that looks expensive... $$$ plus what are the real advantages of actually having dual outlets like that... besides looks?

Peter if you dont have duals yourself you probably cant answer that question accurately. I first had only one muffler and put the other one on later and there was a noticable ammount of power gain through the mid and high rpms. All im saying is dont assume unless you know for sure.

Also i might comment that one other advantage of having duals to me is the sound. Having had single and dual exaust on my car i like the sound of the dual better. Obviously if you put another muffler on, its gonna change the sound a little. To me the sound is a lot more in tune instead of a loud farting sound like it used to be before. Again this is my opinion, take it for what it is worth.

yeah, i know i dont have one, but i just wanted to give him the answer other people were giving. it's been asked before and im just restating it. btw, u have a lot of other mods which might be the reason why the dual exhaust helped, but for a solara with little to no mods, i dont think it would help any...but then again, how would i know? i dont have one...

I would say the gain on dual exhaust is minimal or perhaps none.
It may give a better sound, which make us think that it gives a better gain.

Most High Performance cars would convert back to single exhaust.
I am talking abt 300ZX and 3000GT.

I have never seen Supra w/ dual exhausts either.

Perhaps you can give us some dyno pics to verify your statement?

You're exactly right. Its additional weight. What you free up in HP for the solara would be lost in extra weight. Now on pure muscle like a vette, thats where dual exhaust header back, not cat back really helps

Sorry i have never dynoed my car at all so i cant provide you with any numbers, but in my opinion, the duals were worth it. The person who started this thread wanted to know if it could be done, and i just wanted to help him out and let him know that it has been done by me and several others. Maybe the others with duals can comment about their performance gains or losses with the duals.

See I can see from an asthetic standpoint why people would do dual. But since i'm one of those picky ones...I couldn't live with the exhausts not being symmetrical i.e. tire well offset to the left.

I have probably done more testing on the 1MZ exhaust then anybody. The 1MZ is SUPER SENSITIVE to changes in back pressure. With just altering back pessure alone I was able to gain 16hp at 3k rpm at the expenise of 5hp at redline. You can totally change the way the car feels by changing the amount of pressure in the exhaust. The exhaust can also dramatically alter your a/f ratio. Just something to think about as you guys play with your exhaust.

hey...can i comment...i guess i can cuz i have the duals...first off when i did the custom cat back exhaust(single, 2.5" piping)about 1 1/2 years ago i DID notice a considerable amount of pressure being kicked out of my ride...later about 4 mnths ago i did the y-split to dual conversion and yes im positive the sound changed to a more mellow deep tone, however power wise it did not change...and i have to agree with aggy on the fact that most cars after being performanced tuned would rather go back to the single exhaust...i by the way did my conversion solely to compliment my body kit...by the way...is any1 else having problems uploading pictures to their cardomain site?...L8r, moe :evilbat:

moe, cardomain is just really slow, u have to keep trying. it took me a couple tries, but it should work. they're always slow

My point exactly! Thanks for re-establishing that Eric.
