bent pipe in it's place. WOW I'm tellin ya's, if you want to consider tearing out the air restrictor step1, then this should be step2!! Made a very noticeable difference in the entire attitude of the car. The tone is a deep 'growly snarl' a bit noisy up to 2000 rpm perhaps. Top end acceleration and throttle response is amazing (at least on my car). Quite noticeable increase in power!!
Spend the money! go do it! You won't be disappointed!
The only thing that sucks is you can hear all the sound coming from the left rear of the car when you're driving, gonna have to go duals soon..... ;)

wtf...isn't the "mid-resonator" (the big thing before the muffler in the frame well) the cataylitic (sp?) converter? I'm assuming you ganked the muffler (stretches horizontally across the bottom of the car before the gas tank) from the system, right??

yup that's the one! It seems to be the biggest cause of comfusion in the LH cars. The guys at the exhaust shop called it a resonator, but it does perform a mufflers' job. The car sounds the same, only louder and more aggressive. I didn't lose any low end power that I can tell, she was always a ballsy off the line car to begin with.

i've been considering this...i don't really want to straight pipe like you and wolf have, so i was wondering what would happen if you went cat back with a single pipe, split it, and then throw a high flow flowmaster or borla on each end? would that be just like straightpiping the stock exhaust but with 2 outlets? yes, that sounded weird...what i'm trying to say i guess, is it more desirable to replace the stock muffler with a dual-out muffler and then run pipes straight back or is it better to split the pipe and run a resonator off each end near the tip? would there be any performance difference? personally i like the look of having a resonator on each end but if the performance is weighted either way i'd go with that over looks any day.

thanks for all the help on the :exhaustive: subject

damn, i had to. i apologize, guys. thanks anyways.

Last time I checked, the catalytic converters are right on the engine block
at the front of the headers. So I don't
see how replacing or removing the resonators
or collectors or whatever they are called
would affect emissions since the catalytic
converters are right at the engine anyway.

Two cats hang off the exhaust manifolds, one on either side. The "y" where it all comes together is another cat actually. The best set up for the exhaust is of course dual exhaust, though I'd try to incorporate an 'H' pipe of some kind there. Cutting out the muffler gave a significant performance boost, and a sound like a Mustang with the flowmaster exhaust, so running twin pipes out the ass would open up even more ponies! That's gonna be the next step down the road.
