Video please? I know microphones never tell the full story but even a synopsis is better than nothing!

I run catless with Remus mid pipe and exhaust. In Sport+ mode it's loud but bearable and I prefer it that way. It's pretty quiet in non-sport mode. People are just exaggerating.

But if you force the valves open and do a cold start, it's much louder than whatever sport mode does. Hence, fucking loud.

not only loud but it sounds terrible. However it only last for the first 20 secs or so.

I have a DP on my car now. The performance increase is substantial. The sound increase is noticeable, but not in a bad way.

The only time you hear a difference is in higher RPMs. The car sounds great.

I planned on doing the DP then later down the line doing an aftermarket exhaust, but there is no need. The stock exhaust sounds great w the DP.

If you are going to do a DP, just make sure you have a JB4 or some other tune, because you will get a CEL and you need something to reset it every 5-10 days to turn the light off.

You need the EWG and Fuel harnesses for the JB 4 to be able to put the proper settings into the JB4 to make it work right.
