Just ordered my Spugen Single Titanium V.2 Exhaust. I'm debating on getting a J's Racing Header down the road. I'm now wondering if having such a large header and a relatively average sized exhaust would limit my gains. Of course I'd get more with a J's 70mm or Amuse R1000 but I'd like to stay as close to street legal as possible. I'll be using it to it's potential on the track, otherwise it's a weekend car just for driving around, so high rpm gain is what I have in mind. Any opinons?? Thanks!

 

Get a bigger exhaust for your bigger header! T14 70r from AJ-Racing!
