I want to retain it because even if this part of the exhaust is restrictive, I'm not going to feel a difference when replacing it, unless I'm on a timed course, which 99.9% of the time I am not. And to be completely honest with everybody here I did the mod for the sound, nothing else. I'd be lying to all of you if I said the car is "noticeably faster". All I know is that the V8 is alive, and I love the sound of it and so do other car enthusiasts.

What do you think that costs us as far as HP goes? 1-2 HP? Come on who cares? I'm willing to bet we still pick up 5-10 HP and lose 50-60lbs of weight with the cats and mufflers gone. But, it's mainly for the sound anyway. If we all were concerned about picking up a measly 15hp (that won't be felt anyway), we would've dropped money into proper exhaust.

OK, OK you guys. I thought we had a Performance Car, not a car made to produce noises you think might impress people Me, as I have said many times, am interested in performance first, but want to keep noise in check. Third party systems are all much too loud for me and your, excuse me, ghetto systems are even worse. If all you're interested in is the sound your exhaust system produces without regards to improving performance, than I am clearly in the wrong thread I will not post to this thread again

But, as far as added power not being felt, your are wrong, dead wrong

Just because I shelled out way less money to have my car sound like a true V8 it's ghetto? LOL. Why would I spend over $1K for an exhaust that yields 15HP at best? Why don't you track your car, print out the numbers and post back? And IIRC you must have headers too right? Another over-priced mod... although your numbers should be significantly better than Lobux's right? I'm not saying it's a competition, we need a baseline to compare to, so use Lobux's numbers as a baseline, since he's all stock.

Also, you did post in the wrong thread, the OP didn't ask you to lecture everybody on why the "crush part of the exhaust is so restrictive".

I believe that that restriction is the most important part of the exhaust. IMO, the added back pressure(lobux will probably correct me on the theory of pressure within the exhaust) caused by this restriction is why the secondary cat/muffler delete ISFs are faster than those with full exhausts.

I know exactly who your talking about know. Ill send you a pm

IDK where your reservations come from about the secondary cat/muffler delete, but I can guarantee you that the performance side of it is actually second to none when it comes to exhaust systems for our cars. I have never raced another ISF that has exhaust work and had it stay within 2-3 car of me. And from what ive read/heard, the experience is similar for those who have done the deletes and raced other ISFs.

Lance's comments on the crush when comparing to an eBay mid pipe:

Then im confused as this seems to be the stock exhaust pipe up to the Y.

VicTornin

So, if I delete the PTS mufflers from the Joe-z System, the car will perform better??

MRxSLAYx

Not necessarily. I believe that the 2-1-2 setup is ideal for our cars that are all motor. The Novel system out of Japan is actually near perfect.

the exhaust is kinda quieter. not sure if weather makes a difference because it was really cold today and the day i put it on, it was really hot.

Different strokes for different folks. Obviously, the F is nowhere near the fastest car on the street and even fully modded it still doesn't get there. I didn't buy this car to be able to "beat" everything in sight. I would've kept the GT-R. This is a fun car that is refined, but in reality it feels like a dog compared to what I was used to. I'll never get the excitement out this car that the GT-R provided no matter what I do. Doesn't mean I don't like to tinker around with it and I actually absolutely love the F. Who really cares about 15hp? Or 50 for that matter. Still won't do it for me. I remember adding 50hp to the GT-R and being disappointed with Cobb because I couldn't tell a difference. This started a large discussion on nagtroc and Cobb stepped up to the plate with some new beta tunes that made a difference. I ended up with about 115-120 more HP to the crank from a custom tune before I could notice a REAL difference. So, if you can feel 15HP, then you are much more sensitive than I. My point is that not everyone on here is after that last 5hp. Some like the sound. I know I do.

Honestly the stock exhaust is really restrictive just to help increase gas mileage. I think it's closer to 25hp. I am going to dyno my car and try something new. I'm going to build a single 4 inch exhaust with secondary cat delete within the next month. I will post results when I'm finished
