4 inch exhaust

[383scott]

Has any body tried a single 4" exhaust. If so what muffler are you using and is it really any better than dual 3"?

Mufflex used to have a system using a Spintech muffler. That may have been the best sounding exhaust I've ever heard with long tubes and off-roads.
They still have it.

might actually be too big, how much power are you making, you may loose power with a 4inch rather than dual 3's

Nope, you'll actually see a gain. Even on stock cars.
You may however see a slight loss in low rpm torque, but you'll pickup hp in the higher rpm's.

yea that makes sense about the TQ, but when dragging or street racing , i'd say the low rpm Tourqe is more important than the high rpm hp, well maybe not, idk

also carefull with the axel dumps that kit offers, those are illegal , at least in my state CT

I was kinda hoping someone could tell me they have it and love it or hate it or that is just okay. I know that dual 3 inch sounds awesome and is a big step above dual 2 1/2 or single 3". I have been thinking seriosly about trying the 4" but then I wonder what someone who already has it thinks about it. I will have many future mods and I would kinda like to only have to do the exhaust once. I have also read that it performs well on stock setups. But that could be just a sales hype?????? After all I read it on the mufflex website.
