| Josh B. 01-12-2010, 04:11 PM I have a 2008 Tundra with the 5.7 v8. I am running 2 Cherry Bomb glasspacks with turn downs. I love these mufflers but they droan like crazy. They are really loud and aggressive. But I need a new exhaust system.I am having a hard time choosing which exhaust I want.I had straight pipes but didn't like the crackling and popping they made. What do you guys prefer that is really loud and aggressive? Josh B. tundrunk 01-13-2010, 09:16 AM Don't you already have loud and aggressive? You will have a hard time avoiding the drone. Perhaps look into these, it is what I run, no drone here. If you run them with less pipe than I have I am sure they will be pretty loud. They make a louder one too, but that's up to you.

They are awesome sounding Josh B. 01-13-2010, 06:36 PM I will look into these. tundrunk 01-14-2010, 10:23 AM They were once popular here. Josh B. 01-14-2010, 02:39 PM How do you think the Spintech Pro Streets would sound with the rear cat delete, only 2 hi flow cats n no other cats,LT Headers,n CAI? tundrunk 01-15-2010, 10:17 AM Believe it or not I have found through experiments I am still conducting that CAI produces drone. When phase one of my experiment is over, I will be posting a thread in gen1 forum, a few members who know are waiting for it. I don't think the cat delete will change the sound, just possibly make your truck run in limp mode if there is an o2 sensor there. I am installing short headers very soon, when I do I will post a thread about it, to add to my experiment thread. The experiment is about changes in performance from CAI, with and without headers. No butt dynos, real science. Should have phase one finished in the next few weeks. Other than that, I think they will sound good. Josh B. 01-15-2010, 03:13 PM ohh. I want to make my truck rele loud n I've been lookin into SPintech mufflers | |
