Was that with your turbo application? I know they suck when it comes to turbos for sure.

I know that would be the best solution for quiet while cruising around/then max power when you want to put down the hammer, but I really like to drive it at the track with the same setup I drive it on the street with. I like the quieter exhaust for it's stealth factor. Both from unsuspecting opponents to the po po-lol! What exhaust did you have when you did that 12.9.
i ran 12.9 on street 22in street tires time and time again. pulled the caps off my cutouts and dropped to 12.7. thats alot of spinning down the track but consistent. mines a joe gibbs exhaust. with an FI motor the easier the air gets out of the motor the easier it gets in.( more air flow more power) correct me if im wrong.

I have flownasters on my truck, gained 23hp with cutout open, but that's 627 to 650rwhp. Not a significant gain considering you are pushing 800hp worth of air through a street friendly exhaust system. I have the super 40's, from what I've seen they flow much better than the original 40 series, delta 40's, and super 44's, and aren't really loud like the super 44's. IMO, it's more important how well your bends, joints, and merges flow for efficiency.

Wow, that is encouraging. I just need to get this thing dialed in and then drop the exhaust. That will be the tell all...... Thanks for the feedback.

No this was all before the turbo. Im sure it would have been worse with it. You can stick your arm straight through the muffler I have now, and with a full tailpipe its much quieter daily driving with no drone. It does get loud when you stand on it though. I hated not being able to hear the phone when driving lol
