Title: Hi flow cat

Post by: Janner_Sy on December 14, 2010, 12:10:58 am: yes i hav ran this and the full system. doing it this way means you get ALL of the performance gains, with a nice little increase in the burble. if you were to add the cat back ontop, you get more noise and that is it, negligible performance gains in my experience

If you need a downpipe we now have 5 in stock (ordering mistake) and may sell them off at a good price if we can get orders for all 5 off here.

as said in my first reply, yes i have ran it like that and with the full system. I for one would never buy the cat back again as it made a stealthy car too loud and it was blatantly obvious when i was speeding

Post by: craig_t on December 28, 2010, 08:25:41 pm: whats the noise increase???
Title: Re: Hi flow cat
Post by: Janner_Sy on December 28, 2010, 09:28:54 pm: Theres not a large noise increase in all honesty. yhowever the exhaust note did change alot. It became alot throatier and deeper than the stock noise.

My next car will only be getting a downpipe this time, and not the TBE as it did everything i wanted. gave the perfromane gains and made the car sound better without shouting chav. The full TBE sounded ace on track, but it was to much for day to day driving for me.
