I took my engine out over the winter when my car was being painted. I made a few non performance changes. I also changed from kerry hunter headers with a flowmaster muffler to Triad West Headers and Triad West mufflers. I was happy with my car previously. It was a load of fun to drive however it is way more fun with the current setup. There was a very noticeable power increase. I walked into my home with a very big grin on my face.
This setup is easier to turn than previous. The engine is peppier than previous. Ample low end torque and significant high end power. I'm not even sure if the triad pipes are larger that the KH headers- however I am noticing an obvious difference.
I do have to admit that I liked the sound of the Kerry Hunter/ Flowmaster combo better.
