Exhaust gains?

[Big Mike 74]

2013 pp with 93/v8 lms tune 3 bar thermo and plugs, what exhauat is the best around for performance gains and what kind of gains should I expect to see hp wise from it, or should I just get catted down pipes and leave the stock exhaust.... I'm looking for a little more power and am assuming my next outlet after tune would be exhaust mods

Your next mod (in my opinion) should be the downpipes. You really want to get rid of some of the backpressure on the impeller. Doing so will result in the car making far more efficient power. Basically you want the car to work as little as possible during power creation. Allowing the turbo to spool with little resistance will make your car a killer off of the line!

Yea I was thinking that I think I'm just going to do your catted downpipes with my stock exhaust, what kind of power gains do you guys see with the catted dps?

 

[Livernois Motorsports]

There are gains of 10-14hp. Our race catted catback exhaust is going to help, but if it were me I would want to keep that sleeper advantage!

Yea, do you have a clip of one with just the downpipes and stock exhaust? Or from experience how does it sound ....I still want it fairly quiet when I'm cruising around

From experience, it is fairly stock sounding until you lean on it. Once you start to build boost at a good clip the turbos really wake up.

Either way you go, catted or non...both will sound almost stock if you don't touch the catback system.

Okay thats good for me because I leave for work at 4 in the morning lol....I just wanted to make sure I would get a power gain mounting them to the stock exhaust

Forgot to ask.....does my tune need to be updated with the downpipes??

 

[SHOdded]

Only if you want to take advantage of the downpipes

Yes, it does.

 

[jtreber]

Yes, it does.

Hypothetical: If I should need to take my '15 in for warranty and put the stock tune back in, would these 02 extenders work with my Livernois DP's to keep from triggering the check engine light? http://www.355nation.net/forum/how-...fouler-eliminate-check-engine-light-pics.html

 

[Livernois Motorsports]

That is not a question for me...I am positive that someone here can assist with that. Sorry.

No problem. I was just thinking since the Livernois DP tune shuts off the rear O2, your engineering might have tried this with a positive or negative result.

 

[Livernois Motorsports]

I just cannot advise you on the extenders regarding emissions.

We do not simply turn off the O2's, we actually tune for the addition of exhaust mods.

I had my DP's and tune installed at Livernois. Can you tell me which o2 sensor (sensors?) are disabled?

 

[Livernois Motorsports]

The rears are tuned out.

Does this cause a check engine light?

I had the same concern. My younger days has had its fill of loud cars. I can hardly tell the difference with the Livernois DP's other than a 1 second throaty sound if I lean into it at a lower rpm. Not being familiar with turbos, I was guessing this to be the turbos spooling up earlier.

you have those mounted to the stock exhaust tho right? Also howz the power gain with them I'm assuming you run them with the tune
