Exhaust choice to tame down cam lope
Hi guys,
I know that most of you must love the cam lope sound, I did as well but I just don't like it as much anymore. I'd like to have a car that sounds a little more stealth with a smoother idle.
I have a built 408ci, I have tried the bone stock exhaust. I really did not like it as the idle was horrible and as the exhaust is very quiet I had that sewing machine sound from the valvetrain while cruising. Did not like that.
I tried a set of B&B Bullet, they were loud as hell, however I couldn't hear the cam lope, the sound was much smoother. So I can they they partially delivered what I was looking for but in a very loud way lol I had to remove them as I did not like to look on my neighboors faces
I now run a GHL Bullet exhaust. It is not too loud, I really like it, but it still has that loppy idle that I would like to get rid of.
If any of you has heads/cam or built motor and an exhaust that could meet my criterias don't hesitate to chime in. I am thinking about Magnaflows??
Thanks in advance

How big is the cam?
Anyway, there are adjustments that can be made to the tune to mellow the idle a bit.
Airflow, timing and idle speed.
Ask your tuner ?

The cam is a 238/242 on 115+3 LSA
By stock exhaust I meant LS1. I never had a chance to try the Z06 Ti. I have only seen vids on youtube and they seem to sound like a motorboat with a cam, a bit like the corsa. That's exactly what I want to avoid. However I also know that it is always better to hear it in person. Unfortunatly there is no way for me to hear it around here
The only thing I don't like about the GHL is the sound at idle. However the car runs great at idle, very stable. The idle is set at 900 rpms. So I wouldn't think that tuning it would change much. I am sure it could be helpful if the car idled really badly. I heard some H/C cars that almost stall when at idle, that that's poor tuning

i have B&B TriFlows, and they have a stock-ish sound to them without any drone. only slightly louder than factory LS1 mufflers with a deeper tone. the tips (rounded rectangles) look much better, too. granted i ain't done a cam yet, but i've got a TVS & ARH 1 7/8" LTs with dual 3" mids necked down to a 2.5" axle-back. i kept these mufflers for the interstate & coming home at night - the cutouts are for racing & mountain runs.
here's a google pic (no good ones of my own)

Thanks for your input Zebra. However I can tell you that a cam radically changes the sound of the car. I heard GHLs (the same as mine) on an almost stock car, and it's totally different on mine.
They only exhaust I will be able to try around here without buying will be the magnflow. I will do it and see what happens. I'll let you know how it goes, if it can help anyone looking to tame that cam sound

A new catback won't change the lope of your cam, only raising the idle speed, and fine tuning will that. That's a big cam, but should only have a bit of a lope on a 408. Other catbacks just change the sound tone, and overall volume level.
