Okay I have the 18gm DPS along with the Hit Clutch on my 09 Burg. Had a few issues at first, but after changing the pillow springs to the heavier pink's, it has been operating perfectly. Now for the exhaust... have done searches, but no definitive answers. looking for the exhaust that has experienced the best results for people, whether it has been performance, sound, quality, or any other positives or negatives between the two. If you have one on your bike let me know what you think, any info is very appreciated .
