Big Brown stopped by today and dropped of my 6th catback system for the car.
1. Stock - blah
2. Corsa Indy's - got really loud with the H/C and LT's
3. Ti's - Too quiet
4. GHL Bullets - Got loud with the 403
5. Ti's again - Too quiet and restrictive so I added DMH cutouts
6. LG's Big 3 - a true 3 inch catback
An independent dyno showed that the difference between cutouts and the Big 3 is negligable. The Ti's on the 427 are just too restrictive and the car runs soooo much better with the cutouts open but that's not really practical to drive around.
I've already sold the Ti's and LG gave me a great deal on the Big 3. I'm having it installed at Roberts Custom Exhaust next week. I'm going to Roberts in case he needs to get creative to avoid rubbing the ECS tranny brace.
It's still a fairly quiet exhaust and has some nice tips on it.
