I couldn't agree more Sam. At first i was like Holy Cow this is loud. But now have really settled in to enjoying the sound. The only time it annoys me if anything is on a long constant incline on the HWY.

Otherwise i am loving it. Also is it possible that James having the 7AT could be a contributing factor. I'm mainly thinking due to the gear ratios, possibly keeping it in a different Rev range to the 6MT.

As above, also need a bit of time for it to burn in, which no doubt James has done by now.

Now from what i heard and read about the exhausts, the FI cat back is actually louder than the stillen, so if mine is loud with cats then I'm sure yours will be a bit louder on top. Do you know anyone who has the cats installed? or did u all get test pipes. Would be good to hear it first...

Videos on youtube etc are of no help in my experience...
Would so love to see some DB readings on these exhausts thats for sure, i mean across the board that is. The other thing about HFC's is that they will give a different Note as well (correct me if I'm wrong).

Agreed on the YouTube videos also. Sam's vids tipped me over to the Resonated Test pipes and they are no where near as loud compared to real life.

I would say IMHO if you want some videos to get a good idea of what the RTP's will sound like have a look at my YOUTUBE videos i added few days ago. They will give you a good idea of what to expect with the RTP's along with full CBE. The main ones would be "Driving Around", "Mountain Run" for inside volume and "Drive By's", "Launch" for external volume. Also if possible listen to it with some OK speakers atleast and the HQ versions.

BTW Good luck James.
