hey guys im gonna go underdrive pulley and an injen cold air intake and i was wondering if i need to upgrade the exhaust system, i mean will i be able to safely run these mods without running codes b/c i didnt upgrade the exhaust?.TIA

 

You'll be fine without upgrading your exhaust. Not that you won't want to for added performance in the future, buy you won't hurt anything if you don't do it right now.

 

You won't throw codes, but the exhaust will compliment the combo nicely.

 

^^^ yes it will you will get a nice throaty sound with the intake but it still sounds nice stock

 

upgrading the exhaust will make you more likely to trow codes especially if you put in the header/dp or get rid of your cat.

 

Do it as is. You really don't need to upgrade the exhaust untill you turbo. It's mostly for sound and really your giving up a little low end to get a little high end with exhaust. Even at that it's like 1-3 hp

 

stock is good but aftermarket is better, not really helping .....sorry

 

there is nothing wrong with the stock muffler with those combo's, thats how i started out except i went with the SRI becasue i hate cleaning the filters that often etc, but when i threw the magnaflow CB on it was even nicer, the intake and exhaust just seemed to work nicer together, and you could hear it, with the stock i was tried to start it when it was running! yes i am a moron....but it is so quite, especially at idle.

 

Breathe my friend breathe.. that's what you want your N.A car to do.

 

if you really dont want to have a stock exhaust then go axelback or universal muffler, thats about the cheapest way to go unless you have the money for a catback or header back.

 

gottchya, i mean everyone asks if i got exhaust work b/c my exhaust stock is really pretty loud, i was debating whether to do anything to the engine, but i just got beat by a scion tc with intake and a full out custom fabricated exhaust, and im pissed, so now i want some mods thanks for all the advice guys, gonna go and buy the pulley and cold air intake now

 

even if you get the sri, udp, and axel back exhaust you still may get beat. A lot of people don't realize how crutial knowing how to drive is. Someone that knows how to drive can easily beat you off the line and pull away. Thats what I love about our cars. We have a lot of torque and once you learn how to feather the clutch just enough when the "tree" turns green you go WOT and leave them in the dust. Just be careful and remember always keep your racing to the track

 

If you can, get the motor mounts and shifter bushings too. That will help a lot with wheel hop and shifting. These are good places to start without breaking the bank.

 

yea I got waxed by a lude....but I would say just wait until you get a turbo for a new exhaust....thats what Im planning on doing

 

The exhaust after the cat is not the restriction. its the down pipe area thats all kinked and nasty. if you really want to upgrade the exhaust portion just get a down pipe, if RRM still has em, or the Header D/P combo. That is where you will notice the gains, but eh that is my own two cents. eventually, yeah sure get a cat back but even with all my mods I am just considering to upgrade the portion after the down pipe. Mod according to your goal. Dont just buy buy buy parts just because every other car has a modified exhaust and think you are going to get neck snapping power. Save time, energy and money.
