    I have a 2.5” xforce catback and 4-1 1 7/8 extractors. The catback has mufflers in the mid and mufflers at the rest. So you could imagine it’s quiet. I plan on going to a 3” when I cam eventually but for now I want something a little louder or something that will change the note, so.
    If I go straight pipes at the rear the sound will stay the same but be much louder as opposed to hotdogs on the rear which wouldn’t be as loud but change the note slightly. Is this correct or am I missing something? Recommendations also are appreciated

    Has the motor had anything done to it? If not those extractors might be too big. A 2 1/2 catback would be the right size. My ve had a 3" catback without a centre muffler when I bought it. I took it off because it droned too much. A 3" catback is too big for a standard motor and likely produce less power than the 2 1/2 system.

    I’m going for a 3” when I plan to cam. And got the headers to suit what will flow the best, from my research that’s the best flowing stuff you can have for a cam?

    All I’ve had don’t so far is full exhaust, air intake and tune so next up is a cam. But I’m just wondering what will make my current 2.5” a little louder. Keep in mind I’m only wanting to swap the rear mufflers around instead of wasting cash on a new 2.5” when I’ll be going 3” eventually

    Try these j pipes. Reduces drone without the muffler or hotdogs. 54D6B3E7-C33A-437D-9CE8-71F570101F0B.png

    Yes much louder, the “J” pipe reduces or cancels out the drone. I had a set of 3 inch “J”pipes on my 2 1/2 exhaust and was loud.

    I’m not overly worried about drone it’s been pretty good so far. I drive a 6 speed also. Have you had any experience with straight pipes or hotdogs on the rear?

    Yes I’ve got hotdog rear pipes on my SS. Minimal drone as 6speed manual, nice idle sound, quiet cruising and loud when accelerating.

    I’m thinking I will try them out, easy to change back over if need be. I had a bad experience with hotdogs on my v6 ve it was loud and so much drone it’s was the absolute worst. Was also auto
