Good points. What were your 1/8 times and speeds?

I agrre with you man. 100%.
[/quote]Yes, there is no reason to expect big HP gains from a muffler. But, also there is no reason to expect the change to a less restrictive muffler to reduce max HP or to do severe damage to the torque curve. There might be a reason for a muffler to reduce low-end torque some, but the comparison of grogan's car and mine fails to indicate that my B&B reduces low-end torque.

I tend to believe the Dinan claims also since they apparently dyno test all their HP-affecting products. B&B's claim may be generic having arisen from "infinitely" many experiences with muffler/exhaust design and swaps.

I've missed the "relivered" part, but grogan is an excellent drag racer, and his un-modded Step 545i is very fast. He has obtained at least one, and perhaps two, 5.0 zero to 60 results and gets through 1/8's in the 8.7's as I recall. I agree with all he says. I mentioned once before that I rolled with a G35, it took quite a while to pass him, but I did so before 100 MPH. He went sooner than I did, and, as grogan indicates, that makes things double hard. If cars are reasonably closely matched, then it is very hard to make up lost .10's of seconds.

I also must have missed the "relivered "???

Thanks for the kind words of support Znod.As you know I am not trying to be a smart ass,but just trying to give some perspective on the subject based on many years of experience.

He's referring to your "relivered 11-10-2003" in your signature Grogan.

davepham671

Maybe you had full tank along with groceries?

znod

Oh, I see. We all misunderstood what 700700 was saying. grogan got a new liver 11/10/03. So, it was him that was "relivered."

GUESSVVHOO

That's the upmarket Nissan? We don't see that in Europe.

I guess it's a V8.

Interesting stats. My diesel does 0-60 in low 6s, and 1/4 mile in 14.2. We haven't yet got a 545i to line up against a diesel Maybe next summer.

It's actually a V6 and to clarify, I'm pretty sure we're talking about the G35 coupe and not the sedan...quite a difference in performance between the two.Sedannnnnnnnnnn peopleeeeeeeeeeeeee

All flaming aside, it is a valid point, I think, that an adult driving a German luxury car who chooses to race some punk in a Japanese car made mostly for little rich kids and folks who don't want to spend an extra 5 grand for a "near luxury" sports coupe, probably needs to get some other hobby.

PoliticalAid007

Yup totally agreed, I think we are all mature and responsible adults, but sometimes we just act like a kid behind the wheels Maybe the E60 make us feel young again.

Edit: Not that I am old, I am not even 30 yet.

I absolutely stand by my comment. If you or anyone is "street racing", you are moron! And, anyone who is street racing deserves and should be called a moron. First, street racing in illegal, and can land you in Prison for a good chunk of time. I think someone who risks going to prison for a cheap thrill is a moron. Second, you can seriously injure or kill innocent people when street racing, which will only compound point one, and devastate innocent family and friends. I believe deliberately doing illegal activities, which can injure and hurt innocent people does make a person a moron.

How in the world can anyone condone ILLEGAL actions, which could result in prison, serious injury, or death?

I rephrased what you said. In the rephrased form, I agree. I sincerely hope you don't mind the rephrasing.
