Default Adding extra roar to the V8

Hi guys,
Couple months back I installed the Injen intake. I was very surprised by the results.
The sound was amazing and I really loved the roar it gave out and made the V8 speak for itself.
But I guess I want more now

I am looking to having a bit more vigorous of a roar. A sound that maybe heard while the car is idling at 2,000 RPM- instead of how the Injen only shows up at between 3,500~4,000 RPM.

I want to keep the Injen intake, but I would appreciate any extra ideas to gain a little bit more sound.
I for sure don't want for it to sound like an old badly tuned Civic, just a little louder of the V8 scream.

Thanks guys.

depending what exhaust you plan to do. good quality magnaflow mufflers could run from $50-150 not including labor.

If you delete the resonators & leave the stock muffler you will get a nice roar & still look stock. Should be between $80-150 tops

Lots of options, from $0 by removing the mufflers(simple unbolt) to $3500 for headers, all new piping and junction produce axle-backs, and everything inbetween.

Mine was roughly $1100 with stainless ran from the center resonator back to magnaflows and custom cut tips to replicate fireball megas.

Nice set up you got.

So is there a DYI instructions on removing the mufflers? Does it require a special tool?

Where did you get those tips? I meant to ask you a while back and completely forgot.

Don't think there's a DIY thread for it, but it's basically a standard exhaust clamp that connects the rear muffler pipe section to the second resonator, located just forward of the rear wheels.

Diesel tips. lol

I had them angle cut to remove the 3.5" inlet for flush mounting to the muffler bodies, and the 18" length is more than enough to give you whatever fitment you want. Mine protrude about 3" from the bumper.

Deleting the resonators produces a great sound on the LS. Cost varies at local shops $50-$130. Still quiet at hwy speeds but makes a nice throaty sound at low rpms such as taking off from traffic lights/stop signs. Highly recommend this exhaust mod.

Will deleting the resonators cause any lights on the dashboard?

Like engine lights or what so ever?

No lights on your dashboard. I also deleted them on my LS400. Minor increase in volume and no drone. Best bang for the buck.
