Larini Muffler on LP670, what to do with primary and secondary cats?

I finally found an LP670, and am already wanting to make it louder. It currently has the Larini muffler on it. So, the question is:

 

1) Do I go with Larini primary hi flows? Or just get a delete? Will an IPE primary sound any different, and would it even work with Larini muffler?

2) Test pipes for the secondary cats?

3) Bite the bullet and get an IPE or Kresseig?

 

Thanks for the input guys, I'm just starting my research.

 

P.S. - I have the Larini Club Sport valved mufflers for my Performance, which sounds way louder than my SV Larini muffler. Not sure why?

 

 

Kreissieg is the best sounding exhaust for this car, IMHO. LamboNutter has one on his and it's orgasmic!

I'm not sure what the CGT quote was about above your comment, but I wouldn't sell mine for $700k

 

I wish I could hear the Kreissieg in person. The IPE sounds great. I'm just wondering if I'm better starting all over or just building on existing Larini.

Ah, sorry about that. It must have populated from the last thread I was in. Darn, haha.

 

If you want louder, why not just put test pipes where your cats are? I believe that WHITEOUT has gone catless. I'd check out his Instagram @ Lamborfuckinghini. I think he has a few clips of his car on there.

I'm definitely going test pipes for secondaries. Thought about it for primaries, but heard that I may have power loss if I do that with the primaries.

I have Kerissieg on my 2007 LP640. My favorite exhaust so far.

Who is the preferred Kreisseig dealer? Price is double IPE.

 

Does anyone know for sure if primary delete affects engine power? My preference is loud, so having both primary and secondary test pipes is tempting.

If I were you I would go with IPE and delete Primary, delete Secondary all together. A little power loss not gonna hurt a thing with all through straight pipes, but the sound is going to be out of this world for sure. My LP640 with Tubi and primary/secondary cats deleted and it sounds good but my ultimate set up got to be IPE with straight pipes

On a second thought...just pull your primary and secondary cats out and run Fabspeed straight pipes (not high flow) and see if your existing Larini exhaust sounds good enough for you, if not then you can do the IPE. I have no CEL with straight pipes

I think Graham has an IPE hookup here, locally.

I believe T S M is set up with Kreisseig.

On my friends 670 he has the IPE with primary and secondaries removed, I haven't driven it however we have had some spirited runs next to each other and I sense no power loss.

 

As far as sound, while idle and under 3k it's actually more subtle then my setup which is secondary removed and a aftermarket exhaust that we can't figure out what brand it is. Anything above 3K it starts to come alive and sounded nice, he did mention he smells the raw fuel which isn't appealing to me when both cats are deleted.

I have a short clip of Kreissieg on my LP640 @ idle. I'll try and post it. I like the deep sound.

I am personally done with catless cars. The stink gets in your clothes and hair so you get to smell it all day. And the chicks will hate riding in the car.

Ahh, thanks for the reminder. I remember my Viper days, it smelled terrible.

 

Looks like I'll be trying the IPE or Larini high flows, secondary deletes, and keeping me Larini muffler unless someone local wants it cheap

Honestly, just remove your secondaries first before chopping up the whole thing. You'd be surprised how much sound it adds and you don't have a stinky smell, to boot!

You and Ted can do a reverse bidding war! I'll buy the cheapest one ;p

Not a bad idea, especially since I already have the test pipes for the secondaries. Anyone know how easy it is to change them out?

Secondary is very ez to do, but not the primary.

 

If I remove the secondaries and replace with test pipes (leaving stock primary cats), how does that compare to replacing the primaries with high flows AND secondary test pipes? Are secondaries only a fair representation of how the Larinis sound? How much more volume and does the pitch change when stepping up to high flow primaries? I already have access to test pipes, would have to order high flows.

 

If I don't like sound with Larini and test, I may skip the Larini primaries and just replace the whole thing with IPE. I'd hate to get high flows and still hate the Larini sound.

 

I can't find any videos comparing the larini alone, larini and test secondaries, larini and only primaries, and larini with both primary high flow and secondary test.

If you want LOUD, delete your primary cats (will also produce massive fireballs.)

 

 

 

Since your car has Larini, are you sure that your car doesn't already have secondary deletes? Deleting secondaries is very common when changing the muffler. The primary delete & secondary delete will work with Larini.

 

A good option for you if you're unsure how loud you want the car is to add primary deletes to your current system. When the exhaust valves are closed, the exhaust will be louder than it is now (but not crazy) and when the exhaust valves open, the car will scream. At that point, if you want it louder, then switch out the rest of the exhaust. If you're happy, you just saved a bundle.

 

The sound that everyone loves in these systems is a result of the primary delete.

I'm definitely going test pipes for secondaries. Thought about it for primaries, but heard that I may have power loss if I do that with the primaries.

Deleting the primaries will gain a significant amount of power and noise throughout the powerband.

 

The design of the exhaust after the primaries controls the type of power delivery, a shorter exhaust will have more top end power and longer exhaust will have more low end power. I swapped from RSC secondary & muffler delete to DTP (much shorter) and there was a power loss at very low rpms (driving slowly), no noticeable change in the middle of the powerband and power gains once the secondary cams hit.

 

I've had the following exhausts with primary deletes: LOC/LNB, RSC (quicksilver) and DTP. With primary pipes in, they all sound great. With primary deletes, the LOC has a nasty drone throughout the powerband (excluding WOT) and RSC has a bad sound around 1500-2k rpm. DTP has no drone, but is super loud.

Awesome post Whiteout, love the videos. While I'd love to go full primary deletes, I already have a hard enough time convincing my wife to ride in the car. Without cats, she'll never get in it. Have you ever installed a secondary delete while leaving primaries in? How about compared to primary high flows and secondary delete? I have access to the secondary delete pipes, but am trying to decide whether to install those first or just get the primary high flows and install both at the same time (it's a bit of a hassle to get the car serviced, so if I can avoid two trips that is preferable).

 

My fear is that if I don't like the Larini sound, I'll have to remove everything and start over with the full IPE exhaust. Anybody want to buy a Larini muffler? If I pre-sell that, my decision might be easier.

IPE will remove the primary cats. So it won't be any different than Larini with valved primary cat deletes.

 

Kresseig, Larini and IPE are high flow mufflers.

LOC/LNB, DTP, Fabspeed, RSC and Quicksilver are muffler deletes.

 

So your car, with Larini, will be quieter than the muffler delete systems. If you get a valved primary delete pipe, it will be louder, but not crazy loud like the muffler delete systems. Further, the valve opens up at full throttle and bypasses the muffler (factory design) so Larini/Kresseig/IPE won't sound much different.

 

If I were in your shoes, I would do Fabspeed primary cat deletes with valves and keep your secondary cats and larini. Keeping one set of cats in keeps the exhaust note reasonable (the same as if you deleted secondary cats), which your car will be driving around with your wife. But when you open up the exhaust valves, it will SCREAM, shoot fire, and pick up power.

 

IPE offers just the muffler, so you can swap that too. You don't need to re-purchase primary delete pipes. IPE muffler section deletes the secondary cats.

 

Primary install is a PITA. The rest of the system is easy to change at a later time. Here's a picture of my car (with RSC) as an idea of how easily accessible the secondary cats and muffler section are:

When you say primary cat deletes, you mean a piece of pipe with no high flow cats in them, right? What are your thoughts on the benefits (power or sound) of changing to high flow primaries instead of deleting them altogether? Primary high flows coupled with secondary delete, that is.
