I love the system, but I may have to go with something else because, I can't see myself cutting and welding the inlet pipes to rear of catalytic converters. Please tell me you are working on bolt ons or they are an option in the very very near future.
Hi! Our Axle-Back is a bolt-on part. The optional mid pipe does require cutting and welding behind the catalytic converters. We designed it this way in order to keep our exhaust system street legal.
@@borla I understand all of this, but wouldn't it still be street legal as a bolt on to the catalytic converters? I have your cat-back on my GMC Denali fully bolt on and its street legal. What if I decided to return back to stock, I can't. Love your exhaust but before I cut and weld on the Lexus IS500 I will go with an exhaust system that doesn't require cutting welding.
Unfortunately, there is no flange or break point before the secondary catalytic converters on the RC F/IS 500. The secondary catalytic converters are built into the stock mid pipes. This design is the only way to retain the secondary catalytic converters.
Many of the exhaust systems in the market are race systems and are not street legal. Any exhaust system that bolts up to the flange towards the front of the car removes the secondary catalytic converters.
I could be mistaken, but the only difference I know of is the IS 500 midpipe is a couple inches longer than the RC F. RC F axlebacks fit on IS 500, but RC F catbacks do not. Besides that, pretty much the same.
This updated system retains the secondary catalytic converters. Our optional mid-pipe will require cutting and welding behind the secondary catalytic converters.
