AMS. The sound is addicting. They will all sound the same. I recorded it with my cell HTC ONE this morning and it sounds like crap. Maybe try to find someone in your area that has one. Videos do not do the justice.

Thanks Boots.
Honestly you cant smell anything inside the car if your windows are up.
If you are driving with the windows down still nothing. Once you pull up to a stop with the windows down it smells really bad.
The sound and the gain alone is worth dealing with the smell and CEL.
I just roll up my windows at stop lights and problem fixed.
Come visit us in Cali and you can see for yourself.

Perhaps but our wives and kids might not like the smell. But then some will say leave them out! I do want to buy dp, don't want the smell, also don't want cel. The inspection is a major concern also.

Trust me, its sickening . Wait till you hear them in person. And that was revving it lightly, hearing the turbos spool up is so hot. I've had them on for about 4 days and have had a ridiculous amount of attention.

The backfires, they're extremely LOUD. So loud that when I first got it it was actually giving me a headache. IM used to it now though . It sounds like a MINI uzzi/shotgun going off.

there are no sick bustards like me around the island

only straight-piped lambos and r8's
