Hello everyone I have a 2006 C6 base model Corvette that I recently acquired. It came with an axle-back Borla exhaust but I cant figure out which one it is? Anyone know?
Also what is the cheapest way to make it louder without losing the deep roar that the Borla currently has?

Thank you everyone!!

I've not looked at a Borla system installed on a Corvette up close, but I had a Borla catback system on my Mach-1 Mustang and it had the part number stamped into it. Maybe yours does too? If no one here identifies it, I expect sending those photos to Borla would work.

Look on Borla's website to find the pipe layout that matches yours???

Can't help with the type of borla exhaust.

Cheapest way to make it louder is remove the resonators. You're in california, so that car should have 4 on them. However, people got recalled on corvettes in CA to add 2 more resonators on them (initially only have 2) so you will fail smog if your car comes up w/o having that recall done.

Not So Fast

Resonators ????? I don't think so but could be wrong, are you talking about the cats ??

They look like the Borla Stingers. They look like the same ones I have on my '07. I used to have the full catback system. Mine got a bit louder after I installed the Z06 exhaust manifolds, cats and H pipe but kept the Borla mufflers.

Adding a set of long tube headers surely would make it louder

Oh you're right. My bad. It's the cats. 2 to 4 cats!

Soo removing the cats will make it louder but will also fail smog unless you take it to someone and do it under the table.

While this method is a pain in the *** when smog comes around, it's probably the cheapest option still than buying headers + install + tune

It looks like the Borla Type S axle back.

Like others have said put headers on it or trade the Type S for Borla ATAK to make it deeper and louder.

The tips and mounting hook look different than my Stingers.

As noted, its the older stinger tour type mufflers.

If you want loud, then you want the new Borla Atak mufflers.

Those are the old style Borla Stingers that i have on my 08 with headers and they are very loud...Ask my neighbors..

Headers with high flow cats make any muffler system about 4 times as loud. Hence it not only the headers, but the delete of the OEM cats to high flow cats after the header collects part of the differeance. Hence the oem cat acts like another muffler in line, while high flow cats, not so much instead.


OP, the reason you want high flow cats with Headers, is so the car is not stinking of un-burnt fuel every stop light. As for the high flow cats, only robs you about 4hp, and well worth the few HP loss so the car is not stinking of unburnt fuel isntead. Hence gets bad when you are sitting at a stop light and the inside cabin reeks of un-burnt fuel as well.

Can you do a sound video of that exhaust...Thanks

Looks exactly like the Borla S Type classic that I had on mine. I couldn't stand the drone and got rid of it after one month.

I bought an out of state car. I live in CA. Haven't done the smog yet, so you're saying I'll fail smog?

I believe that only applies to certain 2008 and 2009 LS3 Vettes that came with 4 cats.

i thought it was all the C6's but obviously that recall states otherwise so just ignore what i said

Correct: for 2005-2008 only, and they were "Stringers" part #140128 I had them put on my 08 and love them. Borla now has two other S Types that will fit on vettes from 2005-2013,but they changed the inlet and outlet pipe size and the tips are different.

doomi: They had the round tips and the oval tips.Tne Stingers on my 08 were on my 07,in the later years Borla changed the pipe size.The OD pipe size to my oval tips are 2.5" and a few years ago Borla went to 2" OD to the tips...Why??
