Muffler / Exhaust

[JMNY]

Custom installation was done today and I love it! Nice sound, nice custom chrome tip, but by far the difference is the power. My Muffler was in bad shape - worse than I knew - I cant believe the difference in the performance. A new exhaust/muffler system should not make that much of a difference - but it did!
Very happy - and thank you to everyone for your input/advice!

I was talking to our Isuzu guru Jerry Lemond last summer, who mentioned the strong possibility that our mufflers have a warm-up valve inside. But he couldn't confirm it...nor could this forum.

If there were one...and it were stuck, it might explain an obstruction severe enough to cause a pronounced improvement.

That would make sense. I cant describe the change in power enough. I have not driven a VX in 10 years - so I dont remember what it should be like - not to say I know now - but I am happy with the difference in power and the sound.

I sold Blacksambo a virtually new OEM exhaust ....
