side pipes on a sx4

[pigonawing]

Hi guys i have a set of side pipesthay i would love to put on my sx4 using a Y pipe to split it they look great on the car in the mock up phase but before i destroy how much power if any will i lose having a lack of back pressure the car is already a bit of a dog for the 258 motor and i dont wanna make it worse for a cosmetic upgrade. but it dose look great haha my thought is no cat no muffler just the baffeled side pipes and a Y pipe to split any suggestions.


thanks
mike

it should wake the engine up rather that restrict it

My stroker utilizes true 2" exaust duallys. It runs through glasspacks. I love it.

I however had to crimp the drivers side to accomidate the slave on my tranny.

It runs like a banshee. Squealing the drivers front when shifting into 2nd gear. Let's not talk about 3rd.

Lake pipes would look sweet!!! I love how those look, Id put em on my wagon if I had em! they give the car a very aggressive look.

Remember you have a Krayton cladding on the sides -- side pipes may melt them.

Good call! There would definatly have to be some kind of heat shielding in place.

most of the side pipe kits out there have a good heat shield with a good 2 inch space between the pipe and the shield  but I would take short trips once installed and see if the rocker covers are getting hot

Mike, that sounds like a great project.  When you get ready to do it I'd like to lend a hand if I can.  I just replaced the exhaust last summer on mine from the cat. back.

i know nebraska has no emmision laws you do not have to pass inspection or anything and the whole exhast is on its last leggi already have the side pipes just need to find a way to to mount them so they dont melt anything but if there is a bad cat can that draw away from power too

yup, the material in the converter can break loose and plug up the system.  what i would do is get under the car and bang on the converter and if there is heavy rattling that is most likely the source of your problem.

You also mentioned no kickdown, if the car is an automatic I would make sure your kick down rod is connected adn in good shape because if not you may need a tranny pretty soon
