Default Loudmouth I or Flowmaster american thunder 3'' all the way????

i have a 98 T/A and i dont know which cat back to go with so i thought you guys would know what you like and tell me your opinion between these catbacks so let me know what you think.

i know loudmouth is loud, loud isnt a proplem just how good it sounds and performance wise.

The American thunder kits aren't that great, I don't think they even make them with the 40 series mufflers, which is what you would want if you went with Flowmasters.

Out of those two I would probably go with the Loudmouth.

Actually I just ordered the Loudmouth myself from lmperformance.com.

I was previously going to go with the Bassani tru dual system, but I couldn't justify spending over double the price of the Loudmouth.

It is louder than hell though. My friend has it on his car, and if you don't like it extremely loud then don't go with the Loudmouth.

Also, some people have reported 10 hp gain at the rear wheels on the dyno by switching from the stock exhaust to the Loudmouth.

was also just thinking, are the American Thunder systems even available in stainless? I thought most of them were just aluminized.

If that is the case that should answer your question right there. I would never put another aluminized exhaust on any of my vehicles. I put one on my truck and have had nothing but problems with it rusting out.

Go stainless or don't bother changing it at all.

Why not magnaflow? I am guessing you want something insanely loud if you want the loudmouth? Just remember, your car is not supposed to make people's ears bleed when you go flying past them.

Why not? I take pride in contributing to other people's hearing loss.

Go with a Stainless Works 3" system. They will work with you to get the sound a performance you want. Call them and they are very willing to talk it out and get you the components that will best fit you setup.

Well I have Hooker cat back i love it, especially with my LTs & ORY.

Loud mouth sounds good on stock set up, but with LTs & ORY it is very LOUD! even with cats for some people.

TSP rumbler sounds good and price right too. http://www.texas-speed.com/shop/item...d=195&catid=46
