I realize the cam has alot to do with it but I'm about to redo the exhuast on my lq4 swapped 77' 280z and I'm after the crackle that I hear alot of vettes spitting out. What is it about the vettes that make them sound so badass? I'm building a dual 3" system with an x pipe and magnaflow race series mufflers. I currently have a .590 .590 114lsa cam so nothing crazy.

Big cubes, big overlap, and Corsa. Corsa amplifies the crackle you hear.

Concrete floor garage and a cam, IMO.

LQ9 EPS cam specs 600-ish lift and 233-ish duration that went into my buddies 78 Caprice (Christine).

does anyone know what model corsa mufflers are best?

a big cam and tons of compression is the main reason, the rest of it is a x pipe and basically equal length pipe with minimal bends. bends kill sound quite a bit. If you build a nice system with an x pipe you can get good sound in the Z

here is what my setup looks/sounds like so far, it should be perfect when I get the rest put on there this is all that is on it in the video

This trans am sounds pretty badass too, gives me hope

yeah man that thing sounds amazing! what mufflers are you going to go with?

well the bumps on the piece above are these 9" dynomax bullets

will be doing a set of full size 16" bullets in the back to quiet it down some

Have used a setup like this before and it works perfect, the small bullets that far forward do more than you would think

the x pipe is an ebay piece and its great quality for cheap, overall this is a cheap setup all the tubing and vbands are from acestainless.com whom I also recommend. the entire exhaust system is stainless from heads to tips. I think I have about $800 in it including headers, mufflers, all tubing, x pipe, etc.

you running long tubes? having long tubes in an LS s30 is a nightmare and very expensive.. like $870 expensive. I cant justify $900 over shorties but i bet it makes a big difference in sound.

I like the idea of using the bullet mufflers, They are louder and sound nice. I bought a set of magnaflow race series mufflers and they are huge and sound like a truck..

Grr

yeah I made a set of 2" longtubes





I had been planning a 280z for the last 2 years so I know what you are talking about, but I just couldn't find on that wasn't rusted to **** for a decent price around here. Plus the FB was cheap as **** couldn't pass it up

biggest thing with bullets people never get is you need as much pipe after them as you can get. If you run them on the end of a pipe they don't do very much. That is why even the small ones way up front like that work well.
When I add the longer ones in the back I will have at least 6" after them if I can fit it

yup.. lookin good man. Finding an s30 that isnt covered in cancer is a challenge. I really wish i could get my hands on a set of long tubes. After seeing your pics i might try to sell my shorties and bite the bullet. 10-15hp difference is what i hear and i bet they make a big difference in sound.

only thing with the s30 platform is the lack of room. If i mimicked your setup i would have to run the 16" bullets and the very most rear part of the exhaust system.

That does sound good. I wish I could find someone with one of those test stands around here, that would come in handy.
