Is the headerbolt pattern the same as a 22r ? They have headers at summit racing but don't know if they're same ? One was $136.00 not bad .I had bought the SS quiet cat back exhaust for my tundra from them it had 3 inch pipe stainless and it was 130 bucks it sounded louder than stock and quieter than the flow master .they have it for taco as too .but its 2.25 pipe. I wonder if I can make the 3 inch tundra exhaust work on a new Tacoma .the shape looks similar and it will bump to 3 inch cat back .hmmm?
