i just put on my new borla took an hour i thought everything went well on fitting and stuff i was amazed on how quite it was until you got on it....imo, my qeustion was i dont feel no horsepower gains shouldn't you be able to tell a little bit if its supossed to give 7-10 hp at the wheels is what i was told?and it had a real funny smell when i stopped after running it anyone else have this kind of experience?

The funny smell is the mufflers being broken in, nothing to worry about. As far as the HP increase, you really won't feel anything from the exhaust since the increase is so small. Enjoy the exhaust and wait for the intake shoot out and make your choice. I made mine already and with the exhaust, the car sounds nice. Enjoy

i have a akimoto intake that makes my car lag on take off but i heard its because of the ecu not registering the beter air intake. and when i smash on the gas i hear like pinging or knocking from the valves any thoughts?

biggie27

knocking is never good I would suggest getting rid of that intake, or buy an S-AFC and tune your fuel/Air ration as soon as possible

Neither did I feel the difference when I put on the Borla on 430.

I have the RMM ie couldn't feel big diff. Remember it is not tourque it is HP. Big difference. As far as the sound it will get better as it breaks in. 2000k. Intake swift with stage 2 ecu also (I felt the diff. then!) T/C from RMM felt big diff.

My car feels faster than ever now - maybe it's just break-in, but maybe it was the mods. I thought it was a bit better after the drop-in K&N filter, and then I thought it was a bit better again after the L-Tuned exhaust. I don't have an intake, so no lag there. A friend has a 430 and just came in my car and said it seemed MUCH more responsive than his.

I got the K&N drop in filter I noticed a big improvement once I reset the ECU, even some of the guys that work at the Lexus dealership here say that my car is very quick, even compared to a 430. I am soon gonna get the l-tuned exhaust or the borla, Once I do that I'll get my car Dynoed if it lookes good I will probably not get any cold intake system, As it is dusty here where I live most of the year. Also I dont really want to change that much of my car, It is a Lexus not a honda!.

navaz, I got 238HP and 252TQ on the dyno, which is decent without an SRT intake!
