has anyone installed these on a stock GTO and what do they sound like? is there a lot more interior drone? are they a straight cut and weld in place of the stock muffler? lastly, how much do they weight each? i'm looking more for weight reduction than making the car louder. i just dont want to do the muffler delete. it's just to damn loud in my opinion. thanks guys.

I'm sure they will sound a lot like the SLP Loudmouth II's. Try a search for a video or audio clip of the Loudmouth II exhaust. Either way, they will sound good. Loud but just tame enough!

Havent heard the Dynomax Bullets, but I tried the straight muffler delete and I didnt mind the loudness, but the raspy sound when you back off the throttle was terrible (IMO). I changed to magnaflow 4" round mufflers. They are straight thru but have no raspy sound. I get a lot of compliments on it sounding like a GTO should sound (of course opinions vary). I think it is a good alternative and is a significant weight difference (20 lbs per muffler vs about 6 I think). If you need the part # let me know and I will dig it up.

i'm putting the dynomax bullets on tomorrow. they're going to be ahead of my spintech pro streets. the spintechs sounded absolutely awesome with a very rich and unique sound but they were too loud with my !cats, !resonator, LT system so i'm putting the bullets on to tame it down a bit. i'll let you know tomorrow how it comes out.

the 4" DynoMax bullets with 3" inlet/outlet weigh 6# each. i had them put on this morning. WOW!. they are inserted in the 3" midpipes right behind the collectors. combined with my LTs, !cats, !resonators, 2 1/2" pipes and Spintech Pro Streets it is awesome. the bullets lowered, quieted and smoothed the note a bit but it still has that Spintech snarl at WOT. i'm very happy. great SOP mod too. i'm taking her to the track tomorrow and see what she does.
