My VS has a 3 inch exhaust and it sounds pretty sweet, but yeah its kinda massive haha
We had the exhaust cut at the diff once, and it sounded alright at times. Id just go with that other guy. Save your money and a massive hsv 5.7 ltr and just give it some and enjoy the pleasure going into your ears. Or just wack a V8 into the car u got now, probz not worth it tho.
I was considering putting a V8 into my VS when i get onto my opens. Found a 700hp 5.7L with a turbo for $7000, but then u gotta pay for fitting unless ur a mechanical wiz.
Just spend abit on a nice exhaust system, you can get a 2 and a half catback for like $300 from good old ebay if u wanna trust it. I have and its worth it haha
