Well i might be doing the exhaust work on my SC400 soon, ie near future. I will be doing perhaps most likely 3" Mendrel Bend piping from the manifold straight to the mufflers no cats, well i was lookin on ebay for some mufflers. I like the sound of the Magnaflows 14829's. Now i found these on ebay.
I wouldn't go any higher than 2.5 inch. I would do a true dual exhaust. 2.25inch piping (so you don't lose any low end power) from headers to an x pipe then dual again into the magnaflow 14829's. Couple that with headers, bfi, and a torque converter and you will go from this to this . LOL!
Well the thing is i thought of a supercharger in the far future once i settle down. I wanted 3", but i dont really mind losing low end torque. If i do lose that how much could it affect the car? Performancewise?
Also that sound clip is gone. Can anyone supply me with it?
You will def. notice a loss in low end power. I did a single 2.5 inch piping from cat. to my HKS muffler on my sc300 and noticed a little loss in low end power, but a little better on the top end. If you are doing full true dual 3 inch you will more than likely lose more than I did. PM liveSC400 about the sound clip.
How soon would you be doing the supercharger? You can go ahead and do 3inch if you are doing it soon. But I wouldn't want to be driving around with that low end power lost for a long time.
I guess i'll do the 2.5 inch setup from manifold all the way to mufflers. now about the ebay mufflers? are they worth looking at??? i checked the prices and they are cheaper than from the magnaflow website itself.
If you're interested buying used let me know.... I'll be replacing them next week and putting Blitz exhaust.
Only flaws are some scrapes bottom of the tips from towing.
Awesome news ......a local good shop around my area can do straights going through an H pipe to magnaflows 14829's for around 390 bucks This is also including the 2.5" piping
