4.2 Petrol / 2 1/2 inch straight through exhaust too loud?

Post by BrentE »

I currently have 2.5inch exhaust with muffler (huge) and hotdog at end and want too get a better note/louder note.

Would 4.2 Petrol with LPG (TB42) 2.5inch straight through exhaust into hotdog/resonator be too loud? Or under power 4wd?

Any replys would be awsome thanks

I have the same minus the hot dog, not to loud compared to some I have herd but still a good note and loud enough when giving it a gut full that is allmost silent when cruising on 100k doesent drone. I think strait trough would be way to loud and droney I would get the hot dog removed and see what you think if still not happy get a smaller muffler fitted.

I have 2.5 inch mandrel bent. I had it straight throuh and it was way too loud. The crackle an pops were really over the top. I now have one redback "S" shape muffler and its much better.

blew the baffles out of my SWB muffler and got it replaced with a piece of pipe. (2.5in all the way). Sounded awesome, but was very loud. Could hear it 2 odd km away going through the gears....let alone giving it hell!!!

Unfortunately power lacked and fuel usage went up marginally, so a straight through muffler went on.

Dont think i got any videos anywhere

keep at least a muffler in it, so you have back pressure for down hill....
