SLP LMII (the new one that came out) is a great exhaust (paired up with UPR X-Pipe). Does its job under heavy accel. but driving at 2k rpms cruising is almost hard to detect you even have an exhaust. Very close to stock sounding in 5th gear at 60.

but what kind of flows did you have, i have a hard time believing that you had 40 series 2 chambers on there and could "barely hear them" they are pretty damn loud.Orions98GT said:well im saying with an o/r h its too loud for me, But I had the flowmaster c/b on it before the o/r pipe was on, it was way too quiet, could barely hear the exhaust.
Really, so if i want a nice sound outside, and no drone inside then i should buy 40 series right?Orions98GT said:it was the 40's series I bought the car with. with the stock h the engine noise was lounder then the exhaust.

I'm going to stick with the Stinger's for a while and see how it all settles out, because it's not that loud.JimTMich said:
Just the regular 40's or should i get super or delta?Orions98GT said:if your going to keep the factory H pipe the 40's are good sounding, but like almost everyone you will change it in the future. So just get a mac or bassani c/b
Super Delta???Orions98GT said:never heard the super deltas![]()
