Greg_E 211 Posted May 5, 2013 Share Posted May 5, 2013 Difficult to tell just how much difference it made to the noise level. Assuming a straight pipe, have you considered one of the Magnaflow mufflers adapted to fit up under the bodywork? Link to post Share on other sites
70-yenko-nova 12 Posted May 5, 2013 Author Share Posted May 5, 2013 the cars are already to quit in my case If i keep it im going to bypass the 2 mufflers. straight pipe bike and out with minimal bends as possible. and ill try n get a compare. Link to post Share on other sites
70-yenko-nova 12 Posted May 5, 2013 Author Share Posted May 5, 2013 (edited) it's pretty noticeable.... its only unbolted (2 15mm bolts) from behind the second cat which is under the shifter.... unbolt it pull them apart... give it a shot.

Greg_E 211 Posted May 5, 2013 Share Posted May 5, 2013 If you run it long enough without a muffler you might get an error code for the cat. not working properly. Because we have yearly inspections, I would go with something that looks like a muffler in the back, even if it was nothing more than perforated pipe with a box around it like some of the Magnaflow mufflers. That way technically I have a muffler installed even if it is a straight through design. Link to post Share on other sites
70-yenko-nova 12 Posted May 6, 2013 Author Share Posted May 6, 2013 (edited) its after the cats and the o2 sensor so it shouldn't affect anything honestly..... Also pics of headrest delete (so much more room to see omg... Eliminates all blind spots) and black front emblem Edited May 6, 2013 by 70-yenko-nova Link to post Share on other sites
austex04 48 Posted May 6, 2013 Share Posted May 6, 2013 I would be concerned that could give GM a reason to void emission warranty. Sounds kinda mean, but also like my old Geo when the muffler fell off after a few midwest winters when I moved out of state . One of the reasons why I bought mine was because the engine is much quieter than the Accent, and much less harsh when revved. You should check out some of the performance mufflers that people use on Hondas. Those mufflers should give you the right sound you want, and would not void any warranty.

Hobo1 8 Posted May 6, 2013 Share Posted May 6, 2013 Honestly I am scared to touch my exhaust because of the warranty :/ Link to post Share on other sites
70-yenko-nova 12 Posted May 6, 2013 Author Share Posted May 6, 2013 What would the void the warranty OF? the cats are just fine? The o2 sensor will read perfectly fine (its another 4 feet up the exhuast with a cat in between the opening and the sensor. What warranty could/would they void? Link to post Share on other sites
70-yenko-nova 12 Posted May 6, 2013 Author Share Posted May 6, 2013 (edited) If anything DID go wrong they would have to prove without a doubt that whatever went wrong WAS caused by having no mufflers. It's not like a bent valve would occur we ran open headers for 3 and half seasons and nothing happened to our car. The cold air going back in an exhaust is bullshit The idea is that valves warp and then lose enough contact with the head for heat dissipation. I've also seen people saying that exhaust leaks can do this also. The theory is that upon shutdown, cold air can reach the valves and warp them especially if they are open (unseated from the head). Which if open headers really burned up valves then lets bring into context WW2 fighters.. they were designed for longevitiy AND power... and they never burnt valves up every flight like people like to make it seem. if you run open block yes.... Somewhere I read it only takes 3 inches of piping off of the exhaust to be enough to prevent burning of valves. So valves and engine are completely out of the question. LAstly..., The Magnuson-Moss Act Modyfing cars while keeping warranty coverage has a great deal of gray area. Although many dealers would have you think otherwise, simply having an aftermarket part or modifying your vehicle cannot void your warranty. Some dealerships may say 'just because you have a "INSERT MOD HERE" or something that the whole vehicle warranty is voided. NOT TRUE!! Magnuson-Moss Warranty Act of 1975. The act states that a dealer must prove that aftermarket equipment caused the need for repairs before it can deny warranty coverage. The burden of proof is on the service department and manufacturer to prove the issue in question is the direct result of the "MOD". If they can not do that then they have to honor the warranty. CLIFF NOTES... MOD YOUR SHIT DO IT PROPERLY DON'T CAUSE DAMAGE.... Edited May 6, 2013 by 70-yenko-nova Link to post Share on other sites

tommyspark 24 Posted August 20, 2013 Share Posted August 20, 2013 (edited) Modding a car with a warranty will not void the warranty so to speak. If you put a different exhaust, or mod the stock one, obviously this will void the exhaust warranty. If you lower a car, you void the suspension warranty. But as far as the actual engine being covered, you'll be fine. My G6 broke down March 2012. And I mean it broke down to the point that GM sent a wrecker to come pick it up to take it to the stealership. The tow was even free; covered by warranty. At the time they took the G6, it had an aftermarket CAI, aftermarket ECM, and was straight pipe. Well it had no cat and a catback Magnaflow exhaust. They fixed the car; under warranty. No big deal Edited August 20, 2013 by tommyspark Link to post Share on other sites
