I have the twin exhaust system on my 65 TR4A IRS. The car has about 85,000 miles on it. The rear mufflers do not match. So I have been trying to read threads about replacements. One I am strongly considering is the Bell stainless system. But I do have some questions 1) Are stainless systems tinny sounding? (a couple of posters said so). Are they any different in overall sound level? 2) Some posts recommended just going to the local exhaust place and putting "Cherry Bomb" type mufflers on. How does that sound? 3) What happens if you remove the silencer under the passenger seat? How much louder and does it sound better without it? Is there a TR6 part that you can use to eliminate this muffler? (Someone seemed to indicate so). I would not mind a little more sports car sound but don't want to shout at my wife at highway speeds as I understand the Monza and some other systems require. Thanks Bruce
