does it exist? a completely staight through 3" exhaust

I am in search of a straight through 3" exhaust. I am aware of only one and thats the magnaflow center exit comp exhaust which im not fond of. Does anyone know of another kit? I have looked at just about all of them. Im tryin to avoid piecing one together but if i have too id like some suggestions an pics of which ones would be the easiest too just replace the mufflers with straight sections. I will be running the TSP 2" lts w off road connections. I am very aware of how loud it will be i also am planning on running 5"tips or dual 4" tips

I would take a look at the Stainless Work Retro Chambered System. That's 3" all the way through. You do know your TSP connection pipes are going to neck down to 2-1/2", right?

JBA 3". It does have mufflers, but I think they are mostly for tone. I certainly have no desire left on the table for more volume!

"mufflers" is a good way to put it! I would have bought that system if I had done a little more research before I bought the JBA. They sound similar, and SW is made right where I like it.

MBRP and Stainless Works retro chambered catbacks are 3" systems like Chase pictured above. They will neck down to 2.5" to meet the factory connection point unless you order the performance connection from Stainless Works. Not sure if your TSP headers will bolt right up but I would imagine you can make something work pretty easily.

just gonna throw this out there, there isnt a huge benefit to a 3" on a minor bolt on car, just straight pipe your 2.5, buy headers over a 3"

I have the LS3 3" T304 MBRP X-pipe catback on Kook's stepped catless headers. It's damn loud IMO. Just ordered the L99 resonated x-pipe direct from MBRP to tone it down a bit. Def straight through and a bit of drone even on the LS3 in 6th under 2k rpm.

Okay, well, not to sound "ignorant", but your catless connection pipes that connect to that 3" collector neck down to 2-1/2" in order to connect to the factory-style exhaust. So...unless you are buying some custom-made straight 3" connection pipes from somewhere other than Texas-Speed, then you WILL be necking down to 2-1/2".

I think Stainless Works may sell those straight 3" connection pipes. They call it their "Performance Connect" system

yea but lets be honest. He isnt bottlenecking any additional power. The general misconception is he needs a 3" to open power and its just incorrect.

Yep, I agree, there's no big loss of power from necking down to 2-1/2". But I just wanted him to understand that his Texas-Speeed headers with the 3" collector WILL narrow down to 2-1/2" at the outlet of the connection pipe.

Having a muffler doesn't mean it isn't a straight through design so I'm not sure you're clear on what you're looking for.

that is accurate, I just dont understand guys buying a 3" catback when all they have is headers and CAI... the 2.5" is fine for what they are running

Camper im on a mission sir an N/A mission and ive set the mark very very high flow=hp. It will be impressive for sure especially for an a6. My approach is taking the best of the best and doing it better. The exhaust is just what i wanted and was hoping too find a manufacturer that was ready making it. Btw who does have the highest know hp N/A L99?

You can get a 3 inch catless connection from tsp also. I did to connect to a 3 inch cat back. Just have to ask for it instead of the 3x2.5

I have the Maganflow 3" comp center exit. I think I'm the only one who has it. It sounds cool, but it's hella loud. I'm actually looking to switch pretty soon.
