Top Speed Test Pipes a few years later
 

One of my secondary cats caused a CEL and time to replace one of them. I like what I have read about deleting the secondary cats which I am learning serves no purpose.

I am considering buying the Top Speed test pipes and have PMed a few members but no response yet either due to the long weekend or other factors. Anyway, I am curious to know who has been running them on a 2.7 base boxster with stock muffler and how has their experience been with the product? Some have said that they were happy shortly after they installed the test pipes but I would like to see comments from those who have had them on their boxster for a year or longer.

Thanks in advance

Yep I will follow this ;)
My apprehension is about the fitting...

I don't know how much help I am, I have a 3.2, and I put the pipes on in January, and I have the TS exhaust, not stock. I am very happy with the performance gain and the sound. No complaints. BTY, I am 52 and didn't want an obnoxious sounding exhaust, and the TS exhaust with the cat delete pipe is not obnoxious, at least for me. At lower RPM's, it sounds more like stock, but as the rev's climb, you are going to love it:D Go through a tunnel or under an overpass and just try not to grin:cheers:

My test pipes have been on a couple months and love the sound (along with my NHP exhaust). I put them on myself and took a little finesse but fit perfect. Passed my local DEQ in Oregon today with no problems.

I've only driven with them on for 3 months but have no regrets. They deepen the sound exactly the way I hoped ( stock muffler). The fitment was OK. Try 'em!

Mine are on the way to pair up with TS exhaust, will give my impression next week when I install them.

Do y'all have a link to where you purchased the Top Speed test pipes? I'm looking at the Fabspeed, but hoping to spend a few less $$ in the process...

Thanks!

I could never get my set to stop leaking when hot. I eventually paid $50 to get them welded into the system and it was totally squared away.

At one point in my setup, I ran my 2.7 with stock headers, aftermarket test pipes, and stock muffler. No problems, was quite happy. For me, the fitment required a bit of working with to get complete. A little more sound and power, and weight reduction- was pleased. Currently have stock headers, aftermarket test pipes, and muffler.

no problems with this set up and going on 2 years now. half as loud as my 996

Thanks guys will keep this in mind while I make my decision on them
