Thanks for suggesting using a cat, I didnt think about the smell issue.   I will most likely go with the perf. cat.   I see one on ebay that would work perfect.   I saw a much cheaper one thats 2.5" inlet/outlet and I wonder if that would work well with 2" exhaust, Im not an exhaust expert.

Silver is running a Calmini header, catless into stock size tubing and muffler. The exhaust smell is nasty without the cat and I wouldn't recomend going catless on a ragtop. It seems to work fine, though.

    I run a softop with no cat and have never noticed exhaust smell.  My husband's Samurai also doesn't have a cat and no exhaust from it either.  He did have trouble with exhaust smell when he tried to rerout his tailpipe, but not since its back to stock location. 
     I run no cat, turbo muffler and 2" exhaust on my 8valve Sidekick.  I like the deeper sound, but didn't really notice the change increased power.  I need a header though.  Thats one of the two mods I have left on my wish list!  (but its an everevolving list!)

Well, I guess the extra holes in my body and the tailpipe getting pushed/bent forward is probably the cause of the exhaust leeching into the interior, but I still suggest using a cat, even a performance one as it does help the smell and the environment...
Had a cool sig pic till I changed the text... sigh...

To best avoid smell and CO, exit the exhaust to the side and not out the back.

Here in california, we have the most nazi smog regulations, so I cant get rid of the cat. I wish mine was the 49 state one, so I could put all the 49 state accessories, like the calmini header and the intake and cam. I can still put a header on it, but it has to be the DT 50 state one, and since the cam doesnt affect smog too much on these, I could put one in it.
Runnin' it stock with 225/75R15s and an unmodified 8valve TBI motor (I need a doug thoroley header and a cam) (more power) (1.6 liters of madness) (vroom + sewing machine sounds)

Ok well i have stock exhaust, with a high flow turbo muffler, i have a custom 3.5" short ram intake, "yeah its a little ricy sounding"   and you here the intake more then the exhaust, "yeah it makes a funny sound when its ideling"   and on a dry day i can spin the back tires through first, chirp into seccond, on a wet day you are lucky to keep traction until you hit third, and if i want to i can spinn then through 3rd on a wet day, it is an 8valve motor, proted and polished when i rebuilt the head and timeing is a bit advanced.
All things must start and end, the key is to not let them start and end in the same place.

The Green Goblin is running a Hawk header into a 2" high flow cat, 2" Dynomax muffler and 2" tailpipe. The sound is very quiet idling, just as quiet as stock, but a little deeper tone and when I get on it, it gets a little louder than stock, but also deeper tone. Kinda sounds like a good throaty performance ricer sound, not the buzzy fart can style ricer wannabes...




That sounds like something Id want to look into.
The only thing is that Id want to turn it into dual 2"s
Header ---> 2" CAT ---> 2" Muffler ---> Dual 2"s with tips.


Do you think that would ruin performance?
Can I run bigger duals?  2.5"?
What about all that "backpressure" stuff?
What do you think would be the best setup?

Inquiring minds want to know!!!

I dont have a Sidekick at this time, but should have a machine soon. I plan on purchasing a stock unit and adding aftermarket things that I want. This is a common thing to do with Suzuki's these days, especially with Calmini backing them up. Anyway I plan on getting a Calmini header exhaust combo [ NO CAT ] and routing the catback through their single tube rear bumber [ Calmini of course ]. I figure this is one of the best set-ups available and is designed for off-road driving. I am not a fan of the stock Sidekick rear bumper because of how the exhuast tail-pipe runs through it, causing it to melt and things. It just doesnt look good! I guess buy installing the Calmini unit this problem would be eliminated. I also have no air-care or smog regulations where I live here in British Columbia so chopping the cat is no problem. The 1.6L 8V sounds great with a performance exhaust system, well I think so. Maby someone could post pics how they have their tail pipe routed. :-\
