Iv got a 2 dynomax bullet setup. Car is very loud and I'm thinking of changing up the mufflers to moroso spiral flows.

Ive seen that one and i think its just the quality of the camera and how it was taken. There is a red gto video on youtube with the spintech xpipe and catback and it sounds better than anything Ive heard.

I own theagnaflow 14419's. My setup is a three inch h pipe dumped at the rear axle. It is loud as hell. I do set off car alarms idling by in the parking lot (nine times out of ten a honda). How bassy is it? I feel like I'm listening to a test tone while cruising at 1500 to 2200 rpm's. It will make your ears ring. WOT is loud as hell. I constantly get 'I couldn't hear my engine over your car' from a lot of people.

Haha that's funny, how's my exhaust treating you?! I love the true duals it sounds AMAZING!!! lol I'll never go back to a y-pipe setup. It's now routed all the way out the back of the car.

I sold the car a couple of months ago, I hated to go to a catback, but ground clearance was a big issue for me and it was the only way to go. I loved the sound it made, just felt low on power after, but then again it doesn't flow nearly as much as true duals so it explains it, but the new owner seems to love it! Hopefully I'll see you at kemah one of these saturdays so I can finally hear what I wanted to do originally with that exhaust sounds like.

I have tsp rumbler bullets. I thought they would sound and be as loud as dynomax bullets. Surprisingly they are very quiet.

Im looking at swapping out my mufflers for dynomax bullets or 1 chamber flows. Im actually surprised how the xr1 sound.

Currently running bbk lt's, ory, magnaflow catback. The cb is too quiet and the cutout is too loud and raspy. How do the pypes m80's sound? suggest a pair of mufflers?
Guess I should have clarified. They are not installed yet. I have my mufflers,mandrels bends etc. True duals will be custom made next week.

So look for a sound clip soon.

Does suck, you can't find much TD magnaflow bullets floating around. I will make sure I get many desired clips. Idle,Rev,Drive by, WOT drive by.

I sold my tsp headers & true dual w/ sweet thunder to a member here. it was easily the best sound I have heard on an ls. I miss it.

Why'd you sell it then?

I needed to sell my headers and h pipe. A buyer was interested in the whole thing so I sold it. I was starting my twin turbo build and wasn't planning on running any mufflers

Finally got my exhaust changed over, I put the clip in my dyno thread and in the multimedia forum, but in case anyone missed it. 1 7/8" kooks LTs to offroad x-pipe into 3" borla xr1s
