i'm prototyping this exhaust through vinci high performance for bassani. bolts to the stock cats into an X-pipe. then continues dual over the axle into one muffler. then two out. once testing and fitment issues are resolved, pricing will be set. this is a tru-dual system.

here's the pics

 

Looks VERY nice. Looks VERY expensive. Bassani is first class all the way. Bet it's pretty quiet with stock manifold and cats. Probably more of a sound mod than a performance mod. I would imagine the sound would rival the best of anything out there.

From a power standpoint, I bet it would be really nice with their mid-length headers and cats. Keep us posted with sound clips and more pictures (especially how it merges with the factory cats, etc..

 

Looks a little tight around the PHB, nothing a little adjustable PH wont take care of !
Bassani from my experience is anything but quiet, even with ALL cats on a 03GT that ***** nice and loud, quiet at idle, but anything off idle and its sweeeet.
Anyway you can get a side ****, from a 3/4 looking up, so we can see the clearance and fitment from the side?

 

What size pipes are those?

 

Looks pretty sweet, looks great. Yeah I bet it will be expensive, but Bassani's quality is top notch from what I've seen. How's it feel to be part of R&D for our cars?

 

pipes are 2.5" it actually is hitting the panhard brace. not the rod itself. i have a hotchkis panhard rod on there right now. either i can cut one inch off the intermediate pipe that connects from the X-pipe to the over axle pipe or, i can notch the brace.

are you asking for pics under the door area to see the ground clearance? if so, it tucks up real nice. i have no ground clearance issues with it. even going over speed bumps. i have a sound clip i submitted to ls1sounds. didn't have it when i uploaded the pics using vinci's site. right now my computer is packed away until i move into the new house.

the low and mid range is real good compared to the cutout i had on the stock system. the X-pipe is really helping that out. and feels just as strong in the upper rpms as the cutout did.

as soon as i fix the tranny from toasting 2nd gear last night from too many 200 hp n2o hits, it'll be on the dyno and track. tranny builder can'tget to it until after thansgiving.

 

feels nice when you get to be the first person to test a product and be able to help in finalizing the product for mass marketing. the wife's car has the bassani optimum length mid-length headers with catted Y-pipe. i was the first for that one also.

downside is when people say you are getting all butt-smoochy, as one guy put it, when you post for the company you are testing for. you'll notice i post alot for www.vincihighperformance.com as well. i'm also doing the field testing on their handheld programmer. but they are just jealous is all. and no, i don't get all this stuff for free either. but, i do get for a good price.

the wife's and my car are on their site here under joe vinci's 409 cid LS1 and Crane Cams street shark car:
http://www.vincihighperformance.com/fbodyls1.html

next up from them will be long tubes with catted y-pipe. also catted pipes to fit this dual set up. i'm all for the next test.

 

as far as sound goes, inside the car is reall mellow and very deep. little louder than stock. as you go up in the rpms, it gets slightly louder, but still real deep. with no drone what so ever. kinda like a magnaflow. now, behind the car is a different story. i'm waiting for ls1sounds to upload the sound clip. i'm not using my computer right now. or, i'd have it up on my website.

 

I rode shotgun in the first couple of evaulation passes The db level was very docile in the cabin with the windows up at WOT.

I'm personally not a fan of those style of tips (nor of the MagnaFlow tips either), but barring exhorbitant cost I might be interested if they would fit in my application. Alas I don't think they would even with a custom y-pipe due to my torque arm.

 

looks good but i bet its going to cost some cash

 

Very nice! Any price estimates?

 

no pricing as of yet. still testing.

 

Whats the idea behind using one muffler with true duals?

 

simplicity. room constraints. ground clearance. they wanted this exhaust to be quiet as well as perform. bassani thinks it's to loud still. i personally do not. it's nice and quiet in the car. but behind it, it's medium loud.

 

imo, this is the first dual exhaust that caught my interest. I don't want loud, and even though my "old-school self" still likes the dual mufflers hanging below the rear seats, I think this exhaust's fit and finish would be perfect for me - assuming of course they work out all the kinks.

 

still no sound clip up at ls1sounds.com i want to hear this beast

 

well i can send you the sound clip if anyone wants it.

 

i'd like to hear it

i usually send clips over this network and it works well

Can you post it in this thread?

 

ok just sent the clip to master chief. problem with me is i'm using my father-in-law's iMAC computer. i had the sound clip emailed to me from my friend's camera. so i have it in my AOL email. i can't figure out how to download it and save it to the iMAC to try and attach it here. if master chief or anyone else wants to upload it, that's fine by me.
