I am looking for a 5 inch in and out muffler for my truck that will quiet down the engine some, but keep the turbo whine, I guess I am looking for a straight thrugh giant 5 inch muffler. where is the best place and what is the quietest one?

 

Call Rip. I never had a muffler on my old 5" system but I've seen that he has a wide selection and can answer your questions.

do you think it would help to put a resonator on there also?

 

If you hate drone they yes a resonator would help. I dont think it would really quiet it down any but it would help with drone. If you plan on putting on a larger than stock exhaust housing or turbo definately get the resonator.

5" straight pipe with a 16cmHX40 droned like crazy, sounded good but after a few hours on the road

 

so if I put a big a$$ donaldson muffler and resonator it will quiet the engine down alot but keep the turbo whine loud?

 

I'm thinking that would work. Might try just the muffler first then add the resonator later if the mufflers not enough.
