sorry if i posted else where im new too this.....i have my turbo setup almost done and was wondering if i should leave the trd axleback on the car and have 2.5 custom done by a shop before the trd axleback...will this work good or any other ideas....is this a free flow exhaust...thanks

 

its not really good or bad. if you can get a custom exhaust, go that route. I guess for the time being your fine. but I believe the trd is 2.25 and you'll benefit much more from a 2.5.

 

Well, I suppose it's better then stock.
I have the Injen, which I belive is about 2.35 for the pipeing. I'm going to have a shop custom a 2.5 mid pipe to it, or I may have them do it all the way to the can on the Injen. But if your having a shop cutom one, it probably would not be to much more to have them throw a magnaflow or something on it. Then you can sell yoru TRD.

 

2.5 all the way

 

could i just do 2.5 with no muffler ? and i think the trd they said is 2.34 something like that.

 

3" is the best but the trd ids better than stock

 

its not gonna hurt your car but its costing you horsepower. the trd exhaust is not much different then the stock exhaust, just a little more noise. 2.5 or 3 inch full exhaust and you will make alot more power.. just changing the midpipe and exhaust on mine made a world of difference, i did the s pipe last.

 

ok thanx for the info im having the shop do 2.5 with the dynomax bullet muffler hope that works out well

 

yeah, the trd muffler just sounds good, no actual performance gains are made from it.

 

You can always get a s-pipe and a mid-pipe. I know a few people that did that with their TRD exhaust before or after they install their turbo kit.

 

the trd exhaust is the most restrictive. im speaking from experience. i got the most gain from changing the muffler and midpipe. i changed the s pipe last because i was told it was the most restrictive and i would have to retune when i did. i boosted a little higher, but not as much gains as i had with the other 2 pipes.
