Screw it...getting 2nd cat/muffler delete this weekend.
#16
Ryan If you do this it'll cost you more than a few $100. There's no point adding resonators because the existing one that comes with the stock exhaust is preserved. A simple 2nd cat delete and muffler delete replaced with stainless steel pipes will suffice. Getting rid of mushed Y doesn't do anything. My setup doesn't sound raspy at all when warmed up.

I get props ALLLLLL the time for the sound of my car. I still have my all my cats on. I just removed the mufflers and rear resonator. I get the thumbs up from fords, vettes, trucks, bmws, whatever. The ONLY person that has every consistently said that "it's too loud" was Blitz_714 LOL.
So, now I'm really interested in doing a muffler delete. What exactly do I ask for if I go to a muffler shop? Do I just say I want a muffler delete and for the pipes to run straight to the quad tips? What piping (type and size) should the muffler shop be using to do this?

Any sound clips/videos?

^^IMO that m5 doesn't sound like anything special. The E60 M5 with aftermarket exhaust sounds way better. If it wasn't for the abysmal gas mileage and crappy reliability I would have considered the E60......that V10 is just sublime to hear.
I passed inspection with my setup. No CEL's as long as you don't mess with the primary cats in the headers. You can pretty much cut off everything after the o2 sensors and not throw any codes. I did an extensive video with all driving styles and it is not loud at all under moderate load cruising at 70mph.

I don't think I care if I can put back the mufflers if it turns out good. However, I am a little concerned it maybe too loud or obnoxious. I daily drive my car to clients so I want something more deep roar as opposed to raspy. I love the sound of the Joe Z exhaust; just looking for a cheaper alternative.
VtotheJ - I didn't realize you had to order parts, I thought you could just take it to a shop and they would weld on a straight pipe. Good thing I asked. Thanks.

My F came with a muffler delete on stock exhaust when I got it. It is loud but a very unclean sound. I raced a stock F several times and was left by two car lengths in the beginning due to the low end torque. After getting my Joez exhaust and took out the 2 nd cats, and it felt like the HP/and torque jumped dramatically, along with a more sporty sound. I feel there was a large loss of power with the muff/delete. The accelerateration is smoother and faster now. Last year I added PPE headers with high flow cats. The sound is incredible! It obviously is even faster now, but the diff in sound quality from the muffler delete is night and day. Makes me want to warn anyone from doing the muff/delete IMHO. Cheap sound but terrible power loss.

A stock ISF left you by TWO car lengths? Jeez, you must be the needle in the haystack. Were you in Sport + M mode with VSC/traction off, while shifting after the beep? The car is nearly 60lb lighter and has restrictive components of the exhaust removed. If you looked through the OEM mufflers and secondary cats you can see how restrictive they are.
FWIW I ran with 2 ISF's that had full bolt-ons and it was dead even. 40-60, 40-80, 40-100. I would imagine top-end they would have me but I'm not sure by how much. Before telling everyone "terrible power loss" you should back it up with dyno numbers, before and after the mod. Also take your car to the drag strip and see what you run. I'm not directing this at you, but full boltons are a waste of $3k if you don't know how to drive.

I have no money issues and I went the exhaust mod route. Why? Because $1k+ is a waste of money for an exhaust that nobody sees (besides the $2K+ ISS forged exhaust). Also, the majority of us don't take the car on a timed course to fully exploit the benefits.
Ignorance at it's best... s4play do you have statistics on the age of people that do this? Probably not. "Younger crowd" is also subjective term. The ignorance of people here kill me, LOL.

To each their own. Almost every single F has joe-z/borla/ISS. Muffler/cat delete is a unique and raw sound, and it doesn't sound cheap at all. I get compliments from everyone, super car and sports car owners alike.

^That's a nice power jump, I am interested to see what you would run on a drag strip qtr mile (closed course). A dyno is good to show if mods actually increased power, which in your case it did. As everyone always says, including forum veteran Lobuxracer, the best performance mods are made to the driver. Around a track, he would probably beat most bolt-on ISF's on here in his bone stock ISF, since he doesn't believe in mods, rather how to be a better driver. Let me tell you, at the ISF mega meet in April I got to hear a bunch of bolt-on ISF's with diff combos, and it sounds amazing. But is it worth $3-4k? Nope...I don't track the car regularly. The power we all have in our F's can get us in trouble already.
