What are the gains for these 2 systems? gas mileage, HP/Torque... For the L99.

Inferno2SSRS · 12-02-2009, 12:59 AM

I'd like to see the comparison of this with the Solo Exhaust too.

I've had Corsa on L99 since June... Don't think your focus should be on gains for ANY Catback system. Been proven to be negligible. MBRP is my favorite for sound but that's on LS3. They worked up a system for L99 after complaints of AFM drone, but haven't heard anyone with it on yet.

Anyway... you'll get your gain with the headers not mufflers...

Ok MBRP is reporting like close to 20hp and even more torque. I for 1 would like to know if thats true. Has any l99 done a before and after dyno run with this system. Or do you know of some one who has posted as much. If it was even 15ftlbs of torque I would get this in an instant.

From independent studies, it has been determined that the CATS are the issue, very restrictive.

On the L99 car that we used for R&D it pulled the best run of 18 rwhp and 22 ft/lbs...the 20-24 was the LS3. This was on mutiple days as well during the months of testing the car with different set ups. Like everyone knows, each car will not be the exactly the same but will be very close.

We run a Mustang 1100 AWD dyno...

was the ONLY thing changed the catback? (no tune tweaking or high flow cats, ect.) My car will be here in about 1-4 weeks and if I would get near those kind of gains I will for sure get this exhaust.

I find that very hard to believe, especially the LS3 numbers. The stock exhaust is already very high flow on those cars.

good numbers there.

when compaired to cost not really..

I see catback more for sound and I love the MBRP sound on LS3 have not heard L99 yet.

Have you seen better catback numbers? It's the best claimed increase I've seen. Mganaflow claims just 11-15rwhp. I personally don't like the MBRP sound though.

Has ayone dynoed either Corsa or MBRP outside of the manufacturers?

I had no baseline dyno, but I have Corsa and dyno'd at 333hp 340tq. That's with an LMR CAI and NO Tune. So I figure about 10-15 for Corsa max. I'm just saying you can spend 1400 bucks and get more HP somewhere else like headers.

IDK that could be like 0-5 for the catback considering you already have the CAI. Some stock L99's have made that much power but every car and dyno is different. Like you said it would be impossible to figure without a baseline.
