Thunderbolt Mufflers?
I have a guy who is going to install my gt takeoffs and he suggested that I buy Thunderbolt Mufflers since they are a knockoff that is cheaper than Flowmaster. Anyone ever hear of them? What should I do?
Ive never heard of em. I think the stock GT mufflers would be fine for a v6 based car, no need to spend the extra money on other mufflers.
Personally I think the stock GT mufflers have a nice smooth deep note to them and should sound good on teh v6. If they are like flowmasters, they are chambered and may not sound right.
