changing to true duals
changing to true duals well i have the set up listed below and my friends selling his texas speed true duals so im thinking about buying them. from what ive heard the sound quality will be a lot better, but what about horsepower? this isnt a big factor but i was just curious. and how much louder will true duals be?
It will be a bit louder, but the loudness really depends on the muffler and if you dump at the axle or run out the back. HP isnt going to change much either over you current setup.
i have 3 inch true duals with gtp headers and wow.... sitting at an idle, there is not alot of noise at all. i have what i believe are loudmouth bullets, but at wot they scream. so at low rpms my are to bad, but i dont really know what brand they are so i guess i cant help alot lol
The TSP dumped duals are not very refined. There is going to be drone in the cabin, and vibration and low and high RPMs. Many people get sick of it quickly and wish they had saved up for a better designed True Dual System, like the Bassani one. But if you can put up will all that **** you're right you can't beat the price.

If you run them out the back they're really not too loud at all. I saw an LT/X/Sweet Thunder set-up that was super tame at idle. Definitely livable on a daily basis and loud enough at WOT to make you glad you had TDs
LOUD PIPES SAVE LIVES! I saw a sticker with that on a race car and thought it was pretty cool. I have had my true duals for a year now. I put them on last Christmas. I really like them and besides having to remove them anytime I need to lower the rearend I have no complaints. I am running sweet thunders and they sound awesome. The only thing that happens on the negative side is if I am at a light with the AC on I get exhaust fumes inside the car so I shut the AC off at lights.
