hey guys i recently bought a black chrome HMF exhaust for my 700R... i put in on and it runs great... everything is stock except for the pipe!... it doesent backfire or pops when i decelerate and runs just like when it had the stock exhaust on just alot louder... after couple hours of driving my tps went bad ... it wouldnt idle anymore and would sputter at low rpm's but runs great at WOT!... i was just wondering if maybe the pipe had anything to do with the TPS going bad???... and even if it runs good with no backfiring or popping and my plug isnt white either ... if i would need a fuel controller also ???...thx for your help !
