LS Engine / Exhaust sound

[renmure]

Newbie owner alert so bear with me here please (and be gentle)

I don't think the 6 litre decat LS2 engine in my GTR sounds as "awesome" as I might have expected. However, I don't really have any reference point for that compared to other Ultima cars so don't really know if that is just how an LS2 engine sounds. I think I was expecting more "loudness" and more "race car" like deep, beefy, head-turning V8 growl.

For context I have a Ferrari V8 with sports cats and a lightweight Capristo exhaust and it howls like a banshee race car and pops and bangs on over-run and the sound is exactly what you would expect if you saw the car, ie it makes an in-yer-face frenetic Ferrari noise. Similarly my V8 Vantage has a sports exhaust and sports cats and it burbles and growls exactly like you would expect an Aston to do and again the big, deep, barking and crackling sound is as big a part of the package as the looks.

Suppose my question is along the lines of.. Is that it? Is it the case that this is the noise the engine makes and that's it? Obviously the silencers are pretty big so I guess removing packing in there is one way to go but are there other alternatives that folk use or ...?

Well, at least I am glad nobody has laughed at me or called me a barrow-boy for raising the subject (yet!!)

I recently spent a fair bit of money trying various exhaust, cats and air filter options to try and get my supercharged Exige to sound better... without too much success really. The exhaust specialist did say early on that the nature of the engine plus the supercharger would mean I could get it louder, but it would never sound particularly nice. I wondered if that was going to be a similar story with the Ultima engine although at the moment I would even settle for a bigger, louder V8 burble.

Anyhow, thanks for the advice so far.. and the youtube links. I have emailed my exhaust specialist as well and will see what he says.

F.C. said:

I had an Exige S with a Larini race pipe, it had an intermediate silencer that could be changed for straight through
Needless to say I removed the silencer, my neighbours weren't too pleased, on full chat it could make your ears bleed!

I know it is OT.. but hey, it's my thread

I have struggled with the Exige. I have tried a few different variations including a Lotus Stage 3 motorsport one, a 6 inch 2bular one, a 5 inch 2bular one and went down the road of having Jim @ 2bular design what he called a custom rifle-barrel system but nothing really sounded particularly nice. Loud, yes but not really nice. To be fair to Jim he did say that would likely be the end result. Suppose that was the essence of my Ultima question in that a previous s1 VHPD Exige with decat pipe and sports silencer had a natural gurgling burbling raucous noise that sounded "just right" and I suppose that's the sort of rawness I want from the GTR.
