Seems like a decent price, what do you all think?

S pipe?
I paid $300 for my muffler delete from the shop that I take all of my cars to..
Included labor and the tips that they made custom for me..

That's VERY steep... I had my own tips, but paid 97$ for labor of cutting out mufflers and welding on new tips.

I just got my tips installed, finally. I've been super busy, so they've been sitting in the garage.

What a treat! The sound is absolutely perfect. It sounds like a stout V8 now, not a standard luxury sedan. The sound while cruising is barely perceptible, but it grunts when you get on it. It's not very loud, but I like that it is understated. Then again, my last car was an NSX running straight pipes, so "loud" means something different to me than other people.

Post some pics or vids man!! I think I want to go this route as well. Sounds like the best bang for the buck for an exhaust system...I wonder though...does this cause more backpressure which from what I understand, will accelerate the chronic secondary air supply problem. As of now, my car has 140k miles and still no problem with the 2nd air supply....hope to stay this way

Search "back pressure" in this thread. That question has been answered about 20 times.......

Again, deleting the mufflers has absolutely no effect on back pressure.

I think if you were behind your car at WOT, your opinion might change.

Perhaps. I took it through a tunnel today, and while I didn't have my SPL meter on hand, it is much, MUCH quieter. The NSX was untrackable at many places because it was so loud (so I later added an electric cutoff). Like 110db at WOT loud. The M5 sounds awesome but is far tamer than what I'm used to.

I like it.

Just had my muffler delete done this past Sat and couldn't be happier.

Went to a nearby muffler shop and got it done for $90 flat! They were really great at catering to how anal I was with the position of the tips.

I love the look and the sound is intoxicating! Makes the car quiet for cruising and a screamer when I give it the beans.

Hands down the best value for money mod for the ///M. Pair this with the Powerchip tune and it's like a different car.

Going to make a video of the sound soon.
