what exhaust is the best to get for my 1989 mx6 gt 4ws or wher to go to get it done at what size or where to order it from

 

[Dyoel182]

Unless you can find a HKS set somewhere you're looking at a custom job either from someone here on the site or a local exhaust shop. As long as its 2.5" or larger you're good to go on the turbo setup because it really frees up the power. Call around to local shops and see how much they'll charge for a cat-back or full setup and what kind of bends they'll be using.

Since you have 4WS, the best size is going to be 2.5in. I have the HKS cat-back and it rubbed on the 4WS bar when I turn.

3in might be hard to get in there without problems.

what is the best preformance muffler

 

[88MX6GT]

I have a MagnaFlow, 3" in 3" out w/3" tip. I have one of JayB's exhausts. Expensive, but worth the money to me. You can always have a shop custom bend ya an exhaust like Dyoel182 said. Mine is 3" from turbo back, no cat. But as mx6gt91 mentioned, you have 4ws (I guess, I can't see your tag right now) which may be in the way if you get a 3" exhaust.
The MagnaFlow is polished and sounds great, and the 3" tip is great looking and not big and ricey, so I love it.

edit: check my yahoo page, it has a pic from the back of my car of the MagnaFlow muffler and tip. The address is: http://photos.yahoo.com/hybridmx6
and go to My MX6.

what is no cat is that good

 

[88MX6GT]

Hehe, no cat means I don't have a catalytic converter on my car. JayB offered his exhausts with ot w/out it. Since we don't have emmissions testing here in FL I can get away with it; and I figure cops ar too lazy and my car is too low anyways to see underneath it to tell if I have one or not. They'd have to lay on the ground to see under there. It helps performance out some, b/c a cat is somewhat restrictive. You can buy better performance cats that are still 50 state legal, but even those are still not as good as not having one at all.

where i live we dont do safty or emmision ether so i dont want a cat. is there any way that they can make it so i can have the cat removable and fab just a straight pipe so i can switch back and forth incase i move

sells test pipes which replace the cat with a straight through pipe.
cheap too

88Mx6GT, is your car really loud...........mine is:E
It has a very loud and uggghhhh sounding buzz when shifting. i doesnt bother me much but ....sometimes its too much
My guess would be the fact that I dont have a cat. Plus my Tsudo muffler isnt the best one. I want to get a 3in inlet Megan muffler.

Maybe go 3in cat-back??

Well I have a hollowed CAT with a 2.5" CAT-back (side exit), and all I have for a muffler is just a little resantor/muffler, Its clasified as a muffler but works more like a resanator. And my exaust isn't super loud, its loud kinda but only when I want it to be....like when im boosting, but if Im just driving slow and I keep the RPM's down its just as quite as stock (well mabey not as quite as stock, but quite enough to say its quite)...I love my exaust.

Mine is loud no matter what, when regular driving its not loud but has a slight buzz at around 2500-3200rpms. When shifting its very buzzy, but when boosting its very deep and makes the car stand out like crazy. Then I shift and it buzzes

Id like to add a resonator, but I dont want to loose flow. Im only running 2.5in piping........

here's what you need to buy to tone it down without loosing performance(maybe only 1hp )http://store.summitracing.com/partdetail.asp?part=WLK-24214

3 inch exhuast from a inch from the turbo with a hayame muffler and no cat, extremely loud, but not in a annoying way, hayame mufflers sorta of remind me of alot of mustangs deep throaty exhuast sound, but in the higher rpm's it gets a bit quiter when ive reached full boost and fly down the road, first time i ever went 3 inch on the exhuast was with my old civic, and i felt like my ears where going to bleed while driving down the highway.
