Don’t know if this is the right group for this but my exhaust is sounding extremely off when the engine is cold I can take a video off the noise don’t know what it could be. Also the car vibrates a little when idling or stopped just had a timing chain kit out in last week.
Alright this is like going to be hard to describe but basically the exhaust sounds like it’s alternating between the exits in low rpms especially when the engine is cold. Can hear it pretty well around 2000 rpms just wondering what could be the cause I’ve got a xpipe in the mid and straight...
I’ve been dragging my feet for the last year on whether to upgrade my exhaust, and I think the time is coming to do so!
My main concern now is making sure I don’t do something way too loud (I do want it to scream at WOT though). I have an x-pipe with solo axlebacks currently, and I’ve seen some...
Hey there! Back with another question. The shop says I should replace the center pipe/resonator, so Im looking around for an x pipe to replace it with and some new mufflers. I keep seeing everyone else giving different sizes for the diameter. Is it 2.5 or 2.25?
I bought these and then discovered I cannot use them with my current exhaust. Yes, I am getting Kooks long tube headers in the near future but will be connecting them to a non-Solo catback exhaust system. I thought I could modify these to work but then realized a solution where I will reuse the...
My exhaust mods consist of Solo axle-backs and an x-pipe, and additional mods include a CAI and a Cortex tune.
I've been doing a lot of reading, and I'm hoping to determine the best exhaust mod from here. My goals are HP and sound. My current sent up sounds really mean at startup, but not so...

So it seems like most are in agreement that a cat back on an otherwise stock G8 should add approximately 10 hp give or take. I want to know how much hp gains can be had from any full cat back on my engine over the stock exhaust system.
I’m doing a dod delete on my 09 g8 gt. Cam specs are...
So i've been browsing around on G8Only and I was wondering if anyone here has ran the "Wake the Neighbors Package" just want to see if it's worth it or how it sounds.

I apologize for reposting, but I wanted to be more specific with my questions.
I purchased a Gibson Axleback, and I'm looking to modify my otherwise stock exhaust to get more rumble, and less drone.
The options I'm evaluating include:
1. Magnaflow 12468 in place of the mid-muffler. This will...

I have a 2009 G8 GT with the stock exhaust and am currently shopping around for a new cat-back system. I'm looking to get something that isn't annoyingly loud but will complement the 6.0L under the hood. I have looked into Flowmaster, Corsa, and Magnaflow. What system would you recommend for the...

The Catback is still fully assembled and the center connections have tack welds to keep them from sagging over time and hitting the cross section.
This bolts up to stock locations. I am not willing to ship. 48316
