    as some of you know im building a raptor supercharged v6. so when it come to exhaust ive been listening to as many v6s as i can and ive come to realised that auto v6 and the twin 2.5 ill be having sounds really bad. in a manual i like the sound but auto its so so droning its going to do my head in. I think the only option is to try and make it alot quieter. what does everyone else think.

    I know when its out of gear and you rev it it sound ok and when its in full song its ok. but normal driving is the issue

So this time on my ute im gonna get a muffler cause mine is a straight pipe on the auto

    Twin 2 1/2" is too big for a V6, even if it is blown. You really should look at twin 2 1/4" as it wont sound crap like the 2 1/2" will and it will also allow a better torque range.

    yeah that might help or i might go a single 3in. i always thought twin 2 1/4 would be to small but i guess down low would be alot better.

    Use a system that has hot dogs up the front and a straight through twin in twin out rear muffler. No drone and still has straight through performance.

    As it happens, I do just a system like that, not the cheapest in the market but still good value at around $600 shipped. Twin 2 1/2" with stainless tips.

    my exaust was cheap and very worth it

    hi im using muffler called redback, for my cat i punched a hole straight through the guts, so there is no inside to it, straight through, pace maker extractors, straight through pipe at the rear and cut the last box out, all this is 2 1/2 inch all the way through, i have gained ALOT OF POWER, i was 3 car lengths behind my mates vn 3.8, now im 2 in front, so you cant tell me i did not gain any power out of this?

    and MAN IS IT LOUD

    Just happens I heard a V6 VS? with a MASSIVE exhaust just a few hours ago, I swear I've never heard anything more gross in my life lol. I have no idea what exhaust was on it but at WOT it was LOUD and bad!. Must have been a straight through 3 inch with no mufflers or hot dogs at all or something like that

    Twin 2 1/4" won't be restrictive, as that's what i've got on my VS it it puts down a lazy 230rwkw on most dynoes.

    Im running a twin 2 1/2" system on my raptor vt v6 manual, twin hiflow cats and mufflers and its very loud. I told 2 different exhaust shops ill be running the 12psi pulley and they both said it was the best breathing system for a blown motor. Throw a res on the back of it should hush it up a little.

    I have a huge exhaust on my Auto VS and it's really starting to get on my nerves. I just bought the car a couple of days ago and i figured it can be something i can fix later if it bothers me. A friend of mine is gonna put something smaller and less shitty sounding on it. Coz i have 2 kids in my car, and if its annoying me then its probably annoying them. My friend said my exhaust belongs on a rice burner and not my commodore lol. But honestly i dunno why the last owner bothered.
