I've researched individual setups with mixed results. Everytime I talk to someone I hear the same answer, SG makes a badass Longtube setup and thats what you want.

XERD or their current Megan replicas are on the short list of things to try.

Currently I have a set of TopSpeed & Stillen Test Pipes.

The motor will be 11:1 with Kelford B NA Cams & PNP with stock sized Ti valves, and BC or Better Head Pkg and simple street cut valve job. HR HG & Coolant Mods

I don't want to buy multiple setups, and only have the TopSpeeds laying around from my BP Single Turbo setup.

Power is important but sound is equally so. Volume isn't the main concern as much as tone. I am obsessed with high revving NA v6 engines like the F1 cars in the early 80s.

Options, please join in with fact backed opinions. The Exhaust I will be running is Exotic Speed R1-T

8500 - 9000K Redline is the goal with heads to support it.

Top Speed Headers w/ Art Pipes
Megan Headers
or Just sell my soul for a set of SG Longtubes.

 

Unless something's changed, the SG longtubes are no longer in production.

 

I think the SG might be hard to get now, but it's always worth a try to give sasha a call if you are serious.

Have you heard the motordyne single exhaust? It's not the hottest looking thing but the sound might be what you are looking for. You can also swap out the axle back for any of the new ones that are available on their dual system too.

I personally run the motordyne exhaust on my na motor and i love it.
