How can I improve exhaust until I get a full straight pipe?
How can I improve exhaust until I get a full straight pipe?
Also, what size is the stock piping? I am not looking to get into a very detailed job, because at some point I am going to upgrade the turbo with a Euro 140 Manifold and completely redo it.

08-02-2010, 09:40 AM #1I am looking to get a bit more flow and a little better tone until I put a 2.5"-3" on it at some point. What can I cut out and weld a pipe in place of? Cat? Resonator? Muffler?

The resonator and muffler are straight through anyway so there isn't much flow to be had by removing them...
Just don't dump it under the car... I will resonate so bad that you will be changing it back in about five seconds.

08-02-2010, 09:47 AM #2Yup all that you mentioned. Well there is no cat... and the pipe is 2.5" I believe. You can basically get a couple straight sections and weld them in for a couple bucks. Forced Induction did a writeup here: http://www.superturbodiesel.com/std/stra...t-625.html

Mufflerectomy.

My thinking it have a removable tip the length of rear muffler that clamps on. When necessary, I can drop the muffler in place of the straight pipe. Would this work?
Also, since the stock is 2.5", I may as well go ahead and run a 3" which will help once I get a larger turbo and tuned pump.
How complicated would things get if I ran a full 3" straight pipe NOW with stock turbo, and then modified it later when I added different exhaust manifold and turbo? Is there much modifying that would need to be done?

08-02-2010, 10:21 AM #4Ok...seems simple enough. I have access to welding and such. What would be an ideal setup where I can run a straight pipe for performance, but then swap out a muffler when I need a quieter ride?

The muffler is straight through. Just remove the resonator and that will remove 2 ~45* bends. I don't think there is much point to 3" unless you get a myna pump.

08-02-2010, 11:16 AM #8Eventually I will probably get a DervTuned pump with the Floyd 7.5s...in the meantime, what will change just by removing resonator and putting in a straight pipe in place? How much louder?

It will be significantly louder.

08-02-2010, 02:48 PM #13So I wonder if there is any advantage to me just removing the Resonator and leaving Muffler. This is on my 1987 300TDT w/om603 BTW.
