aftermarket mufflers for diesels

**ARB** · July 20th, 2003 08:22 PM

many turbo diesel engine cars here changed their mufflers to freemuff's sdg model, the one with the silencer at the tip shich you can get.

woodfire-one of the mods yan ng pajero and other intercooled turbo engines is to change the rubber hoses with tubes that does not collapse like rubber.

freemuff na silenced tip and nakakabit sa kin ngayon. but i was able to raise exhaust temp so high na nagignite yung silencing material. haha. pag rev ko nung malapit na ako sa house may lumalabas na sparks

I changed the oe muff to a freeflow type. No alterations were done with the pipings, still has stock 2 inch. Tumunog bus nga after that. But what I was after is not the sound itself, instead I was looking for a way to release the back pressure. Note: torque band has adjusted for some reason after I changed the muffs.

wat if xtra power/acceleration ang habol,not 'truck-like' sound?wat can be used?and, more importantly, how much? hehe

wulf::: Maraming pwdeng gawin sa kahit anong parts to add more power. (Price range estimated in thousands)

1. You could add turbo to your engine, modify the existing turbo if you have one already. (70-90K)
2. Cylinder head manipulations. (10-50K)
3. Flywheel skimming. (5-8K)
4. Intake and Exhaust performance parts (1K-30K)
5. Regearing (50-70K)

with regards to flywheel skimming, one draw back for this is you will lose engine braking which 4wheelers need when crawling, or in going down inclines. also you can do this if your vehicle is lightened.

one important thing for people who changed to bigger tires is the clutch. you have to change it especially if you have not re geared, look for centerforce brand, they have smooth take-up but gets stronger clamping power once the revs go up.

wulf::: I could elaborate more on me previous post, but then after that I may have to kill you due to some classified infos which can't be discussed, hahaha! Joke, joke, joke! :lol:

Just create another topic with regards to your matters so that this topic will not get out of hand. :D

when i freed my exhaust I felt a shift in the torque band din. when I freed it even further by cutting off all piping from flexible pipe, umurong pa pataas ung torque.
