Helluva price you got there with an install! Thank God I was able to install my own and save on some labor or I’d probably have spent between $1000 - $1500. that would have put me at around $3000 - $3500 for my trumpets.TSP for me as well, I think they were $1200 installed. No issues.
No fitment issues no false knock, it was Texas Speed Headers. The only real problem is that I bought magnaflow street with stock connection pipes. So the mangaflow had to be widened. Obviously I don't have a certain part for that price, but the drone and the sound is excellent. I am not aware of the installer had to move the AC lines or the engine but everything is indeed kosher.
The advantage to LTH is the scavenging effect. And full equal length primaries that speed up the exhaust flow. Not gonna get that with shorties.I often wondered if lth are worth the cost. I currently run stock exhaust manifolds without cats or a resonator. Without the cats and my car seems to run well; however, I have no comparison. Personally, at the price point would rather upgrade suspension, tires etc. just my opinion.
