I just got a base car with an MS3 cam, long tubes, no cats and a BBE PRT axle back. Its way too loud.
I'm looking to replace the axle back with something to tame it down and came across a Z06 setup which was probably swapped for something louder. Will I take a performance hit going to an OE Z06 axle back? And how does it compare to a base axle back? Is it the same piece but titanium?
It's much less restrictive. Do some searching on this site, there was a ton of research done by others that showed that the TI exhaust is not restrictive at all. I loved my Corsa exhaust, but ended up going back to TI because it's a little quieter with headers.
The Ti exhaust is very high quality, I don't think you would have any noticeable performance differences. You *may* also have some weight savings compared to the PRT.
I kept the stock Ti stuff on my Z06 and had bypasses welded in. This was right before I put on TSP Long Tube Headers. Don't have any flow data but it is straight piped at this point, little louder.

There is no "may" about it. I think the Ti system is about 2/3 the weight of the steel. The Ti one is Ti from front to rear.
I don't know at what point it becomes a restriction but a friend of mine had it on his N/A C5 with a 434 and it was a 20whp restriction. 550whp with it and 570whp with it disconnected at the axle. Replaced it with LG big 3 and it was 568ish.
For others here beware the TSP long tubes as they ride low. If you go over anything tall you may center high scrape the pipes and if you lower the car you're going to not have fun on transitions. The Speed Engineering are the best for the money. There are also TPS (note the difference in letters /company) who sell a tightly fit long tube kit but their customer service is lacking and not to be trusted I feel based on my experiences. Still, it tucks up nicely from what I have seen of others. Kooks and ARH are great fit too, but much pricier.
Looking at the pics, I bet the bypass mod is good for some HP too!
There are a lot of reasons to do what we do as car guys, and whether the Ti is worth 20hp or not- my justification for keeping it is it straight up sounds badass
Maybe here in a while I will dyno non-bypass and bypassed Ti and see if there is any delta

I did that because I saw it done with the stock C5 Steel Exhaust and figured why not do it with the Titanium one. Definitely sounds good.
If you get Dyno numbers on it I'd definitely be interested.

Z06 Axle back restrictive?
