[QUOTE="6speedsd, post: 686611, member: 1242"] After driving her all day, its not as loud as I expected. But I haven't installed my new tip yet either, which I'm sure will make a difference. Biggest change I see is EGT's. Average driving I am a solid 100 degrees cooler than it was with stock pipe. When I put my foot in it, it doesn't jump to 11-1200 real quick like it was before. I buried my foot in it the other day and it hit 1200 real fast and was still climbing. Today, same treatment, 1000 degrees, and pretty much held there for the most part. [/QUOTE]
