ronnie said:From the switch of 3" to 4" on a L, there was a 50 HP increase. I would expect even more from Cobras since you guys have better flowing heads. But, let's leave the 4" downpipes to diesels and Lightnings. My bad. You guys know something I don't. Please let me know.
I bet they would see some additional hp going to a 4", maybe not 50 but I'm sure it would be benefitial. Where's CPE we need him?
