ditch the cat...

I have a 2.5" test pipe and a 2.5" borla xr-1 muffler, it was perfect, in my opinion, until I went with #8 hotside. Now the car drones a lot in town at feuding speed, so I'm going to add a resonator.

A 951 will never sound like those rolld back,wind up, and go hotwheels(Honda) we used to play with as kids... They sound more like srt-4s with huge exhausts, crackling while slowing down and backfiring hard between fast shifts....

like a real race car?

Meh, I hear american v8's with all sorts of different exhaust configurations every day...

The sound of a nicely tuned turbo 4 banger is much more interesting

Oh man, listen to that spooling turbo! Nice Patrick!

Yeah I kinda like that myself!!

Your turbo spool does sound very cool I wonder what causes some to be more pronounced than others ? I have used 4 or 5 turbo's over the years and all have been mild on the spool sound.

For some reason GTs have that really cool "jet spooling up on the runway" sound more pronounced than other turbos.

It is probably the anit-surge / map-width-enhancement porting on the compressor housing... Holsets have a really loud spool too.

The previous owner of my car did this video; 4" Lindsey Racing exhaust with Magnaflow muffler and Flowmaster pre-muffler. There is very little or no difference with the cat installed instead of the pre-muffler.

I have some videos on youtube of my SFR 3" test pipe/cat-delete/cat back with a Borla XR-1. I'll throw them up later.
