Well, I ended up going with a true straight pipe exhaust. The stock cats were removed and replaced with a custom O/R midpipe, because racecar, and the stock x pipe was left intact. The car already has SLP Loudmouth straight pipe ABs on it...
All I can say is... damn. I will try and grab another video that does them justice.... they are nascar loud. A lot louder than I expected. I couldn't find many posts or videos with GT500s with o/r straight pipes...but the few I found sounded amazing.
Unfortunately I lost a ton of back pressure...I have to rev extremely high to get moving, and it's just obnoxious....
When I turn on the car it roars to life...it's amazing... the idle almost sounds slightly cammed out and resembles that of the old school muscle cars. I got a lot of thumbs ups from people while idling at red lights...and even had an old cammed out challenger give me an approving head knod and wave.
Once the light turns green it's terrible. No back pressure and loud exhaust is a recipe for failure. There is also no real tone to it. Just kind of chugging away, for lack of a better description. The exhaust barks at 2k rpms so I shift st 1900 every time so I dont make people deaf. I let it get up to 3.5k rpms and it was just ridiculous... I feel like it's too loud and will attract unwanted attention...I also can't drive the car too late at night now out of consideration for my neighbors.
I really don't want to put the cats back on... so I'm trying to figure how I can keep the amazing burbly idle, regain back pressure and torque, and have a slightly less nascar tone while cruising... if I go WOT I'd love a nascar tone...but for daily driving speeds it isn't suitable.
I never thought I would ever say my exhaust is too loud...but it really is. I'm trying to figure out the most cost effective solution to my problem. I'd love to find someone's old KR mufflers for a couple hundred and throw them on. I think that would help out immensely.... I'm open to other suggestions though.
