A quad exhaust on a 528, why? Im mean it will look nice but performace wise you may lose power.

 

Wow, After the Alpine White your cars blue color is bass ass. I love that color. What a beautiful car. Ok guys correct me if I'm wrong. Umnitza exhaust quad is just an addition to the main muffler. I imagine that the main muffler get about 80% of the gases. The secondary outlet is just for looks. That's what I'm looking for. Power isn't my concern. I don't race any more. I just want to make sure that when I go to local Walgreens down the block I look good.
I don't worry if in cold or winter all I get from the secondary is just little smoke coming out compare to the main muffler. My primary concern is that it sounds good. According to the video it sounds great. Just to hate a little I would never install a custom system with American made mufflers in a non domestic car. I can't imagine the sound. I guess it would be to loud or you might get confuse with a noisy truck coming down the street. lol

 

People like to talk about the power loss on the 525/528's doing quads. But unless you're dyno'ing and care about that bit, (in which you wouldn't have gotten the 525/528 to begin with) the power loss is negligible at best.

Exhaust change will most likely change how the power delivery is, but mid to top end, you're gonna get the same thing more or less.

 

Exhausts that we've installed on 2 cars that were actually dyno'ed are listed on this site somewhere.
Dyno showed up to 6-9HP gain and 0-4 TQ average gain across 3 pulls. so as long as there is no loss, you save weight, get better look, and much better sound.

 

And this is with a quad exhaust on a 528 right?

 

Ah... Ok. I'm down in RC-S. So I guess we aren't in the same place after all. Guess there will be no support meetings for this addiction anytime soon!

 

yes.

 

What FOB are you in?

 

Ok Gents, Now that we got the muffler power loss question settled, lets talk about Angel Eyes. Ever since someone here on this thread suggested to look into Umnitza Orion V4 I got into research mode. Any input will be appreciated. Please feel free to add other manufactures options.

The Lux V4's are nice if you're looking for a straight PnP (had the Lux V3's for a year). However the Orion V4's are the way to go. Not a fan of the multi-color AE's but if that floats your boat then go for it.
