Straight pipe performance

I recently bought a 1995 5spd Powerstroke with stock everything except window tint. I didnt like the lack of sound so i immediatly got it 4" straight-piped. My question is am i losing low end performance? Do i need a muffler to get better low end power? Also as a new owner with a basically stock truck except a TS 6 position chip and a 4" straight pipe side-out, what can i add for more "bolt on" power?

Did you get rid of the factory down pipe when you put the straight pipe in? Also look into the 6637 air filter mod

I would go with a diamond eye down pipe they are around 100. They can be a little bit of a pain to install you will need to cut the old one in half to get it out and bend the pinch weld on the fire wall down to clear it.

I put a Riffraff 6637 filter system on this summer. It is easy to install and well built. I also put on the filter sock. love the sound of the turbo. Great setup. Let me know if youhave any questions on it.

You do not need a muffler at all. It will not affect low end performance. It is a turbocharged engine, so the more flow, the better.

Have you ever looked at your stock downpipe? It is flattened out like a pancake and is very restrictive. Get rid of that thing and get an aftermarket one.

When you decide to upgrade the factory pancake downpipe, find a scissor jack and use it to push your firewall in a little bit. This will save you a ton of time and frustration.
I spent quite some time trying to fit my diamond eye DP in there and it was not going to fit, but as soon as i used the scissor jack and moved the firewall it fit just fine.

Look into aero turbine mufflers if you want even less back pressure after you do the down pipe an get some good custom tunes
