Hi just wandering how these trucks sound with shorty headers with a highflow magnaflow cat and 3in catback with 2.5in tailpipes with 3.5 x 18in tips. With no muffler I want it really loud. But sound deep at the same time without that annoying *** clap sound that some straight pipes have. Right now iI hav the setup described above with the exception of me having a race bullet muffler instead of no muffler. Any advice or suggestions are welcome. I like to here others opinoins on this matter

 

With a cat still there, it's probably sound pretty good.

 

Yeah I was thinking the same thing. But anyone have a setup like this they could share their experience.

 

Check on youtube. There are a LOT of exhaust sound videos.

 

I've tried YouTube but it's hard to find the same set-up. Also many of the videos are poor quality. My other idea is maybe use a Dyno Maxx race bullet for a muffler if I don't straight pipe it. Is the race bullet really loud and deep. I want loud all the time just not when I punch it.

 

When I cut off the rusted flowmaster and dual pipes, I just had to start it with just the cat and it was stupid loud. Made me giggle but then I threw on a glasspack which helped a little and then a two foot pipe after that dumping right under the bed and that made it a lot quieter. So pipes make a big difference, not so much the muffler, in my experience.

 

Thanks for the info I know dumps are louder but I just prefer the look of duel pipes out each bed corner behind the rear wheels.
what size is best for catback straight pipes. What size is best for true straight pipes

 

I know, I miss my beautiful SS 4" angled exits terribly. But $300 vs $25 was a no-brainer at the time.

You're looking for too specific an answer. There aren't many of these trucks left and everyone has what they like. You'll just have to go with something and be happy. Generally speaking, shops install 2.5" pipes (which I had) but Dodge used 2-3/4". Old school is 2". Get whatever you want. You won't see any performance gains beyond replacing the stock cat and muffler. Flowmaster has sound. Magnaflow/glasspack has performance. Straight pipes are not good on modern vehicles but you could dual pipe it after the cat. Then tune it on the length you want to use. Ever seen a pipe organ in a church? Each pipe is a certain length and diameter to create a particular pitch. Skinnier and shorter = higher; fatter and longer = lower. I guess you could install a pipe all the way to the bumper then cut 1" at a time until you're happy. But you could not change your mind once cut.

 

Thanks ramman, I know what you mean about the price difference my shop wants $400 for cat back muffler of choice and tips.
right now my cat back duals out hallway back the the bed , would it sound any better if it was split into duals directly after my highflow cat.

 

Where it splits likely won't make much difference. 2.5 inch pipe will probably give you the tone you are looking for.
